Concrete slab that was previously sealed or covered with torch-on waterproofing. Clean the surface of the slab and make sure it is smooth & free from debris and loose or flaking particles. Delaminated sections of torch-on membrane should be removed before waterproofing.
Use BASE to embed the Armtec Membrane into the concrete slab. Base is a cementitious polymer and is used to achieve the required adhesion to torchon or bitumen surfaces.
The Armtec Mesh is an alkali-resistant glass fibre mesh used to reinforce waterproof protection layers, antifracture membranes and cementitious smoothing and levelling layers.
For a smoother finish, the entire surface can be coated with Cavity Filler before waterproofing is applied. Cavity Filler has extreme adhesion properties to most substrates like tiles, wood and metal, including bituminous systems like touch-on.
Apply 3 to 4 layers of HydroSeal HF over the entire concrete roof slab. HydroSeal HF is a co-polymer, high-performance universal waterproofing membrane specifically developed for long term protection of all types of roof surfaces, concrete roof slabs, parapet walls, tiled roofs, valleys, ridges, vents and flashings.
For highly trafficable areas it is advisable to do the last coat of waterproofing with HydroSeal, which will produce a harder finish than HF.
The Armtec Renew system was used to renew the torchon waterproofing system at a commercial client in Pretoria. The system was renewed with great success and the client was very pleased with the end result.
Failed bitumen waterproofing on a new residential concrete roof slab in Pretoria East was replaced with the Armtec Renew waterproofing system. Extruding roof sections and the chimney was also sealed.
