CRYST SLURRY® is a concrete surface applied that becomes an integral part of concrete through a crystallization process, which waterproofs and protects concrete in-depth. CRYST SLURRY® designed to penetrate deeply into the substrate and claws by active crystallization into the pores of the substrate to achieve high protection to the concrete against seawater, wastewater, and many other aggressive chemicals. CRYST SLURRY® retains the crystalizing reaction over the whole working time. When CRYST SLURRY® is applied to either the positive or negative side of the concrete surface, the active material reacts with water and the cement hydration to form nanocrystals. These crystals fill the pores and cracks in the concrete to block any ingress of water (even under pressure). CRYST SLURRY® is used on all new or old structurally sound concrete surfaces and the waterproofing properties stay intact, even if the coating is partially removed or small cracks develop after the application CRYST SLURRY® is suitable for use in water storage tanks, reservoirs, water treatment plants, etc.

Used for all types of waterproofing and concrete corrosion protection in:

  • Below grade: basements, elevator pits, parking structures, and foundations of high-rise towers
  • Water containment: water tanks, Water towers, and storage tanks
  • Waste Treatment Facilities: reservoirs, water treatment tanks, sewage, and manholes.
  • Tunnels, subway systems, and below-grade concrete pipelines.
  • Marine structures, bridges, dams, and highway infrastructure.
  • Swimming pools, decks, bathrooms, garages, and exteriors.
  • Environmentally friendly
  • Applied to old or new concrete.
  • Improves durability of concrete.
  • Effective against extreme hydrostatic pressure from either positive or negative surface of the concrete.
  • Protects against water, chloride, sulfate ingress, and chemical attack.
  • Becomes an integral permanent waterproofing.
  • Penetrates deeply and seals concrete’s capillary tracts and shrinkage cracks.
  • No membrane to tear or puncture.
  • Protects against concrete carbonation.
  • Increases concrete’s compressive strength.
  • Protects reinforcing steel against corrosion.
  • Active crystallization to seal cracks up to 0.5mm wide.
  • Allows concrete to breathe.
  • Does not require a dry surface.
  • Non-toxic – ideal for potable water tanks.

CRYST SLURRY® is available in 20 kg bags or pails.
