Waterproofing problems solved for engineers / Architects

Problem: Concrete's Leaking
Solution: A chemical approach to solving permanent sealing and waterproofing problems



Chemcure 200, a clear chemical solution applied to concrete in accordance with specifications. This sealant penetrates 20mm deep internally into concrete and undergoes two chemical combinations:

  • Providing a hardened zone of low permeability
  • The ingress of water and chloride ions from salt environments is inhibited

Performing Actions:

Chemcure 200 precipitates two separate chemical reactions; on entering concrete it reacts with lime increasing its hardness.  Further reaction with the lime in concrete creates a polymerised water-displacing thixotrope that pore-blocks the microscopic voids present in concrete, permanently preventing the ingress of water.  This internal approach continues by bridging and sealing hairline cracks up to 3mm and prevents further cracking.


  • Waterproofing concrete structures
  • High traffic areas, factory floors, airport, airways
  • Concrete and block buildings, bricks
  • Dust free and hardening of concrete floors
  • New concrete roofs.
  • Bridges, carparks
  • Old existing roofs, tile roofs water reservoirs, dams, tanks, drinking water vessels
  • Preservation of old existing concrete buildings

(Brick buildings and existing old swimming pools, may require 1 coat Chemseal 400 before and treatment is used.)
