Needle-Punched Geosynthetic Clay Liner

Needle-Punched Geosynthetic Clay Liner

Product Introduction：

Bentonite waterproof blanket is a new type of geosynthetic material. The blanket waterproof sheet is made by fixing the bentonite particles between the geotextile and the plastic woven cloth by needling process, which is mixed with the bentonite particles and the corresponding admixtures as raw materials. Bentonite waterproof blanket not only has the characteristics of geotechnical materials, but also has waterproof (seepage) performance. Bentonite waterproof blanket, as a new type of environmental protection and ecological composite impermeable material, has been widely used in water conservancy, environmental protection, transportation, railway, civil aviation and other civil engineering for its unique anti-seepage performance. It is commonly used in the foundation treatment and sealing of landfill sites, the seepage prevention of artificial lakes, reservoirs, channels, rivers, roof gardens, and the seepage prevention of underground buildings such as basements, subways, tunnels, and underground passages.

Product Advantages:

Compactness - Sodium bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its water permeability is equivalent to 100 times the compactness of 30cm thick clay, and it has a strong self-water retention performance.

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 durable.

Short construction period - Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Just use bentonite powder and nails, washers, etc. to connect and fix. No special inspection is required after construction, and it is easy to repair if waterproofing defects are found. GCL has the shortest construction period among existing waterproof materials.

Green environmental protection - Bentonite is a natural inorganic material, harmless and non-toxic to the human body, with no special impact on the environment, and has good environmental performance.

Product Features:

With excellent waterproof and impermeable performance, impermeable hydrostatic pressure can reach 1.0MPa or more, permeability coefficient 5×10 ⁻⁹cm/s Bentonite is a natural inorganic material, will not undergo aging reaction, and has good durability; it has no adverse impact on the environment.

With all the characteristics of geotextile materials, such as isolation, reinforcement, protection, etc., the construction is simple and not limited by the construction environment temperature, and can also be constructed below 0 ℃ During construction, just lay the waterproof blanket on the ground, fix it with nails and washers when constructing the facade or slope, and lap it as required.

Easy to repair: Even after the completion of waterproof (seepage) construction, if the waterproof layer is accidentally damaged, as long as the damaged part is simply repaired, the perfect waterproof performance can
