World-class waterproofing solutions

World class waterproofing

Easy-to-apply, versatile products to cover these challenging areas.


Ideal for waterproofing a flat roof, balcony or terrace, curved roof, guttering and downpipes, Aquaflex Roof is a ready-to-use, flexible, liquid membrane containing fibres for applying continuous waterproofing layers on exposed external surfaces. It is available through Mapei South Africa and is conveniently offered in 20kg drums.

This versatile product can 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 ultraviolet (UV) radiation, and provides long-lasting protection for the substrate.

Where the attention is focused on the sustainable thermal efficiency of a building, the Aquaflex Roof HR solution offers a high Solar Reflectance Index (SRI) value of 105. The white, fibre-filled liquid membrane lowers the surface temperature of the roof by more than 50% compared to a dark-coloured covering. This contributes to a building’s Green Star SA rating by reducing the heat island effect of roofs.

For any waterproofing job to be successful, 90% of the attention needs to be paid to 10% of the area: The corners, joints, cracks and 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 areas that are difficult to seal.
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. It adheres 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 joints between different types of materials such as bitumen membranes, metal, ceramic and cementitious screeds, as well as closing these hard-to-reach fillets between windows and door fittings, ledges and substrates.

In order to seal and waterproof expansion joints and cracks that are subject to movement, Mapei has developed Mapeband TPE to offer the ideal solution to this challenge.

“Mapei’s unrivalled research and development produce 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 as a result.”
