Product Overview

Cement based permeable crystalline waterproof coating is a gray powder material formulated by adding active chemical components to ordinary Portland cement as the base material. The cement-based permeable crystalline series waterproof coating mainly adopts a porous waterproof mechanism. Under the action of water, the waterproof coating contains active chemical substances, which use water as a carrier. As water penetrates the structural pores, the active chemical substances penetrate into the interior and react to form insoluble crystals such as ettringite. The active chemical substances react with unhydrated cement particles to promote cement hydration, forming cement hydration crystals, generating a large number of products to fill and seal the pores, preventing water from entering the concrete, thus achieving the waterproof purpose.

Due to its good adhesion, cement-based permeable crystalline waterproof coating does not affect its construction effect on both smooth and rough surfaces, back and upstream surfaces, dry and wet surfaces, or water control surfaces.

Scope of application

Widely used in waterproof construction of tunnels, dams, reservoirs, power plants, nuclear power plants, cooling towers, underground railways, overpasses, bridges, underground continuous walls, airport runways, pile head and foundation piles, wastewater treatment tanks, reservoirs, industrial and civil building basements, roofs, toilets and bathrooms, as well as maintenance and leak prevention of all concrete structure defects in concrete building facilities.

Construction method

Scraping method

Clean up debris and floating mud on the waterproof coating surface, and repair severely uneven concrete surfaces.

Remove and clean the oil stains and debris on the waterproof surface of cement-based concrete structures, then rinse with clean water and apply waterproof materials on the wet base surface during construction.

If serious leakage is found on the base surface, sealing materials should be used for construction first, and then this material should be used to ensure the quality of the project.

The water cement ratio is 0.3-0.4:1, the dosage is 1.4-1.7kg/m2, and the thickness is 1.0mm (+0.05mm) as the standard.

Roll coating method

Roll the material evenly onto the treated surface with a roller brush at a dosage of 1.4-1.7kg/m2.

Gan Sa Fa

Construction shall be carried out immediately after the concrete is poured, compacted, and leveled. Evenly sprinkle the prescribed amount on the surface of the concrete, compact and smooth it in a timely manner. Check for any defective construction areas after final setting and promptly repair them;

Alcohol should be maintained under direct sunlight. Pay attention to spraying evenly and do not cut corners.
