1. It has excellent waterproof and anti-seepage performance, with an anti-seepage static water pressure of over 1.0MPa and a permeability coefficient of 5 × 10-9cm/s. 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. It belongs to the category of environmentally friendly materials.
2. It has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc., and is easy to construct without being limited by the temperature of the construction environment. Construction can also be carried out below 0 ºC. During construction, simply lay the GCL waterproof blanket flat on the ground. When constructing the facade or slope, fix it with nails and washers, and overlap it as required.
3. Easy to repair; Even after the waterproof (seepage) construction is completed, if the waterproof layer is accidentally damaged, simple repairs to the damaged area can restore the perfect waterproof performance as before.
4. The performance to price ratio is relatively high, and it has a wide range of uses.
5. The product has a width of up to 6 meters, which matches the specifications of international geotextiles (membranes), greatly improving construction efficiency.
6. It is applicable to waterproof and anti-seepage fields with high requirements, such as: anti-seepage and anti-seepage treatment of various underground buildings in tunnels, subways, basements, underground passages, and waterscape projects with rich groundwater resources
7. Product comparison 1. Compared with geomembrane, its advantages are: a. The bentonite waterproof blanket is dense and has good water resistance and waterproof performance. It forms a dense and impermeable gel membrane layer under directional water pressure. Its anti-seepage capacity is 100 times the compactness of 30Cm thick clay. b. Good flexibility, high interface friction coefficient, and able to adapt well to uneven precipitation. c. The construction is simple, and materials can be cut freely when laying. Natural overlapping treatment is used, which can adapt to complex construction sites without the need for professional equipment and personnel. d. Long term waterproof ability, bentonite is a natural inorganic mineral material that will not undergo corrosion and aging. e. The thickness of water absorption is increased several times, making it less prone to breakage. Even in the event of breakage, it has the ability to self repair.
2. The advantage of our company's bentonite waterproof blanket (pad) GCL lies in: a. adopting the most advanced production equipment at home and abroad. Its needle punching is in a disorderly and irregular pattern, preventing the rolling and sliding of bentonite and facilitating uniform absorption. b. Due to the improvement of production equipment, the product width can be adjusted within the range of 2-6m according to engineering needs. c. Due to the increase in width, the overlap area is greatly reduced, which can save materials for users and avoid unnecessary waste. d. Uniform quality, strong impermeability, good flexibility, suitable for uneven settlement of foundation. It can also prevent soil leakage and has good healing ability for defects such as cracks.

Installation Instructions
1. The transportation of bentonite waterproof blankets should prevent exposure to strong sunlight, be waterproof, and moisture-proof. When storing, overhead methods should be adopted, and it is best to use up the bentonite waterproof blanket transported to the site within a few days.
2. When carrying out the next process or adjacent project construction, it is necessary to properly protect the bentonite waterproof blanket that has already completed the construction process to avoid unnecessary human damage.
3. During construction, construction workers should try to avoid walking or stepping on the bentonite waterproof blanket with spiked shoes or high heels, and vehicles and other machinery should not crush the bentonite waterproof blanket.
4. For completed construction, you need to lay a clay protective layer on the same day. For construction that cannot be completed on the same day, it should also be covered to prevent hydration of the bentonite waterproof blanket on snowy or rainy days and strong sunlight exposure.
5. For the waterproofing construction of a single layer of bentonite waterproof blanket, it is necessary to pass the acceptance inspection after the construction is completed. Backfilling should be carried out immediately with soil and sand with a specific gravity greater than 2.0. When backfilling, attention should be paid to preventing damage to the bentonite waterproof blanket. The backfill soil should not contain gravel with a particle size greater than 10mm, and the thickness of the backfill soil should not be less than 30cm. The compaction degree of backfill should not be less than 85%.
