GCL: The blanket-like waterproof material is made of sodium bentonite as the main raw material, and is processed by needle punching, needle punching coating or adhesive method. Sodium bentonite is also called sodium montmorillonite. It can expand more than 24 times when it comes into contact with water and form a very stable colloidal waterproof layer through needle punching process. It has the characteristics of low filtration loss and high viscosity. It is a new, environmentally friendly and ecological waterproof membrane.
Sodium bentonite composite waterproof blanket (GCL) is a new type of geosynthetics. It is made of graded natural sodium bentonite particles and corresponding admixtures as raw materials. It is fixed between geotextile and plastic woven cloth through needle punching process and equipment to form a blanket-like waterproof membrane. Bentonite waterproof blanket has all the characteristics of geotechnical materials and excellent waterproof (seepage) performance.
The waterproof mechanism is: the sodium-based bentonite particles used in bentonite waterproof blankets can expand more than 24 times when exposed to 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 orderly expansion. The result of continuous water absorption and expansion is that the bentonite layer itself becomes dense, thus having a waterproof effect.
Bentonite waterproof blankets can be divided into needle-punched sodium-based bentonite waterproof blankets, needle-punched film-coated sodium-based bentonite waterproof blankets, and adhesive sodium-based bentonite waterproof blankets according to theproduction process.
The needle-punched film-coated sodium-based bentonite waterproof blanket is a layer of high-density polyethylene geomembrane compounded on the outer surface of the non-woven geotextile of the needle-punched sodium-based bentonite waterproof blanket.
Adhesive sodium bentonite waterproof blanket is a sodium bentonite waterproof blanket produced by bonding bentonite particles to high-density polyethylene boards with adhesives and compressing them. As a new type of environmentally friendly ecological composite anti-seepage material, sodium bentonite waterproof blanket has been widely used in civil engineering such as water conservancy, environmental protection, transportation, railways, and civil aviation for its unique anti-seepage performance. Foundation treatment and capping of landfills, anti-seepage of artificial lakes, reservoirs, channels, rivers, roof gardens, anti-seepage of underground buildings such as basements, subways, tunnels, and underground passages.

Composite geomembranes are widely used in channel anti-seepage projects. The extensive application and effectiveness of geosynthetics in civil engineering, especially in flood control and emergency projects, have attracted great attention from engineering and technical personnel. For the application technology of geosynthetics, the state has put forward normative technical requirements in terms of anti-seepage, anti-filtration, drainage, reinforcement, protection, etc., which has greatly accelerated the promotion and application of new materials. This material has been widely used in irrigation channel anti-seepage projects. Combined with construction practice, this paper briefly discusses the application technology of composite geomembranes.
Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or
weaving. Geotextile is one of the new geosynthetics. The finished product is in cloth shape, generally 4-6 meters wide and 50-100
meters long. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.

2. Corrosion resistance. It can resist corrosion for a long time in soil and water with different pH values.
3. Good water permeability. There are gaps between the fibers, so it has good water permeability.
4. Good antimicrobial properties. It is not damaged by microorganisms and insects.
5. Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.
6. Complete specifications: The width can reach 9 meters. It is the widest product in China, with a unit area mass of 100-1000g/m2

Geomembrane liners, specifically those made from high-density polyethylene (HDPE) or reinforced polyethylene (RPE), offer superior performance compared to traditional liner options like clay or concrete. Their superiority stems from a range of advantageous properties, including their impermeability, durability, cost-effectiveness, and ease of installation.
1. Impermeability
One of the most important functions of any liner is to prevent leakage and seepage. HDPE and RPE geomembranes are engineered to be highly impermeable, creating a robust barrier against liquids and gases. Their low permeability rates are far superior to compacted clay liners, which are prone to cracking and shrinking over time. Concrete can also develop cracks due to temperature changes, chemical attack, or settling. In contrast, HDPE and RPE liners provide a continuous, seamless barrier.
2. Chemical Resistance
Both HDPE and RPE liners have excellent resistance to a broad range of chemicals, making them ideal for use in industrial waste containment, mining operations, and agricultural applications. They resist corrosion and degradation even in harsh environments. Conversely, clay can be eroded by certain chemicals, and concrete is susceptible to acid attack and sulfate damage.
3. Durability and Longevity
HDPE and RPE liners are known for their exceptional durability. They are UV-resistant and can withstand extreme temperatures, ensuring long-term stability even under harsh environmental conditions. Their flexibility allows them to adapt to ground movement and settling without cracking. In contrast, concrete and clay liners are more rigid and can crack under similar conditions, reducing their effectiveness over time.
4. Cost-Effectiveness
From a cost perspective, geomembrane liners offer a more economical solution than concrete. HDPE and RPE liners are lightweight, reducing transportation costs. They can also be prefabricated to specific dimensions, simplifying the installation process and minimizing labor costs. Clay and concrete liners typically require extensive site preparation and skilled labor, driving up costs.
5. Ease of Installation
Installing HDPE and RPE liners is relatively straightforward. They can be welded together to form large, continuous sheets with minimal seams, which reduces the risk of leakage. Installation is also quicker compared to laying concrete or compacting clay layers. This ease of installation translates into significant time savings, particularly for large projects.

Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and non-woven fabric. The anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. The plastic films used for anti-seepage at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified asphalt blended geomembrane) is also designed for use in tunnel applications. They are a kind of polymer chemical flexible material with a small specific gravity, strong elongation, high deformation adaptability, corrosion resistance, low temperature resistance, and good antifreeze performance.
