Spray-applied Waterproofing

CWS100® is a modified sodium silicate which is sprayed onto cured concrete. It forms a barrier inside the concrete which waterproofs and protects the concrete for the design life of the structure.

CWS100® reacts with calcium to form a water insoluble calcium silicate hydrate gel, that seals cracks in the concrete up to 2.2mm and will remain reactive in the concrete to seal future hairline cracks, in the presence of water.

Advantages:

  • CWS100® Waterproofs for the life of the structure
  • Permanently seals static cracks up to 2.2mm
  • Seals future hairline cracks on contact with water
  • Protects against water, chloride and sulphate ingress; increases resistance to chemical attack
  • Hardens concrete to the same level as granite
  • Non-toxic. Suitable for potable water
  • No protective screed required
  • Trafficable
  • Simple one coat application. No de-bonding as with membranes
  • Best for parking decks
