Permacolour Crystal Seal is a ready-for-use (simply add water) cement-based waterproofing slurry. It consists of a blend of cement, graded quartz and active chemical constituents. It is supplied as a fine, grey powder. The material waterproofs sound concrete or a cement surface against dampness, groundwater and hydrostatic pressure.
Permacolour Crystal Seal is an economical, easily applied method of providing a permanent waterproof barrier on concrete, cement, plaster and cement brick surfaces. It may be used on both new and existing structures on either the wet or the dry side.
- Supporting Walls
- Sewage Plants
- Underground Structures
Since the crystal seal system is based on a chemical reaction taking place inside the concrete, some moisture penetration can be expected until voids are sealed by the crystallization process.
