② cement-based permeable crystalline waterproof material

The cement-based capillary crystalline waterproof coating (CCCW) is a powdery rigid waterproof material prepared by using special cement, quartz sand and the like as base materials and permeating various active chemical substances. After the active chemical substances in the material react with water, the active chemical substances permeate into the concrete through carrier water, form water-insoluble dendritic crystals in the concrete, and block capillary channels, so that the concrete is compact and waterproof.

The cement-based permeable crystallization type waterproof coating has a long waterproof effect, is simple and convenient to construct, is suitable for brush coating, roller coating, blade coating and dry scattering construction, can be directly coated during construction, does not need to be leveled on the surface of concrete, can be backfilled 3 days after construction is finished, does not need special protection, and can form a complete whole with the concrete. The permeable crystallization generated by the material can play a role in preventing water in the structure to block the pores of the internal structure of the concrete, can play a role in compensating shrinkage in a coating of a base surface of the concrete structure, can ensure that the constructed base surface of the structure also has good anti-cracking and anti-permeability effects, and has certain self-repairing capability.

③ polyurethane grouting material

The polyurethane grouting material is a high-molecular grouting plugging material synthesized by polymerization reaction of polyisocyanate and polyhydroxy compound. The polyurethane leak-stopping agent can produce chemical reaction after meeting water to form elastic colloidal concretion body, so that it can attain the goal of stopping water.
