Britain might be out of the EU but we still continue to mirror many of their policies - and that particularly applies to climate change, energy savings and sustainability. Fire risk following Grenfell, also remains a major factor and both continue to provide massive challenges for Facility Management companies – especially when it comes to roofing and waterproofing writes Justin Pitman, sales director for Proteus Waterproofing. In spite of these factors, it can be proven that Facility Management professionals prepared to work more closely with suppliers can more easily meet these challenges, get the best quality job and make significant budget savings at the same time. Every building needs a roof, but in today’s green environment it is not enough to simply provide the waterproofing. New levels of insulation are needed to meet updated regulations and in the case of flats there is the added requirement to insulate party walls and other sensitive areas while also taking fire risk into consideration. Insulation levels are 10 times higher than they were 50 years ago. However, while fire regulations have not changed dramatically in recent years, amendments have been made following the Grenfell tower fire, in particular the ban on the installation of combustible materials in external walls on buildings with a height of 18 metres or more, introduced in October 2019. The Climate Change Act 2008 set in legislation, the UK's approach to tackling and responding to climate change. It introduced the UK’s long-term legally binding 2050 target to reduce greenhouse gas emissions by at least 80% relative to 1990 levels. Since 2012 there has also been a need for all commercial buildings to have EPCs (Energy Performance Certificates). These include buildings used as places of worship and for religious activities. stand-alone buildings of less than 50 m2. industrial sites, workshops and non-residential agricultural buildings with low energy demand including temporary buildings, offices, pubs, shops – the list is endless. The lower the energy use, the more attractive the building to potential end users. With this kind of pressure, it means that the building sector is crucial in achieving Britain’s energy and environmental goals. The good news is that following the introduction of energy performance rules in national building codes and the increased levels of insulation, buildings today consume only half as much as typical structures from the 1980s, but the rules continue to become more stringent and that in turn squeezes budgets. This all adds up to increased pressure and with fire and energy savings setting the agenda, more and more Facility Management professionals are asking companies such as Proteus to help them remove unnecessary costs from all parts of the supply chain. On face value this means offering the most competitive prices on product, but it is a much bigger story than that when set against the much bigger challenge of energy savings and fire risk. In response Proteus has developed a system and product offering to enable them to offer Facility Management professionals a complete roof design package incorporating living roofs (green, blue or brown), solar roof options, safety fall arrest systems and wind uplift calculations alongside their established waterproofing, insulation and fire protection system solutions. This ‘one-stop shop’ approach has allowed the company to provide a more competitive quality to their clients, whilst supporting them through the entire design and installation process. This has resulted in the removal of unnecessary costs and other overheads. In spite of these challenges, upgrading roofing and the waterproofing of other public areas can be incredibly disruptive and unpleasant for residents or office workers who have to remain in the building. There is also the risk of fire when torch on or molten materials are used. The good news is that the development of cold applied, odour free waterproofing systems has significantly reduced this problem and when used in conjunction with plans to increase insulation levels and reduce fire risk, they offer an incredibly cost-effective solution for Facility Management companies. It all adds up to major changes in the way that Facility Management Companies should be dealing with end suppliers. Closer collaboration with everyone involved in the supply chain means that the end user gets the best possible job. It is also the most cost-effective solution for Facility Management professionals when they are prepared to work more closely with suppliers and installers by letting them take the strain in terms of design advice, risk assessment and all the other factors which now dominate the modern construction industry. It is no longer about fighting for the best product price so why let roofing and waterproofing be a challenge when all the expertise you need is on the doorstep.0 Posted by Talk. Build

Bitumen has always had a bit of a bad record when it comes to getting an excellent fire rating. It must be emphasised of course that there are many products that contain bitumen, probably our oldest and still one of the best waterproofing materials available, that are hard to ignite even with prolonged direct flame – but that is another story. The material is a key ingredient of roofing felt which is traditionally torched on using a naked flame or requires molten bitumen to achieve a waterproof seal. The dangers of working with an open flame on any building or residence should be taken very seriously. With all the precaution and experience in the world, the law of averages is against you when you spend the entire day with a naked flame at high volume onto a building. A simple Google search with the key words ‘roof torch fire’ will present you with enough articles on fires related to torch applied roofing to leave you wondering how anyone would ever use this product. There are and have been for many years’ cold applied self-adhesive felt membranes but they still represent a small part of the total market and are not universally popular with roofing contractors So in spite of its reputation torch on Bitumen Felts still dominate the flat roofing market but according to one leading manufacturer, Proteus Waterproofing, based in Rayleigh, Essex, it is possible to install such a product using naked flame without the risk of fire. They have a top waterproofing layer or cap sheet that can achieve the highest fire ratings - and Proteus have added it within a new range of felts recently launched on to the market. The age old problem is of course, that a fire rated cap sheet costs a little more than one without the same high level of protection and in spite of the lessons of Grenfell price is still king and many contractors seem reluctant to go that extra mile in the interests of increased health and safety. Key providers are still not pushing the top fire rated membranes as much as they could or should, due to this increased cost because of fears of being out priced by their competitors offering much cheaper non-compliant or barely compliant alternatives. You could of course ask yet again what price do you put on a life and word is that architects, specifiers and key building owners such as housing associations are no longer prepared to take the risk. Manufacturers such as Proteus Waterproofing have invested in high end fire rated felts in a serious way and these could well find that they begin to dominate the market in areas where quality and health and safety are paramount. But, it is more likely that no real change will happen until new legislation outlawing felt products that fail to achieve good fire ratings is introduced. Surely - it cannot come soon enough.

Bentonite, a clay substance which is often generated from the alteration of volcanic ash, is renowned for its water absorption. These properties make it a valuable material for a wide range of uses and applications, particularly as a waterproofing material in construction of belowground structures such as basements. Bentonite’s availability in the marketplace in various product forms is well-known - it’s been around for hundreds of years. However, the appearance of natural sodium bentonite in Sika BentoShield MAX LM, a fully-bonded, needle-punched membrane and integrated polyethylene flexible laminate, represents a unique offering. The polymer-modified product, which is applied to external surfaces of belowground structures exposed to ground water, is the only bentonite system that’s BBA-approved to BS EN 1928:2000 standard relating to flexible sheets for waterproofing. Superior The sealing technology of Sika BentoShield MAX LM combines the superior swelling performance of the sodium bentonite with high strength polypropylene geotextiles. The two geotextiles are interlocked by a needle-punching process forcing fibres from the non-woven layer through and beyond the woven layer. This process forms a physical link between the geotextiles and locks the bentonite granules in between, keeping them contained. The system is finished with a polyethylene membrane which is laminated to the back which gives an additional level of protection. Fully Bonded During installation, the woven geotextile layer bonds to the fresh concrete due to the non-woven layer that is pulled through and beyond from the needle punching process. When the polymer-enhanced natural sodium bentonite granules get wet they form a dense waterproof gel protecting the structure. Sika BentoShield MAX LM is designed for use in belowground construction. It differs from other BBA-accredited geosynthetic clay liners as it contains specially formulated polymers to enhance performance in contaminated land with a high salt concentration. As well as basements, it is used in cut-and-cover tunnels, backfilled walls and in a variety of more demanding applications, depending on whether water is to be kept in or out. The seams for vertical applications of many bentonite membranes are vulnerable to failure. Sika BentoShield MAX LM laps, however, are sealed with a tape to provide a watertight solution as well as protect against debris and water intrusion during backfilling the system. The seams on horizontal sections can be lapped and protected with a bed of paste created by mixing BentoShield granules with water. Alternatively, tape can be used on higher risk sites. Secure Sika BentoShield MAX LM can also be post-applied to concrete structures where pre-applying is not possible. The membrane is securely held in place with a robust fixing system. Tested and approved to the latest industry standards, Sika provides a 10-year guarantee or 15 when it is used as part of a dual system from Sika. Sika also provides, free of charge: Full specification and detailing support Sika tool box talk training Site support and inspection Easy to install, flexible and robust, Sika BentoShield MAX LM doesn’t require a primer or protection board. Its ability to mechanically bond with the concrete, which in turn virtually eliminates water tracking in the event of damage, makes it the ideal membrane for belowground structures dependent on retaining long-term watertightness.

From Brent Cross in London to Union Square in Aberdeen, Bluewater in Kent to Kirkgate in Bradford, shopping malls across the UK must not only provide an attractive, modern shopping environment with a good tenant mix, they must provide a secure, high-quality and low maintenance environment. Faced with the worst of Britain’s weather, these large retail spaces have all opted for one building material, mastic asphalt, a waterproofing system which delivers the kind of performance that building owners and modern retailers expect. According to the Mastic Asphalt Council, mastic asphalt remains a long established waterproofing membrane and continues to be the system of choice for many new and existing retail developments across the country. When you consider that at many malls the car park deck and roof are one of the same, it’s absolutely critical that water ingress is prevented – a leak or failure of any kind could have catastrophic results. Structural waterproofing is crucial for the exposed areas of rooftop and multi storey car parks. Without it, water ingress occurs, weakening the concrete structure and corroding the steel reinforcements – which can prove fatal to any building - however, good waterproofing is only part of the story. Any type of car park surface must also be immensely durable to tolerate constant vehicle trafficking. Modern mastic asphalt, developed over years of intensive research, has proven itself superior to many of the expensive systems on offer today. Mastic asphalt offers superb value owing to its longevity and ease of installation. Highly suitable for car park and roofing applications – mastic asphalt is not to be confused with tarmac is a void less blend of bitumen and graded limestone. Though wholly waterproof – it can withstand the heavy passage of vehicles that car park applications require and has high standards of skid resistance. Take the Kirkgate Shopping Centre Car Park in Bradford, a refurbishment where contractors resurfaced 11,000 square metres of the main top deck in just eleven weeks. The area provides the main customer access to the shops below and access was maintained at all times throughout the project, ensuring minimal disruption to traders and shoppers throughout the project. Mastic asphalt has one further advantage over other types of waterproof membrane – it is carbon neutral – a massive bonus for the nation’s retailers, anxious to show their green credentials and, when it has reached the end of its useful life, it can be recycled or used as roof screed, minimising the impact on the environment. Offering such a wealth of benefits, it’s easy to see why mastic asphalt remains the first choice for so many shopping centres that are not prepared to risk anything else.

One of the world’s oldest and most traditional waterproofing materials, mastic asphalt is a truly versatile performer, outlasting other materials and proven time and time again on everything from sealing dams to flooring, flat roofs to sports facilities, walkways to balconies and car parks to bridges. Successfully used to provide unbeatable protection from water penetration for centuries, in recent years mastic asphalt has been reformulated to include advanced polymers for increased durability, combining its traditional strengths with modern technology. Mastic asphalt is highly resistant and robust enough to withstand all types of weather situations and attacks from thermal shock (rapid temperature changes), which are a frequent source of break down in many other types of membrane.It’s also non-toxic and non-flammable. Its durability and seamless application means that it is one of the few membranes able to handle consistent heavy foot and vehicular traffic, including from Heavy Goods Vehicles, and still maintain its waterproof integrity. With no application too tricky, it is also easy to repair should alterations or damage occur. Another major advantage with mastic asphalt is that it can be laid at speed, reducing the project costs significantly. It also cools very rapidly, allowing foot traffic within two to three hours, dependent upon ambient temperature. Providing such excellent wear against the extremes of weather – and with a life expectancy of 50 years and more - the waterproof membrane is fast becoming the material of choice for a manner of different buildings including, schools, offices, shopping centres, hotels and even churches. Mastic asphalt has one further advantage over other types of waterproof membrane – it is carbon neutral – a massive bonus for any building owner anxious to show their green credentials and, when it has reached the end of its useful life, it can be recycled or used as roof screed, minimising the impact on the environment. Highly cost-effective, mastic asphalt offers lower installation costs than many other types of membrane. Its versatility makes it the ideal choice, so whether it’s a 31 mile bridge in Hong Kong or St Paul’s Cathedral, this market- leading product is revered across the world.

The flat roofing industry along with most areas in construction, has tried very hard in recent years to paint itself as green. It has been an uphill struggle, particularly for those involved in waterproofing who have traditionally used bitumen based products, resins and other chemical additives to produce products that are proven to work but are not necessarily considered to be environment friendly. Somewhere in the middle there has been a trade off with building owners not prepared to risk using alternative types of waterproofing but who are more than happy to accept that the industry is at least trying to be a little greener. It has led to a whole range of what many critics call “greenwash” initiatives such as carbon offsetting where companies buy into environment friendly schemes in the third world to offset emissions in the west. While such schemes might have created a warm feeling for some it did little for climate change and did nothing to alter the fact that bitumen based products, while probably remaining amongst the best type of waterproofing available, would never be the first products of choice for specifiers with green aspirations.. But that could all be about to change thanks to a remarkable initiative by Proteus Waterproofing which has formed a unique partnership in the UK to supply bitumen roofing felt manufactured in Switzerland that really does tick some, if not all of the green boxes. Ok, so let’s get the bad news out of the way first. Pro Felt from Proteus is still traditional roofing felt, manufactured using bitumen and on face value no more environment friendly than any other felt – but it has one huge advantage over all of its competitors – it is manufactured totally using 100% green renewable energy. Hydro and solar energy are used exclusively to manufacture Pro-Felt in Switzerland significantly reducing its impact on the environment which means that Proteus can truly claim that its felt has significantly higher levels of green credentials than any similar product of its kind. No roofing felt can of course ever claim to be totally green but if specifiers, building owners and contractors are serious about trying to prevent climate change then, at the very least, they should choose a waterproofing product such as Pro-Felt – greener than the rest and a step in the right direction.

There is no doubting the fact that we are living in a global economy and that we are all going through an intense period of change. For many of us, our focus is on our immediate vicinity and surroundings and the issues that affect our customers and business operations. However, there are a number of fundamental issues that affect and drive us all, the world over – financial stability, safety, environmental concerns etc. One area that can directly affect these issues, and more, is innovation. For most manufacturers, innovation is a critical factor that is equated to their success. It builds competitive advantage and in turn financial stability. It can also improve environmental performance and health and safety, criteria that are at the very heart of many businesses’ operational ethos. In many instances, product innovation is developed at a local level, often as a result of customer demand or identification of an opportunity. Some innovations are developed at a global level but this poses great challenges with regards to local interpretation, market need, performance expectations and regulation differences. Factors that drive product specification can greatly differ from one country to another, due to issues such as legislation, climate, culture and infrastructure. As a leading manufacturer of products working across multiple industry sectors (see http://bit.ly/2o8Ca6Z) Sika has a robust – and shared – approach to product innovation. The company has created a number of Global Technology Centres. These centres are design to drive product innovation at both local and global level. The UK centre, based at Sika’s Head Office in Preston focusses on liquid applied membranes and coatings, utilising the vast experience that Sika UK has within this field. Whilst developing products for the UK market, the centre can call upon global market intelligence and the resources of the rest of the group. This helps to advance product development within a network that has the ability to share outcomes and successes around the world, often in turn helping to drive other innovations. In so doing, Sika is able to leverage the benefits of both centralised and decentralised approaches to Research and Development, responding to local market and customer demands and sharing this advancement around the world. For organisations such as Sika, successful innovation results from the inter-connected nature of broad knowledge networks and the sharing of know how within these networks. A great example is the recent development of extremely low odour, liquid roof waterproofing systems. Conventional products have traditionally contained significant quantities of organic solvents that can lead to significant odours during application.

By Talk. Build There is no doubting the fact that we are living in a global economy and that we are all going through an intense period of change. For many of us, our focus is on our immediate vicinity and surroundings and the issues that affect our customers and business operations. However, there are a number of fundamental issues that affect and drive us all, the world over – financial stability, safety, environmental concerns etc. One area that can directly affect these issues, and more, is innovation. For most manufacturers, innovation is a critical factor that is equated to their success. It builds competitive advantage and in turn financial stability. It can also improve environmental performance and health and safety, criteria that are at the very heart of many businesses’ operational ethos. In many instances, product innovation is developed at a local level, often as a result of customer demand or identification of an opportunity. Some innovations are developed at a global level but this poses great challenges with regards to local interpretation, market need, performance expectations and regulation differences. Factors that drive product specification can greatly differ from one country to another, due to issues such as legislation, climate, culture and infrastructure. As a leading manufacturer of products working across multiple industry sectors (see http://bit.ly/2o8Ca6Z) Sika has a robust – and shared – approach to product innovation. The company has created a number of Global Technology Centres. These centres are design to drive product innovation at both local and global level. The UK centre, based at Sika’s Head Office in Preston focusses on liquid applied membranes and coatings, utilising the vast experience that Sika UK has within this field. Whilst developing products for the UK market, the centre can call upon global market intelligence and the resources of the rest of the group. This helps to advance product development within a network that has the ability to share outcomes and successes around the world, often in turn helping to drive other innovations.

Time is money in every area of construction – get it wrong and budgets quickly turn to overspend resulting in disgruntled clients and contractors, but there are some things that you simply cannot rush – or that’s what some experts used to think. New concrete which is part of every new build and refurbishment takes 28 days to cure and conventional wisdom will tell you to forget about installing any type of protective membrane during that time. Until a building is properly waterproofed few trades can start work leading to increased costs, frustration and delays – or that used to be the case – but thanks to a new type of membrane it looks like things are going to change. Cold-Melt® from Proteus Waterproofing is so tough that once installed it is BBA certified to last the life time of the building and can be used to cover green concrete or damp surfaces in just three days. The membrane could return huge savings in reduced labour costs and time on site and could even make all other types of membrane obsolete as contractors and building owners switch from more established products. Experienced contractors will of course say they have seen all these kind of developments before and suggest that a product such as Cold-Melt®, will simply take its place alongside its competitors in the normal course of events. That could well be the case, but if the project demands a warm roof application – a significant sector within the flat roofing market – then Cold-Melt® is going to be difficult to beat. For a start there is nothing else quite like it on the market and because it ticks every box for specifiers and building owners, then it is almost impossible to find a direct competitor. As the name suggest the membrane is cold applied, is odour free so can be used in confined spaces and offers a two layer installation which means a deck can be waterproofed the same day allowing other trades into work, before the top waterproofing layer is applied later. It is going to change the face of flat roofing and could be one heck of a wakeup call for the rest of the industry – when building owners finally realise the potential – and they will.

With our cities bursting at the seams due to lack of space, older buildings and homes are continually being redeveloped to add usable space and maximise investment returns. As a result, the conversion of dank cellars and dingy basements into habitable mega-rooms or below ground offices represents a relatively pain-free way of adding space without the need for planning permission. The problem is when it comes to excavating basements, a great deal of water can often be present. But this shouldn’t be a reason to give up, especially for the installer. Up to 95% of all untreated basements suffer water intrusion at some time, from minor damp to total flooding. When you consider that three quarters of all building failures are attributed to water ingress, the best defence is to get the specification right first time with a high performance waterproofing solution that meets and exceeds industry best practice. The ideal below ground waterproofing solution is one that prevents water penetration entirely and guards against any future failure. Using a high performance internal tanking system, water ingress can be prevented with one relatively simple application. One solution that has a proven track record and has been successfully used for more than a 100 years is the Sika 1 Pre-bagged Waterproofing System. This proven waterproofing solution ensures that specifiers meet the requirements of a project with just one system and it requires no ongoing maintenance. Many homeowners and landlords come to us asking for advice on what to do with their big old, empty basements. Extending a building or moving a business can be extremely costly and stressful these days, so by installing the Sika 1 tanking system to make these damp basements into fully habitable rooms and office space is a much easier and cost-effective option with minimal disruption to the customer. A pre-bagged render system, Sika 1 comprises a blend of kiln dried specially graded aggregates and cements and a liquid waterproofing admixture. The admixture is mixed into the render and bonds monolithically to the prepared substrate, blocking all gaps and capillaries, providing an impregnable and invisible seal. It essentially becomes at one with the structure. One of the big benefits with the Sika 1 system is that it can be used for so many projects. We have installed the Sika 1 system on car parks, public and private swimming pools, containment bunds, lift pits, basements, tunnels, nuclear power plants and many more. Sika 1 is the proven solution for keeping water both in and out.. A crucial part of installing the system is to prepare the substrates correctly and choosing the right method for the substrate. We mainly use scabbling shanks and guns or grit blasting machines for walls and soffits. Floors are usually prepared by Von Arx machines. All areas must be fully washed down after the preparation is complete and again directly before application commences. The pre-bagged mortars and liquid make it easier to get the materials to where you are working and also gives you and the client the security that the mixes are consistent. Anyone who is a waterproofer knows how challenging it can be when you get a project that is a ‘wet one!’ Turning up to start a project when water is gushing through the substrate, breaking the hydrostatic pressure down and then finally seeing it turned into a completely dry space, is very rewarding indeed.

One of the world’s oldest and most traditional waterproofing materials, mastic asphalt is a truly versatile performer, outlasting other materials and proven time and time again on everything from sealing dams to flooring, flat roofs to sports facilities, walkways to balconies and car parks to bridges. Successfully used to provide unbeatable protection from water penetration for centuries, in recent years mastic asphalt has been reformulated to include advanced polymers for increased durability, combining its traditional strengths with modern technology. Mastic asphalt is highly resistant and robust enough to withstand all types of weather situations and attacks from thermal shock (rapid temperature changes), which are a frequent source of break down in many other types of membrane.It’s also non-toxic and non-flammable. Its durability and seamless application means that it is one of the few membranes able to handle consistent heavy foot and vehicular traffic, including from Heavy Goods Vehicles, and still maintain its waterproof integrity. With no application too tricky, it is also easy to repair should alterations or damage occur. Another major advantage with mastic asphalt is that it can be laid at speed, reducing the project costs significantly. It also cools very rapidly, allowing foot traffic within two to three hours, dependent upon ambient temperature. Providing such excellent wear against the extremes of weather – and with a life expectancy of 50 years and more - the waterproof membrane is fast becoming the material of choice for a manner of different buildings including, schools, offices, shopping centres, hotels and even churches. Mastic asphalt has one further advantage over other types of waterproof membrane – it is carbon neutral – a massive bonus for any building owner anxious to show their green credentials and, when it has reached the end of its useful life, it can be recycled or used as roof screed, minimising the impact on the environment. Highly cost-effective, mastic asphalt offers lower installation costs than many other types of membrane. Its versatility makes it the ideal choice, so whether it’s a 31 mile bridge in Hong Kong or St Paul’s Cathedral, this market- leading product is revered across the world. By Mastic Asphalt Council.

A new kind of waterproof membrane – BBA certified, green, seamless and so tough that it is guaranteed to last as long as the building on which it is installed – is set to revolutionise the roofing industry. It’s called Cold-Melt®, exclusively from Proteus, and it makes all other waterproof membranes look obsolete. Cold-Melt® is the waterproof membrane that ticks every box. It is manufactured from recycled rubber crumb and other environment friendly materials such as castor oil and other organically grown products to create an elastomeric, cold applied membrane. It is, as the name implies, installed in a similar way to Hot-Melt and Mastic Asphalt applications, offering the same seamless advantages without the use of molten material or naked flame at roof level. And unlike hot applied membranes, the Cold-Melt® system offers instant waterproofing using a reinforced self-adhesive layer – which can last for several months unprotected – to allow other trades to get to work before the final coat is applied. Cold-Melt® – versatile fast odour free application The Cold-Melt® system from Proteus Waterproofing can be designed as a paved, ballasted, green or brown roof. The membrane does not become brittle with age and when protected from UV exposure, it is certified to last the life of the building. Cold-Melt® exhibits no odour and can be applied in confined spaces for a wide range of applications, offering numerous benefits for both the installer and client due it being 100% solids. As an inverted roof application, it offers a wide range of applications on decks including Concrete, Asphalt, Timber/Plywood and Metal. Ideal for New Build Balcony inverted roof applications where there may be poor access and awkward to get to areas with tricky detailing. Its seamless application ensures that roof detailing is not a problem to help deliver the perfect roof – every time. Cold-Melt® ready to go over green concrete in just three days Cold-Melt® can be used to cover green concrete after three days or over damp surfaces –as opposed to 28 days for many other types of membrane. It is a two layer process: The first layer, Pro-Carrier membrane SA, is a self-adhesive bituminous waterproofing membrane that forms a barrier against vapour and gases which is laid over a pre-primed surface. It comprises a self-adhesive, low thickness bituminous compound which is self-protected by an aluminium film. It also features glass fibre and polyester reinforcement to provide excellent puncture resistance. It is applied to provide a reinforcing layer to all areas receiving the Cold-Melt® application and offers instant waterproofing. The Cold-Melt® membrane can be trafficked once cured for applications such as balconies or podium decks prior to being covered by insulation, ballast and other materials to complete the inverted roof.

It’s an age old substance but bentonite clay has been used for waterproofing for centuries. With characteristics such as binding, cohesion and sealing, bentonite can expand and contract an infinite number of times and is capable of absorbing ten to fifteen times its own weight in water. Swelling up to 15 times its normal dry volume, the clay becomes a highly efficient sealing medium which is one of the principal reasons why it has become the ideal material for the safe sealing of concrete structures. Established construction product First used to help seal earth dams and line ponds in the late 1920s, it went on to be a useful lubricant for driving pilings and caissons. By the 1960s, bentonite became accepted as a below-ground waterproofing membrane for the building construction industry. It can be used under both structural and non-structural floor slabs, below ground foundation walls, between slab applications, and along tunnels and subway walls. Unique sealing solution It’s not just the inherent properties within this clay that make it so effective for waterproofing, but when you combine this with geotextiles, an integral and unique part of Sika Bentonite systems, it’s easy to see why it can offer designers the confidence in the long term performance of the seal, and reduces the risks and costs associated with post-construction repairs and maintenance of leaking structures. Maximising performance For basements and other below ground structures that are exposed to aggressive ground conditions and stress, the Sika Bentoshield MAX LM system combines the unique sealing technology of sodium bentonite with high strength polypropylene geotextiles. Easy to install, its ability to self-heal is unmatched by other bituminous, paint-on or plastic waterproofing methods. It can even swell and seal the pores, cracks and voids in concrete that might be invisible to the naked eye. Whether you want to keep the water in or out, bentonite waterproofing systems are proven on new and remedial waterproofing projects worldwide, preventing the penetration of water and subsequent attack by whatever chemical substances might be present in the surrounding soil.
