Spray-Lock Concrete Protection® manufactures colloidal silica products that enhance and improve concrete performance throughout its service life. Our proprietary technology reacts with available alkali in concrete to fill capillaries and bleed water channels with Calcium Silicate Hydrate (C-S-H). This becomes an integral part of the concrete's matrix, leaving the surface profile unaffected. Simply put, SCP creates more concrete within the concrete's pore structure. When treated with SCP, concrete is able to protect itself against salt, chloride, and chemical attack in the most natural way possible, from the inside out.
