Externally applied systems with or without crack-bridging abilities. Sika waterproof mortars and bitumen based coatings are rigid or semi-flexible waterproofing products. They are supplied as ready to use solutions to seal against damp soil, seepage and percolating water. They must be pre-applied on suitable substrates under new structural concrete slabs and are generally post-applied externally on new walls.

They must be used in combination with appropriate joint waterproofing systems for construction and movement joints. Good external drainage with a permanent dewatering system is also necessary; normally using drainage pipes placed at or below the level of the base slabs to prevent any build-up of water pressure.

Use
  • As a waterproofing system for Grades 1 to 2
  • To protect structures against percolating water
  • For limited ground conditions (no settlement, less aggressive environments, low water pressure)
Main Advantage
  • Cost efficient solution (Material + Application)
  • Ready to use & easy to apply
  • Provide additional concrete protection
