Cemented waterproofing is the simplest method of waterproofing, materials required are freely available, easy to mix and apply. More recent technologies have also made negative-side applications possible. For maximum protection to be guaranteed, you must expose the entire foundation wall so the bentonite can be applied all across without leaving any area untouched. It must also take place in an adequately confined area to avoid lifting or cracking the concrete slab. When bentonite and water touch, the clay expands its volume and turns into a gelatinous mass. Sheet membranes also pose other limitations. This is one of the factors that cause homeowners to opt for other waterproofing options. In injection grouting waterproofing, a low viscous injection resin for waterproofings application in small to medium infiltration used in bricks, concrete, and other structures like the basement, tunnels, etc. Older bentonite clay systems typically included kraft paper panel boards which are no longer used You can also install a French drain to support your bentonite waterproofing.
