　　Bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material. Bentonite waterproof blankets come in specifications of 3.5, 4.0, 4.5, 4.8, 5.0, 5.5, and 6.0 kilograms (can be produced according to customer requirements). It is protected by spraying grout on a graded natural sodium based bentonite waterproof blanket to protect the working surface. Bentonite waterproof blanket is a geosynthetic material specially used for artificial lake water features, landfills, underground parking lots, rooftop gardens, water pools, oil depots, and chemical storage yards to prevent leakage. It is filled with highly expansive sodium based bentonite between specially made composite geotextiles and non-woven fabrics. The bentonite anti-seepage pad made by needle punching method can form many small fiber spaces, and the bentonite particles cannot flow in one direction. When encountering water, a uniform and high-density gel like waterproof layer is formed inside the pad, effectively preventing water leakage

　　One; Principle;

　　The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into two categories based on its chemical composition: sodium based and calcium based. Bentonite has the characteristic of expanding when it comes into contact with water. Generally, when calcium based bentonite expands, its expansion is only about three times its own volume, while sodium based bentonite adsorbs five times its own weight of water when it comes into contact with water, and its volume expands to more than 15-17 times its original volume. Sodium based bentonite is locked in between two layers of geosynthetic materials to protect and reinforce GCL, giving it a certain overall shear strength.

　　Two; Physical characteristics:

　　1. It has excellent waterproof and anti-seepage performance, with an anti-seepage static water pressure of over 1.0MPa, a permeability of 5 × 10-11 m/s, and a unit area of bentonite mass of 5kg/m2. Bentonite is a natural inorganic material that does not undergo aging reactions and has good durability; And it will not cause any adverse effects on the environment, which belongs to environmentally friendly materials

　　2. Having all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc., it is easy to construct and not limited by the construction environment temperature. It can also be constructed below 0 ℃. During construction, only theGCL waterproof blanketWhen laying flat on the ground, fix it with nails and washers during facade or slope construction, and overlap it as required.

　　3. Easy to repair; Even after the waterproofing (seepage) construction is completed, if the waterproof layer is accidentally damaged, simply repairing the damaged part can restore the perfect waterproof performance as before.

　　4. The performance price ratio is relatively high, and it has a wide range of applications.

　　5. The product has a width of up to 6 meters, which matches the specifications of geotextiles (membranes) internationally, greatly improving construction efficiency.

　　Sodium based bentonite waterproof blanket, as a new type of environmentally friendly ecological composite anti-seepage material, has been widely used in civil engineering such as water conservancy, environmental protection, transportation, railway, and civil aviation due to its unique anti-seepage performance. Basic treatment and sealing of landfill sites, anti-seepage of artificial lakes, reservoirs, channels, rivers, and rooftop gardens, anti-seepage of famous underground buildings such as basements, subways, tunnels, and underground passages.

　　Suitable for municipal (landfill), water conservancy, environmental protection, artificial lakes, and underground waterproofing and anti-seepage projects in buildings. Construction can still be carried out at negative temperatures (-20 ℃) where traditional waterproof materials cannot be used; Construction can also be carried out on damp substrates (but without visible water); Construction cannot be carried out in rainy or snowy weather; Not suitable for anti-seepage of strong acid and strong alkaline solutions; Due to its inorganic nature, bentonite has better durability than organic waterproof materials
