KingProof CR100®
Cementitious capillary waterproofing render for concrete.
Overview
KingProof CR100 is a specially formulated single component cementitious crystalline capillary waterproofing system consisting of a blend of cement, fillers, and multiple activating chemicals. When mixed KingProof CR100 produces a brush applied cementitious render. KingProof CR100 prevents the penetration of water by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of the concrete. This crystalline growth reduces substrate porosity and can fill hairline cracks.
Applications
- Waterproofing and protection of:
- Potable water tanks
- Basements
- Bridge decks
- Tunnels Swimming pools
- Sewage tanks
- Retaining walls and foundations
- Underground parking
Advantages
- Works by combining with free calcium in the cement to form insoluble crystals
- Non-toxic system
- Can be applied to moist and green concrete
- Helps the substrate to resist chemical attack over a wide (pH) range, and freeze/thaw cycles
- Excellent adhesion to the substrates
- Durable system and resistant to alkalies
- Becomes an integral part of the structure to which it is applied
- Allows the structure to breathe
- Gives waterproofing effect for positive and negative hydrostatic water pressure
- Ease for application
- Labor cost effective
- STANDARDS KingProof CR100 complies with BS 6920-2.5:2000 as a suitable product in contact with water intended for human consumption with no effect on the public health of the quality of water

Standards & Approvals
Usage & Packaging
KingProof CR100 is available in 25 kg polythene-lined paper sacks.
The coverage obtained will vary depending on the porosity and texture of the surface to which the materials is applied. As a guide, the coverage should be around 1 – 1.5 kg dry powder/m² per coat. A 25 kg bag should be sufficient to cover 17 – 20 m² per c
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature
