Bentonite Clay Liners For Landfills Geosynthetics Clay Liners In Coal Ash Disposal Facilities


GCL is a new environmentally friendly composite waterproof impermeable material, it’s bentonite particles filled in woven and nonwoven geotextile between the upper layer of non-woven fibers through the bentonite particles, through a special process and equipment, with the acupuncture method of weaving on the link in the lower composite. Geosynthetic Clay Liner has the advantages of small size, light weight, good flexibility and seal easy for construction and suitable for uneven settlement. The GCL normally used in environment engineering or landfill emissions, underground reservoirs, underground infrastructure construction projects, sealing solution, segregation, anti-leakage, good effect, anti-destructive.

  1. A permanent waterproof performance, and excellent water seepage performance, impermeability hydrostatic pressure up to 1.0MPa above, permeability coefficient 5 *10-9cm / s. Because the Department of Natural sodium bentonite inorganic materials, even after a long time or the surrounding environment changes, aging or corrosion does not occur.
  2. Has all the characteristics of geotextile material, such as separation, reinforcement, protection, filtration, simple construction and unrestricted construction environment temperature below 0 0 C also be construction. Just when construction GCL waterproof blanket tile on the floor, when the elevation or slope construction, with nails and washers to secure it, as required, can overlap.
  3. Easy to repair; Even after water (seepage) end of construction, such as waterproof layer accident damage, as long as the site of the damage to be a simple fix, can ever regain perfect waterproof performance.
  4. Green: Bentonite is a natural inorganic material, harmless, non-toxic,no particular impact on the environment, with good environmental performance.
  5. Simple construction period is short: and other waterproof materials, the construction is relatively simple, does not require heating and paste. Product width up to 6 meters, with international geotextile (film) to match the size, greatly improving the efficiency of construction.
  6. Integrated waterproof materials and objects: When sodium bentonite water, with 20-28 times the capacity expansion, even if the concrete structure vibration and settlement, bentonite GCL can repair cracks in the concrete surface less than 2mm.


  • 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.
  • 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.
  • 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.
  • Subject to temperature effects: In cold weather conditions will not be brittle .
  • 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.
  • Environment friendly: Bentonite is a natural inorganic material , harmless non-toxic, no particular effect on the environment , with good environmental performance.
