Product Description

Geosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives.

Due to environmental laws, any seepage from landfills must be collected and properly disposed off, otherwise contamination of the surrounding ground water could cause major environmental and/or ecological problems. The lower the hydraulic conductivity the more effective the GCL will be at retaining seepage inside of the landfill. Bentonite composed predominantly (>70%) of montmorillonite or other expansive clays, are preferred and most commonly used in GCLs. A general GCL construction would consist of two layers of geosynthetics stitched together enclosing a layer of natural or processed sodium bentonite. Typically, woven and/or non-woven textile geosynthetics are used, however polyethylene or geomembrane layers or geogrid geotextiles materials have also been incorporated into the design or in place of a textile layer to increase strength.

GCLs range application
GCLs are suitable for municipal (landfill), water conservancy, environmental protection, artificial lake and underground waterproofing and anti-seepage projects. GCLs can still be constructed at minus 20 °C; but It can't be constructed under rain and snow; it is not suitable for anti-seepage of strong acid and strong alkaline solution; since bentonite is inorganic material, its durability is better than organic waterproof material.

GCLs waterproof principle
The bentonite particles swell with water to form a uniform colloidal system. Under the restriction of two layers of geotextiles, the bentonite is changed from disorder to ordered expansion. The result of continuous water absorption expansion is to make the bentonite layer itself dense, thus having Waterproof. The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into sodium and calcium based on chemical composition. Bentonite has the property of swelling with water. When calcium-based bentonite expands, its expansion is only about 3 times its own volume, while sodium-based bentonite absorbs five times its own weight when it meets water, and expands to 15-17 times or more. The sodium bentonite is locked in the middle of two layers of geosynthetic materials to protect and strengthen the GCL to have a certain overall shear strength.

GCLs features
1. Compactness: sodium bentonite in a state of formation of high density diaphragm during water pressure in thickness of about 3mm , its permeability equivalent to 100 times of 30cm thickness clay liner, with a strong self-protection water performance. 2. With a permanent waterproof performance: because of natural sodium bentonite -based inorganic material , even after a very long time or changes in the surrounding environment , aging or corrosion does not occur. 3. Simple construction and short construction period: comparing to other waterproof materials, GCL is relatively simple and does not require heating and paste, just bentonite powder and nails , washers, etc. After construction does not require special inspection , if found defective water is also easy to repair. 4. Subject to temperature effects: In cold weather conditions will not be brittle . 5. Waterproofing materials and objects Integration: sodium bentonite with a capacity of 20-28 times the expansion , even concrete structures vibrate and subsidence , GCL bentonite within less than 2mm can repair cracks in the concrete surface. 6. Environment friendly: Bentonite is a natural inorganic material , harmless non-toxic, no particular effect on the environment , with good environmental performance.

GCLs application

1. Municipal engineering, subway, underground construction of buildings and anti-seepage of roof storage tanks.

2. Environmental sanitation, domestic waste landfill, sewage treatment plant, industrial waste.

3. Water conservancy, anti-seepage, plugging and reinforcement of river and lake reservoir dams.

4. The ponds of the artificial lake golf course in the garden are impervious.

5. Anti-seepage, anti-corrosion, anti-leakage and reinforcement of engineering in petrochemical, mining and agricultural fields.

GCLs Matters needing attention

1. The storage and transportation of bentonite composite waterproof mat (GCL) should be waterproof, moisture-proof and strong against sunlight. When storing, the ground should be padded by overhead method, and the bentonite composite waterproof pad (GCL) shipped to the site should be used up on the same day.

2. When carrying out the next process or adjacent construction, the bentonite composite waterproof pad (GCL) of the completed process should be properly protected and there should be no human damage.

3, should try to avoid wearing spike shoes, high heels on the bentonite composite waterproof pad (GCL) stepping on;

Machinery such as vehicles shall not crush bentonite composite waterproof mat (GCL).

4. In the construction of GM/GCL composite liner, the completed GCL should complete the construction of HDPE film or lay a 300mm thick clay protective layer on the same day. The construction of HDPE film or clay protective layer cannot be completed on the same day, and the GCL should be covered. In order to prevent rain and snow, GCL will be hydrated first and strong sunlight will be exposed to GCL
