Cementitious Membrane Waterproofing Systems for Lasting Concrete Protection.
Cementitious Membrane Waterproofing systems provide durable, cement-based coatings that protect concrete and masonry from water ingress and structural damage. These flexible membranes are ideal for tanks, basements, balconies, flat roofs and retaining walls, delivering seamless protection against moisture and pressure. Easy to mix and apply by brush or spray, they bond strongly to concrete and plaster surfaces. Designed for long-term performance, our cementitious waterproof coatings ensure reliable, cost-effective waterproofing for both new construction and refurbishment projects.
