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.
Greencore USA offers a full line of high-quality, high-yield and environmentally friendly cementitious building materials. All of the mortars, stuccos and grouts from Greencore USA, a QUIKRETE® company, are manufactured using a unique combination of slag cement and Portland cement to increase the environmental benefits on a project while improving productivity and reducing labor costs.
