Procedure for brickbat waterproofing starts with cleaning the surface with hard material and filling cracks if there are any. Above the clean surface, 2 base coats of waterproofing chemicals are given. Then a 3-4 inch layer of bricks layer is laid on that surface. And the surface is filled with concrete mixture. The mixture is filled in such a way that the surface will have a slope at one side so that water won’t accumulate on the surface and will drain out. And after the drying surface is covered by two coats of waterproofing chemicals.
