Basecrete® BC-L0545 5 gal Intercept Densifier Colloidal Silicate Densifier. INTERCEPT is a highly penetrating, highly viscous concrete densifier, to be used as the Pool, Shell, Primary, Waterproofing. Upon application, INTERCEPT penetrates deeply into the concrete matrix, on a molecular level, searching and filling out all the voids that exist within any concrete structure. INTERCEPT bonds with the free Calcium and Lime within the concrete, transforming itself into a dense waterproof barrier of colloidal silicate gel. It is important to note that the concrete remains able to “breathe” allowing vapors from within the concrete to escape.
Apply INTERCEPT with a low-pressure pump type sprayer. Apply two coats in quick succession removing excess material immediately. Do NOT allow excess material to dry on surface.
