World-class waterproofing solutions from Mapei

09 April 2014

Mapei South Africa has well-proven solutions for all waterproofing challenges with its comprehensive range of Mapei waterproofing products. For the past five years, the company’s technical service team has been introducing the local construction industry and DIY homeowner to the benefits of the advanced building technology additives, sealants, adhesives and concrete performance chemicals that are available from the international Mapei Group. Offering market-leading performance and handling advantages, Mapei’s 1400 products are recognised throughout Europe, America and the Far East.

For waterproofing a typical flat roof, balcony or terrace, curved roof, guttering and downpipes, Mapei offers convenience in a 20kg drum in the form of Aquaflex Roof, a ready-to-use flexible liquid membrane containing fibres, for continuous waterproofing layers on exposed external surfaces. The versatile, easy-to-use product may be applied to concrete, ceramic and stone coatings, cementitious screeds, asbestos cement, bitumen sheaths, wood, and even galvanised sheet, copper, aluminium and iron after applying Mapei Eco Prim T primer.

Once dry, Aquaflex Roof is tough enough to withstand occasional light foot traffic, and flexible enough to cope with normal temperature variation expansion and contraction stresses. The product is resistant to all atmospheric conditions and UV radiation, and provides long-lasting protection for the substrate.

Where there is a focus on the sustainable thermal efficiency of a building, the solution is Aquaflex Roof HR, a ready-to-use, fibre-filled liquid membrane with a high solar reflectance index (SRI) of 105. The white-coloured product lowers the surface temperature of the roof by more than 50% compared with a dark coloured covering. This contributes to a building’s Green Star SA rating by reducing the heat island effect of roofs.

For any successful waterproofing job, 90 per cent of the attention needs to be paid to 10 per cent of the area: the corners, the joints, the cracks and the fillets between horizontal and vertical surfaces. Mapei’s research and development into elastic waterproofing systems has produced Mapeband SA, a user-friendly, long-lasting solution for these awkward to seal areas. Mapeband SA is a self-adhesive butyl rubber tape with alkali-resistant non-woven fabric bonded on the outer surface to provide excellent adhesion for the waterproofing membrane that will be applied over it.

Mapeband SA has excellent adhesion to virtually any type of absorbent and non-absorbent substrate and gives immediate protection against heavy rain. Typical applications include waterproofing corners and fillets between walls and floors on terraces, balconies and in bathrooms and showers; sealing the joins between different types of material such as bitumen membranes, metal, ceramic and cementitious screeds; and those hard-to-reach fillets between windows and door fittings, ledges and substrates. The ideal solution for flexibly sealing and waterproofing expansion joints and any cracks that are subject to movement is Mapeband TPE.

“Mapei’s unrivalled research and development produces user- and eco-friendly products that enable us to offer our South African customers world-class solutions for any waterproofing needs,” says Paul Nieuwoudt, Mapei South Africa’s Product Manager for Building Systems. “We can provide an optimum solution for a wide range of structural and environmental conditions and ensure a long service life result.”
