Hanson watertight concrete

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.


  • Integral waterproofing solution
  • Strong water reduction, resulting in higher density, durability and strength performance
  • Reduced water penetration under hydrostatic pressure
