Product Description
Laminated sodium based bentonite waterproof blanket, with a top layer made of high-density polyethylene (HDPE) film and a lower layer made of non-woven fabric. The bottom layer of impermeable sodium based bentonite is made of woven fabric. Fix the sodium based bentonite with excellent waterproof effect between high-strength geotextiles using a special needle punching method, and then apply a layer of high-density polyethylene (HDPE) film on the nonwoven fabric. Bentonite waterproof blankets have stronger waterproof and anti-seepage capabilities than ordinary bentonite waterproof blankets. The waterproof mechanism is that the bentonite particles expand when they come into contact with water, forming a uniform colloidal system. Under the restriction of two layers of geotextiles, the bentonite changes from disordered to ordered expansion. The continuous water absorption and expansion result in the bentonite layer becoming dense and thus having a waterproof effect.
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.
