What are the commonly used construction waterproof materials?

At present, waterproof materials are mainly divided into two categories:

1. Flexible waterproof materials, such as: various material coils, JS composite materials, polyurethane waterproof materials, waterproof glue and other emulsion polymer waterproof materials. These materials mainly wrap the base surface and do not allow water to seep out and penetrate, and these materials have a certain elongation and tensile ability.

The only drawback is that these materials have a certain waterproof life, that is, waterproof life. These materials are widely used in roofing, toilets, expansion joints, downspouts, masonry and other substrates.

2. Gangsheng waterproof material: as the name suggests, it has high strength, but it lacks elongation and tensile ability, but the waterproof life is the same as concrete after construction, such as: water leakage, cement-based permeable crystallization, permeable waterproofing agent, permanent condensate and so on.

They are the use of the porosity of the concrete structure through the capillary phenomenon, the use of hydrophilicity to water as the carrier to penetrate into the concrete, chemical reaction, the formation of crystals, plugging the capillary pores to achieve waterproof effect, increase the strength of concrete, these materials are widely used in basements, toilets, sewage pools, pools, can also be directly used in drinking water pools and so on. Therefore, now buildings with high waterproof requirements will be designed with a combination of rigidity and flexibility!

The waterproof materials commonly used in construction projects include waterproof membranes, waterproof coatings, sealants, tiles, and other waterproof materials.

1. Waterproofing membranes are divided into asphalt-based waterproofing membranes (ordinary petroleum asphalt or oxidized asphalt waterproofing membranes) and polymer waterproofing membranes (plastic waterproofing membranes, rubber waterproofing membranes, rubber and plastic blended waterproofing membranes).

2. Waterproof coatings are divided into asphalt-based waterproof coatings (water emulsion asphalt-based waterproof coatings, solvent-based asphalt-based waterproof coatings), polymer waterproof coatings (water emulsion polymer waterproof coatings, reactive polymer waterproof coatings) and inorganic waterproof coatings.

3. Sealants are divided into main materials (such as asphalt paste, butyl sealant, polyurethane sealant, acrylic vinegar sealant, silicone sealant, etc.) (such as elastic sealant for windows, weather-resistant adhesive for curtain wall, epoxy sealant for dry-hanging stone curtain wall, silicone structural sealant for construction, etc.).

4. Other waterproof materials, such as grouting plugging materials, waterproofing agents, waterstops, waterproof glue, bentonite waterproof blankets, etc.

Commonly used waterproof materials for construction projects:

One. Bituminous-based waterproofing material.

JC-1 cold-water adhesive compound, neoprene-1 waterproof coating, fish oil modified asphalt coating, etc., all belong to this list. Common water emulsion asphalt coatings, JC-2 cold rubber compounds, waterborne asbestos asphalt waterproof coatings, elastic asphalt waterproof coatings, neoprene latex asphalt waterproof coatings, etc.

Two. Rubber-based and resin-based waterproofing materials:

EPDM membrane, neoprene waterproofing membrane, polyvinyl chloride (PVC) waterproofing membrane, chlorinated polyethylene waterproofing membrane, etc.; Waterproof coatings such as neoprene-hydralam coatings, low molecular weight butyl rubber coatings, silicone coatings and polyurethane coatings.

Three. Powdered waterproof coating:

Developed in the late 80s. It is a powder of inorganic non-metallic raw materials, and its surface is coated with a strong hydrophobic organic polymer material. During construction, the waterproof and heat-insulating powder is spread on the leveling layer, and then a layer of kraft paper is added as the isolation layer, and finally fine stone concrete is added on the isolation layer as the protective layer of the waterproof powder.

Waterproof materials include waterproof coatings, waterproof pastes, waterproof membranes, sealants and other waterproof materials.

In recent years, polymer membrane waterproofing materials are more popular. Polymer waterproof coating is a waterproof material with polymer material as the main body, called polymer waterproof material. Polymer waterproof materials mainly refer to waterproof materials and inorganic waterproof materials that are different from asphalt, commonly used polymer organic waterproof materials and modified asphalt waterproof materials, with excellent high elasticity and excellent waterproof performance, non-toxic, tasteless, very safe and environmentally friendly.

It has strong adhesion performance, will not fall off and cracks, and the polymer waterproof coating has a long service life, is not affected by the environment, can be used in a relatively humid environment, after the moisture slowly dries, it will still maintain the original color color, with very good waterproofness.

However, there are too many polymer waterproof materials on the market now, and the best is uneven, and users can find a professional waterproof company like Keshun shares.

Founded in 1996, after more than 20 years of steady operation and efficient development, Keshun Waterproof Technology Co., Ltd. has grown into a comprehensive building materials company with comprehensive waterproof solutions as its main business, integrating engineering building materials, civil building materials and building repair business sectors, and its business scope covers domestic and foreign countries.
