Topcoat Specialist Coatings can provide a wide range of solutions for your particular environment.  Areas include but are not limited to, carpark decks, patios, internal gutters, roofs, block & concrete walls, water tanks and tunnels. 

We are able to provide effective solutions utilising two-part polyurethane resins for water cut-off and geotechnical applications in many key areas, including tunnels, water structures and sewers, utilising a single-shot, hydrophobic polyurethane.  This system only reacts when it comes into contact with water, producing a semi flexible polyurethane foam. 

Typical applications:

  • Sealing against water ingress
  • Sealing against leaking cracks and joints
  • Void filling
  • Back grouting


  • Potable water approved
  • Can withstand high hydrostatic pressure
  • Variable reaction times
  • Solvent free and environmentally safe
