Lightweight And Durable Bentonite Geosynthetic Clay Liner For Construction
Product Introduction
The sodium bentonite waterproofing mat (GCL) is a new type of geotechnical engineering material with excellent waterproofing performance and wide application fields. It is mainly composed of naturally graded sodium bentonite particles and corresponding additives, which are mixed and fixed by special processes between two layers of geotextile fabrics to form a waterproof mat-type roll material.
Product Properties
1. Excellent anti-seepage performance: sodium bentonite can be highly expanded after water, forming a gel, with a strong anti-seepage ability
2. Simple construction: Because of the light weight and small size of the sodium bentonite waterproof blanket, the construction does not need large machinery and equipment, and can be completed manually, which greatly reduces the difficulty and cost of construction.
3. Strong durability: Sodium bentonite waterproof blanket not only has good waterproof performance, but also has high destructive resistance and durability, and can effectively resist the impact of water erosion and environmental factors.
Product Application
1. Superior anti-seepage performance: Sodium-based bentonite can expand by more than 24 times when encountering water, forming a highly expansive gel, thereby achieving an excellent anti-seepage effect.
2. Environmental protection characteristics: As a new type of environmentally friendly and ecological composite anti-seepage material, sodium-based bentonite waterproof blankets have been widely used in civil engineering such as water conservancy, environmental protection, transportation, railways, civil aviation, etc.
3. Multifunctionality: Sodium-based bentonite waterproof blankets not only have all the characteristics of geotechnical materials but also have good waterproof performance, and are suitable for various underground projects such as landfill sites, artificial lakes, reservoirs, channels, rivers, roof gardens, basements, subway tunnels, underground passages, etc.
4. Simple construction: Due to its light weight and small volume, it is easy to operate and lay during the construction process, greatly improving the construction efficiency.
