Conplast Crystalline — crystalline waterproofing material for concrete

Conplast Crystalline is a premium crystalline waterproofing material from Fosroc Chemicals India Pvt. Ltd. — a cement-based waterproofing system that can be applied as a surface treatment or used as an integral admixture in fresh concrete to deliver permanent, self-sealing protection against water ingress.

Once activated by moisture, Conplast Crystalline's active chemicals penetrate deep into the concrete matrix, reacting with cement hydration products to form insoluble crystals that permanently seal capillary pores, micro-cracks, and voids. Unlike conventional waterproof coatings, its crystalline action continuously reactivates whenever moisture is present — becoming a permanent part of the concrete structure and providing lifelong waterproof protection.

Widely trusted as a waterproofing chemical for water tanks, basements, swimming pools, tunnels, retaining walls, and foundation slabs across India, Conplast Crystalline ensures strong reliability, user-friendly application, and consistent on-site performance — a dependable construction chemical from Fosroc preferred by applicators and contractors for its proven long-term durability and effectiveness.
