One must thoroughly understand the dynamics behind the penetration and resultant performance of clear liquid waterproofing materials. As discussed else where in this training manual, Combocrete products feature the exclusive Micro-Lok chemical reactive characteristic. This chemical interaction within the substrate that ultimately acts to repel water is only achieved by 100% penetration of our products into the wall surface. The solids which are dissolved within the liquid solution are carried into the substrate and, of course, the speed in which they penetrate depends entirely upon the density or porosity of the building material.
