Material waterproofing is to rely on building materials to block the passage of water in order to achieve the purpose of waterproofing or to increase the ability to resist leakage, such as waterproofing of membranes, waterproofing of coatings, rigid waterproofing of concrete and cement mortar, and waterproofing of clay and lime.
What is a waterproof material?
First, based on cement waterproof material
There are two types of cement-based waterproof materials, one is general GS waterproof material, and the other is flexible JS waterproof material.
1.General waterproof material
After the general waterproof material is brushed, the coating is formed on the surface to be waterproof and can penetrate the inside of the material. Its crystal can prevent water from passing through and achieve double waterproof effect. General waterproof materials have good bonding properties, and are suitable for waterproofing indoor and outdoor floors and walls.
2.Elastic waterproof material
The flexible waterproof coating has a layer of highly elastic waterproof membrane. The highly elastic waterproof membrane can bond the concrete and cement mortar well, and can be firmly combined with the substrate to achieve the waterproof effect. The flexible waterproof material has good flexibility and can withstand slight vibration and a certain degree of displacement. Is a new type of green environmental protection product, mainly suitable for civil engineering construction environment.
Composite waterproof coating is a new type of green environmental protection product with durability advantages. It is a water-based paint, non-toxic and harmless, and has good environmental performance. Has strong tensile strength, crack resistance and water resistance. It can be directly applied to the wet base surface, with strong adhesion, convenient construction, convenient operation, and applicable. The roof can be immediately waterproofed after the rain.
Three, acrylic coagulation waterproof material
Acrylic waterproof material is listed as a key product of the Ministry of Construction, which has good anti-seepage, durability, waterproof and anti-corrosion effects. It is a polymer modified polymer waterproof and anticorrosive system, which is made of imported materials and domestic high-quality accessories. It is suitable for civil buildings, basements, internal and external walls, water towers, tunnels, toilets, special roof waterproofing components.
Fourth, polyurethane waterproof coating
Polyurethane waterproof coating is a one-component waterproof coating, suitable for wet and dry substrates. It has strong adhesion to the substrate, can penetrate the fine seams of the substrate, has good flexibility, has a strong adaptability to the expansion or cracking of the substrate, high tensile strength, green environmental protection, non-toxic and tasteless. The human body is harmless. Aging resistance, oil resistance, good abrasion resistance, acid and alkali resistance, various colors can be configured according to needs.
