Hanson Watertight Concrete – concrete pore blocker and powder. The powder is a combined water-resisting and HRWR/Superplasticising admixture, used to enhance the  workability and reduce the permeability of concrete. However, joint sealing systems may well be needed for connections and movement joints.

Special features:

*       Integral waterproofing solution, strong water reduction, resulting in higher density, durability and strength performance and reduced water penetration under hydrostatic pressure
