                                    Bentonite Waterproof Blanket

                                    Product description:

                                      The bentonite waterproof blanket is made of high-expansion sodium bentonite filled between the special composite geotextile and non-woven fabric. The bentonite impermeable pad can form many small fiber spaces, so that the bentonite particles cannot flow in one direction. When in contact with water, a uniform and high-density colloidal waterproof layer is formed in the pad, which can effectively prevent water leakage.

                                      Bentonite waterproof blanket products are mainly used in the following aspects:

                                      1. Municipal engineering, underground engineering of subways, buildings and seepage prevention of roof reservoirs.

                                      2. Environmental sanitation, domestic waste landfill, sewage treatment plant, industrial waste. Technical index of bentonite waterproof blanket JG/T 193-2006

                                    NO.

                                    Features:

                                      Cost-effective, very versatile. The product range can reach 6 meters, which greatly improves the construction efficiency.It can still be constructed under negative temperature (-20℃) where traditional waterproof materials cannot be constructed; it can also be constructed on wet base layers (without clear water); it cannot be constructed in rainy and snowy weather; it is not suitable for strong acid and strong alkaline solutions Infiltration; because bentonite is an inorganic material, its durability is better than that of organic waterproof materials.

                                    Quality performance:

                                      The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into two categories: sodium-based and calcium-based according to its chemical composition. Bentonite has the property of swelling in contact with water. Generally, when calcium-based bentonite expands, its expansion is only about 3 times its own volume, while sodium-based bentonite absorbs five times its own weight of water when it encounters water, and its volume expands to 15-17 times its original volume. Above, the sodium bentonite is locked in the middle of two layers of geosynthetics, which plays the role of protection and reinforcement, so that GCL has a certain overall shear strength.

                                    Density: Sodium bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its water permeability is below &×10ˉ11m/sec, which is equivalent to 100 times the density of 30cm thick clay. Water retention properties.

                                    Permanent waterproof performance: Because sodium bentonite is a natural inorganic material, it will not age or corrode even after a long time or if the surrounding environment changes, so the waterproof performance is durable.

                                      Simple construction and short construction period: Compared with other waterproof materials, the construction is relatively simple and does not require heating and pasting. Just attach and fix with bentonite powder and nails, washers, etc. No special inspection is required after construction, and it is easy to repair if waterproof defects are found. GCL has the shortest construction period among existing waterproof materials. It is not affected by temperature and will not brittle in cold climates.

                                      Integration of waterproof materials and objects: When sodium bentonite encounters water, it has an expansion capacity of 20-28 times. Even if the concrete structure vibrates and settles, the bentonite in GCL can repair the cracks on the concrete surface within 2mm.

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