Sika’s range of bitumen-based coatings are made up of rigid, semi-flexible and flexible waterproofing products. They are supplied as ready to use solutions to seal against damp soil, seepage, percolating water and from damp penetration through brick walls. They must be pre-applied on suitable substrates and are generally post-applied externally or between brick courses on new walls.
Technologies and Advantages for Bitumen Liquid Waterproofing
Bitumen-based coatings 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
Typical Projects:
- Domestic applications
- Residential buildings
- Industrial buildings
