Product Details
Geosynthetics Clay Liner Supplier(GCL) – Geofantex
The Geosynthetics Clay Liner is a kind of geosynthetic material specially used for anti-seepage of artificial lakes, waterscapes, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. It is made of highly expansive sodium-based bentonite is filled between the special composite woven geotextile and non-woven geotextile. The bentonite impermeable pad made by needle punching can form many small fiber spaces. The bentonite particles cannot flow in one direction, and they stay in the pad when it meets water. A uniform and high-density colloidal waterproof layer is formed to effectively prevent water leakage.
Could be manufactured according to your inquiry, MINIMUM ORDER QUANTITY: 20’ft Container

- Waterproof ponds in gardens, artificial lakes, golf courses, etc.
- Waterproof, anti-corrosion, anti-leakage, reinforcement, etc. in petrochemical, mining, agricultural and other fields.
Geosynthetics Clay Liner (GCL) Role in engineering – Geofantex
- It has excellent waterproof and anti-seepage performance, the anti-seepage hydrostatic pressure can reach 1.0MPa or more, and the permeability coefficient is 5×10-9cm/s. Bentonite is a natural inorganic material, which will not cause an aging reaction and has good durability; Any adverse effects on the environment are environmentally friendly materials
- It has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and is not restricted by the construction environment temperature. It can also be constructed below 0°C. Only need to spread the Geosynthetics Clay Liner factory (GCL) on the ground during construction, fix it with nails and washers during vertical or inclined construction, and lap it as required.
- Easy to repair; even after the completion of the waterproof (seepage) construction, if the waterproof layer is accidentally damaged, as long as the damaged part is simply repaired, the perfect waterproof performance can be regained.
- The performance-to-price ratio is relatively high, and the application is very wide.
- The product has a width of up to 6 meters, which matches the international geotextile (membrane) specifications, which greatly improves the construction efficiency.

These procedures assure that raw materials and process parameters are controlled to provide products complying with GEOFANTEX’s pre-defined minimum characteristics.
PET Geogrid PRODUCT IDENTIFICATION AND DOCUMENTATION
A. Roll Numbering
Each roll of Geosynthetics Clay Liner (GCL) is assigned a unique roll number. The Quality Assurance Laboratory maintains records documenting the raw materials and resulting product quality information.
B. Approval Procedure
Results for each tested roll of the product are checked against both GEOFANTEX China standard and customer specifications for compliance. The Quality Assurance Laboratory approves those materials that meet these requirements for shipment.
C. Non-Conformance
Material that does not meet GEOFANTEX minimum standards is given a roll number but is rejected and not placed into inventory. The material is identified as scrap and will not be utilized. Material that meets GEOFANTEX minimum standards but does not meet a stricter customer specification is not allocated to that customer but is placed into inventory as GEOFANTEX standard material.
D. Documentation
Individual Quality Assurance Certificates are generated and supplied for each roll of Geosynthetics Clay Liner (GCL) product to include all relevant quality assurance information about the material(s).

What is Geosynthetics Clay Liner (GCL) – Geofantex
Geosynthetics Clay Liner (GCL) is an impermeable liner between GCL and polymer material-geomembrane. Mainly used in environmental engineering waste landfills, underground reservoirs, underground infrastructure construction and other projects to solve the problems of sealing, isolation, and leakage prevention, with good effect and strong resistance to destruction.
Bentonite Geosynthetics Clay Liner (GCL) can be divided into needle-punched sodium-based Bentonite Geosynthetics Clay Liner, needle-punched film-coated Bentonite Geosynthetics Clay Liner, and adhesive-processed Bentonite Geosynthetics Clay Liner. The needle-punched membrane-coated Bentonite Geosynthetics Clay Liner is a layer of high-density polyethylene geomembrane compounded on the outer surface of the non-woven geotextile of the needle-punched Bentonite Geosynthetics Clay Liner. Adhesive method sodium-based Bentonite Geosynthetics Clay Liner is a kind of sodium-based bentonite produced by bonding bentonite particles to a high-density polyethylene board with an adhesive
What is the function of geosynthetics clay liner?
Function. The engineering function of a GCL is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases. As such, they are used as replacements for either compacted clay liners or geomembranes, or they are used in a composite manner to augment the more traditional liner materials.
What is the working and advantage of geosynthetic clay liners?
GCLs provide an excellent alternative to conventional Compacted Clay Liners by replacing a thick section of compacted clay with a thin layer of pure sodium bentonite. Benefits include easy installation, better hydraulic performance and resistance to varying weather conditions.
What are difference between geosynthetic clay liner and compacted clay liner?
Long-term performance: GCLs eliminate the problems of differential settlement and are less impacted by desiccation-rewetting cycles owing to the high plasticity and self-healing capabilities of sodium bentonite. The traditional compacted clay liners succumb to these conditions and crack up.
