Fully-bonded waterproofing system for below grade concrete structures

SikaProof® A is an innovative waterproofing system that prevents any lateral water and migration between the waterproofing membrane and the structural concrete. SikaProof® A is typically used to waterproof all types of reinforced concrete basements and other below grade structures. Typical applications include residential, commercial and industrial buildings such as housing, commercial, retail, and public buildings, stadiums and leisure facilities, industrial and manufacturing plants, warehouses and much more. This waterproofing system is ideal for slabs-on-ground, foundation walls and precast concrete elements.

 

Sika Grid Seal Technology: Technology geared towards waterproofing

It consists of a special sealant that is factory applied in a grid-pattern, which creates “mini watertight compartments”. This sealant grid seals and blocks any lateral water migration, 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 is also embedded completely into the fresh concrete and creates a full and durable mechanical bond between the FPO membrane layer of SikaProof® A and the cured concrete.
