Overview
Cementitious waterproofing bonds well to damp concrete, is applied simply by brush or trowel and can be tiled or rendered over. Flexible grades bridge small substrate cracks.
Drinking-water tanks need a product certified for potable water contact. The system is usually two coats at right angles with reinforcing mesh at corners and joints.
