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.
