Product Description

Product Description

A blanket like waterproof material made mainly from sodium based bentonite and processed by needle punching, needle punching film coating, or adhesive method. Sodium based bentonite, also known as sodium based montmorillonite, can expand more than 24 times in contact with water and form a very stable gel like waterproof layer through needle punching technology. It has the characteristics of low filtration loss and high viscosity. It is currently a new, environmentally friendly, and ecological waterproof roll materialSodium based bentonite composite waterproof blanket (GCL) is a new type of geosynthetic material. It is a blanket shaped waterproof roll made by mixing graded natural sodium based bentonite particles and corresponding additives as raw materials, and fixing the bentonite particles between geotextiles and plastic woven fabrics through needle punching technology and equipment. Bentonite waterproof blanket not only possesses all the characteristics of geotechnical materials, but also has excellent waterproof (permeability) performance.
The waterproof mechanism is as follows: the sodium based particle bentonite selected for the bentonite waterproof blanket can expand more than 24 times in contact with water, forming a uniform colloidal system with high viscosity and low filtration loss. Under the restriction of two layers of geotextiles, the bentonite changes from disordered to ordered expansion. The continuous water absorption expansion results in the bentonite layer achieving compactness and thus having a waterproof effect

Installation Instructions

Construction precautions:
1. The storage and transportation of bentonite waterproof blankets should be waterproof, moisture-proof, and resistant to strong sunlight exposure. When storing, overhead methods should be used to cushion it, and the bentonite waterproof blanket transported to the site should be used up on the same day.
2. When carrying out the next process or adjacent engineering construction, the completed bentonite waterproof blanket should be properly protected and not damaged by anyone.
3. Try to avoid wearing spiked shoes and high heels to step on the bentonite waterproof blanket; Vehicles and other machinery are not allowed to crush the bentonite waterproof blanket.
4. In the construction of GCL waterproof blanket, the completed GCL should have a 500mm thick clay protective layer laid on the same day; If the construction of the protective layer cannot be completed on the same day, GCL should be covered to prevent it from being hydrated due to rain, snow, and strong sunlight exposure.
5. After the completion and acceptance of the GCL single-layer anti-seepage and waterproofing construction project, soil, sand or stone particles with a specific gravity greater than 2.0 should be used for backfilling. To prevent damage to GCL during backfilling, 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. Backfill soil should be graded and compacted, with a compaction degree not less than 85%.
