Integrated Cementitious Waterproofing Services for Tanks

Cementitious waterproofing is a system based on polymer-modified cement materials, applied to concrete surfaces to form a solid, durable layer that prevents water leakage and resists moisture and salts. It is easy to apply on damp surfaces and bonds well with concrete, making it a reliable choice for waterproofing water tanks, basements, and swimming pools.

For potable water tanks, a product certified for this purpose must be used, following the recommended curing and rinsing period.

Cementitious waterproofing is typically applied in two or more coats by brush or spray, with the recommended drying time observed between coats to ensure a cohesive membrane free of hairline cracks.
