Sika's solutions cover the full range of technologies used for below-ground waterproofing: flexible membrane systems, liquid applied membranes, waterproofing admixtures for mortars, joint sealants, waterproofing mortars, injection grouts and coatings.

Key market segments include basements, underground parking garages, tunnels and all types of water-retaining structures (for example reservoirs, storage basins, storage tanks). Watertight systems are faced with more stringent requirements regarding sustainability, easy application and total cost management. Therefore the selection of appropriate waterproofing systems according to the needs and requirements of the owner as well as the detailing of the solution are key for long-lasting and watertight structures.


One of the most recently launched solutions is the innovative SikaProof® below ground waterproofing system. This fully bonded system consists of a highly flexible polyolefin membrane with a unique grid pattern of sealant and a specially designed non-woven fleece. The full mechanical bond effect emerges when the fleece is completely embedded in the fresh concrete.

In addition, the sealant grid prevents any lateral water underflow between the membrane and the concrete as the grid-pattern creates small watertight compartments. The highly durable SikaProof® system is fast and secure to install which results in long-lasting, cost efficient waterproofing
