The Hanson Watertight Concrete system – a waterproofing system integrated into the concrete. Liquid water penetration is stopped by the structure itself and cannot entirely pass through into the structure. The watertight concrete is combined with the appropriate Sika® joint sealing systems for connections, construction and movement joints.
