Waterproof blankets, especially bentonite composite waterproof blankets (GCL), areAn efficient anti-seepage material widely used in environmental engineering。
Material CompositionIt is mainly made by mixing natural sodium based bentonite particles and corresponding additives, and fixed between geotextile and plastic woven fabric through needle punching process.
main purposeWaterproof blankets are mainly used in waste landfill sites, underground water reservoirs, underground infrastructure construction and other projects to solve sealing, isolation and leakage prevention problems. Due to its excellent performance and resistance to damage, it has been widely used in the fields of environmental protection and engineering anti-seepage.
working principleBentonite is a natural clay mineral with strong expansibility and water absorption capacity. When encountering water, bentonite will expand and the gaps between its particles will decrease, thus forming an effective waterproof barrier under pressure conditions.
Environmental performanceThis material does not contain harmful substances and will not cause pollution to the environment. Its production and construction processes do not generate air and noise pollution, therefore it is considered an environmentally friendly product.
durabilityDue to the physical properties of bentonite, long-term use will not age or weaken its waterproof performance, making waterproof blankets a durable and aging resistant material with a service life that can exceed the design life of building structures.
Installation methodThe installation of waterproof blankets requires following certain procedures and precautions, including material storage, base treatment, laying methods, etc., to ensure that their performance is fully utilized.
