Fully bonded tanking membrane for below ground structures.
A fully bonded tanking membrane for waterproofing reinforced concrete basements and other below ground structures. Typical projects are residential and industrial buildings such as housing, commercial, leisure facilities, manufacturing plants and warehouses. Engineered structures, such as retaining walls, tunnel galleries, potable water tanks, waste water storage treatment structures and tanks, can also be waterproofed externally.
SikaProof® A can be used in different ground conditions including various levels of groundwater from damp soil, to percolating water or water under hydrostatic pressure. Additionally it can be exposed to different levels of other aggressive conditions.
SikaProof® A consists of an embossed, highly flexible polyolefin membrane, with a special grid pattern of sealant which creates 'mini watertight compartments'. This sealant grid seals and blocks any lateral water underflow, even in the event of any local damage to the membrane. The sealant grid itself is also protected by the specially designed fleece that is laminated into the grid sealant. This fleece forms a full and durable mechanical bond between the SikaProof® A membrane and the hardened concrete.
The SikaProof® A membrane has a self-adhesive strip along one side to allow laps to be formed and sealed. End joints and details are formed using SikaProof® adhesive strips and tapes.
