Waterproof sealant: sealant technologies

Cementitious sealant 

Our cementitious sealants are ideal for working with swimming pools, basements other interior or exterior assemblies composed of tiling or tile-based substrates. We also produce cementitious products that are formulated specifically to combat positive water pressure.

Silyl modified polymer (SMP)

Our SMPs are acid-free and perfect for a wide range of waterproofing needs. Our silylated modified polymers are capable of bonding to the same variety of substrates as a standard silicone sealant, but possess a much higher bond and peel strength.

Bitumen sealant

Our bituminous sealant solutions possess excellent resistance to most salt solutions, water, alcohol, and dilute acids and alkalis. This makes them ideal for waterproofing, particularly for materials used on exterior applications like roofing materials.
