Anti-seepage performance of membrane waterproof blanket
Release time:
2020-11-04
The top layer of the membrane waterproof blanket is a high-density polyethylene (HDPE) film and the lower layer is a non-woven fabric.
The top layer of the membrane waterproof blanket is a high-density polyethylene (HDPE) film and the lower layer is a non-woven fabric. The sodium-based bentonite waterproof blanket with excellent waterproof effect is fixed between the high-strength geotextiles by a special needle punching method, and then the non-woven fabric A layer of high-density polyethylene (HDPE) film is glued on top. Bentonite waterproof blanket has stronger waterproof and anti-seepage ability than ordinary bentonite waterproof blanket. The waterproof mechanism is that the bentonite particles swell in contact with water to form a uniform colloidal system. Under the restriction of the two layers of geotextiles, the bentonite changes from disorder to orderly swelling. The result of continuous water swelling is to make the bentonite layer itself compact. , Which has a waterproof effect.
Physical characteristics of waterproof blanket:
1. It has excellent waterproof and anti-seepage performance, the anti-seepage hydrostatic pressure can reach 1.0MPa or more, and the permeability coefficient is 5×10-9cm/s. Bentonite is a natural inorganic material, which will not cause aging reaction and has good durability; Any adverse effects on the environment are environmentally friendly materials
2. It has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and is not restricted by the construction environment temperature. It can also be constructed below 0°C. Only need to spread the GCL waterproof blanket on the ground during construction, and fix it with nails and washers during vertical or inclined construction, and lap it as required.
3, easy to repair; even after the completion of the waterproof (seepage) construction, if the waterproof layer is accidentally damaged, as long as the damaged part is simply repaired, the perfect waterproof performance can be regained.
4. Relatively high performance-to-price ratio, and very versatile.
5. The product has a width of up to 6 meters, which matches the international geotextile (membrane) specifications, greatly improving construction efficiency.
6. ??It is suitable for the anti-seepage and anti-leakage treatment in the fields with higher requirements for waterproofing and seepage prevention, such as tunnels, subways, basements, underground passages, various underground structures and waterscape projects with abundant underground water resources.
