KMA is a hydrophilic crystalline admixture used to provide long-term protection of masonry mortars and concrete masonry units against water and waterborne contaminants by reducing permeability and absorption of the mortar. Simplifying installation by removing the need for surface-applied sealers and easily incorporated into the existing mix-design and application processes, KMA provides superior waterproofing performance that lowers building maintenance and repair costs. When added to cementitious mortars or concrete masonry units, KMA chemically reacts with water and unhydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and microcracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing protection.
Manufactured roof-trusses. Integrated circuit boards. Pre-assembled door and frame units. Those are a few examples of what might be called “unitized systems.” In each case, a number of separate components have been factory-assembled into a single unit, ready to be installed quickly and easily. With unitized systems, a job gets done much faster, costs are lower, and skilled workers are freed to focus on the more challenging tasks.
Amerimix Water Repellent Mortar with RainBloc GP is part of the total RainBloc system. When used with concrete masonry units that contain RainBloc, it creates a wall system that has been proven in both the lab and on jobsites to inhibit water penetration, creating a superior moisture barrier.
