TRUBUILD AQUALOCK is a two-component, acrylic-modified cementitious waterproof coating designed to provide a flexible, seamless, and durable waterproof barrier on concrete and masonry surfaces. Supplied as a ready-to-mix liquid and powder kit, it forms a protective membrane that helps prevent leakage, seepage, dampness, and moisture-related damage in residential, commercial, and infrastructure applications.

A major advantage of this system is its ability to perform under both positive and negative hydrostatic pressure conditions, making it suitable for exposed and below-ground waterproofing applications. It can be applied using a brush or trowel and even works on properly prepared damp substrates without requiring additional water during mixing.

The coating offers excellent adhesion to concrete and masonry, flexibility for minor structural movement, and resistance to water penetration. It is also non-toxic, low VOC, and CFTRI certified, making it suitable for water-retaining structures such as tanks and reservoirs.
