We offer two membrane protection solutions:
- Protecto-Joint Flexible Waterproofing Membranes For Expansion Joints
- Pro-Coat Rubber Waterproofing
Wallbarn offers the solution for fully waterproofing and protecting buried expansion joints, bonding to most surfaces and membranes effectively.
Wallbarn Protecto-joint is a tough, highly flexible butyl rubber membrane used for waterproofing and protecting preformed expansion joints on roofs, car parks and podium decks.
It has an elongation of 1,000%, far higher than many other expansion joint systems on the market, and can tolerate direct contact with hot materials such as mastic asphalt and hot rubber solutions.
Protecto-joint is ideal for buried expansion joints, roof decks and upstand flashings. It is used for trafficked surfaces and sealing joints in decks where continuous movement in the structure occurs. It can even be permanently immersed in water.
Wallbarn Protecto-joint is vulcanized and cannot be welded or heat bonded. It can be used in horizontal-to-vertical applications, or where the joints are irregular or misaligned, extremely effectively. Because it is so flexible, it can be folded and shaped around even complicated details in one seamless layer. Therefore, no weak spots are exposed in the areas where leaks most often appear.
Since installers do not need to continually fix different sections of the material or install pre-cast shapes and shape the rubber bandage, strength and seal are not compromised.
Wallbarn offers a new waterproofing membrane into the UK market, made from recycled material through strategic partnerships with approved contractors only.
Pro-coat is a polyurethane and rubber based compound which is spray applied and solvent free. It was developed for the military and marine industries as an anti corrosion coating; but it is proving equally as useful in the structural waterproofing sector.
Pro-coat delivers a one-coat solution, offering superb performance against water ingress and damp, corrosion, impact and abrasion, vibration and heat variation.
It is extremely tough and flexible, able to withstand vehicular traffic and even military tanks. It can be used roof and structural waterproofing, tanking, bridge decks, expansion joints, car parks and as a hard wearing floor surface for walkways and station platforms.
Pro-coat is a truly sustainable product since half of the material – the rubber crumb component – is made from 100% recycled car tyres. Furthermore, the rubber crumb is made in a special cryogenic process; so by freezing rather than heating the material, less pollution and energy is produced during manufacture, making Pro-coat one of the most environmentally friendly waterproofing membranes on the market.
It is easy and fast to apply using specialised spraying equipment. Very large or awkward areas can be applied without problem.
It is sprayed at 60°C which means it is considerably safer to use than some other super-heated membranes on the market. It is completely solvent free, making it ideal for applications indoors or in confined spaces.
It is very fast to cure, being “dry to touch” within 90 minutes and “dry to handle” within 120 minutes. For even faster curing, UV heat lamps can be used. Providing the substrate is dry when the membrane is applied, once the curing process starts, it will even set in damp or wet weather.
It can be hand applied, and can be produced in a thixotropic version for vertical applications, where it can be applied up to 8mm thick without sagging.
Pro-coat is applied in one seamless coat usually 3-4mm thick; and adheres to many surfaces, including concrete, steel, aluminium, wood, rubber, fibreglass and prepared asphalt.
It is sold in a standard black colour. Shades of dark or light grey, green or red/brown are also available. Mineral or metal granules can be added to provide a non-slip finish, ideal for flooring and walkway construction.
Pro-coat has undergone over 100 independent tests in Europe and Japan on a variety of application criteria. It has Swedish railway, highway and naval approval; it has been approved by both NATO and UK MoD and has IMO fire & gas certification.
In Sweden it has been used as an anti-corrosion coating on the undercarriages of Fast Trains and national rolling stock since 1988 and has never required repair or replacement.
It has been used as a protective layer on gun turrets on Swedish navy decks since 1986 and has never required repair or replacement.
We are currently in the process of gaining a BBA Certificate for construction and waterproofing.
