Waterproof blanket

Density: < strong > 1. < / strong > sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is below 5 x 10 ˉ 11 m/s, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.
2 permanent waterproof performance : Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, will not occur aging or corrosion phenomenon, so the waterproof performance is durable.
3 construction is simple: compared with other waterproof materials, the construction is relatively simple, no need to heat and paste. Just use bentonite powder and nails, washers, etc. to connect and secure. No special inspection is required after construction, and it is easy to repair if waterproofing defects are found. GCL is the shortest construction period of existing waterproof materials.
4. Not affected by temperature: will not be brittle in cold weather conditions.
5. Integration of waterproof materials and objects: sodia-bentonite has 20~28 times expansion capacity when it meets water. Even if the concrete structure has vibration and settlement, the bentonite in GCL can repair cracks on the concrete surface within 2mm.
6. Green environmental protection: Bentonite is a natural inorganic material, which has no special impact on the environment and has good environmental protection performance.

  • PRODUCT DETAILS DESCRIPTION

  • Bentonite particles expand when they meet water, forming a uniform colloidal system. Under the restriction of two layers of geotextile, bentonite expands from disorder to order. Continuous water absorption and expansion results in the compaction of the bentonite layer itself, thus having the waterproof effect.
    Anti-seepage principle
    The mineralogical name of bentonite is montmorillonite. Natural bentonite is mainly divided into sodium base and calcium base by chemical composition. Bentonite has the property of swelling in the presence of water. When calcium bentonite expands, its expansion is only about 3 times of its own volume, while sodium bentonite absorbs five times of its own weight in the presence of water and expands to more than 15-17 times of its original size. It locks sodium bentonite in the middle of two layers of geosynthetic materials, playing a role of protection and reinforcement, so that GCL has a certain overall shear strength.
    characteristic
    Density: 1. Sodium base bentonite under water pressure condition to form diaphragm with high density, thickness of about 3 mm, its permeability is below 5 x 10 ˉ 11 m/s, equivalent to 100 times the compactness of 30 cm thickness of clay, have very strong since the water retention performance.
    2. Permanent waterproof performance: Because sodium bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, there will be no aging or corrosion phenomenon, so the waterproof performance is lasting.
    3. Easy construction: compared with other waterproof materials, the construction is relatively simple, without heating and pasting. Just use bentonite powder and nails, washers, etc. to connect and secure. No special inspection is required after construction, and it is easy to repair if waterproofing defects are found. GCL is the shortest construction period of existing waterproof materials.
    4. Not affected by temperature: it will not be brittle in cold climate conditions.
    5. Integration of waterproof materials and objects: When sodium-bentonite meets water, it has 20-28 times expansion capacity. Even if the concrete structure is shaken and settlement occurs, the bentonite in GCL can repair cracks on the concrete surface within 2mm.
    6. Green environmental protection: Bentonite is a natural inorganic material, which has no special impact on the environment and has good environmental protection performance.
    Product features:
    The performance cost is high, the use is very wide. The product range can be up to 6 meters, greatly improving the construction efficiency.
    Application scope and application conditions Applicable to municipal (landfill), water conservancy, environmental protection, artificial lake and building underground waterproof, anti-seepage engineering.
