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

- Waterproof, anti-corrosion, anti-leakage, reinforcement, etc. in petrochemical, mining, agricultural and other fields.
Geosynthetics Clay Liner (GCL) Rol en ingeniería – 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 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 ambient temperature. It can also be constructed below 0°C. You only need to spread the Geosynthetics Clay Liner (GCL) on the ground during construction, and fix it with nails and washers during vertical or inclined construction, and overlap it as needed.
- Easy to repair; even after the waterproof (seepage) construction is completed, if the waterproof layer is accidentally damaged, as long as the damaged part is simply repaired, the perfect waterproof performance can be restored.
- The performance-price ratio is relatively high and the application is very wide.
- The product has a width of up to 6 meters, which meets international geotextile (membrane) specifications, which greatly improves construction efficiency.

MANUFACTURING QUALITY ASSURANCE
GEOFANTEX has an on-site Manufacturing Quality Assurance Laboratory at the factory. GEOFANTEX maintains a high level of quality and up-to-the-minute results on finished products through a fully equipped, well-staffed, dedicated laboratory existing in each of the manufacturing facilities. Each facility follows the same guidelines for evaluating the quality of GEOFANTEX products and is capable of adapting to market-driven requirements.
A. Objective
The objective of the GEOFANTEX Quality Assurance program is to define the implementation of basic manufacturing quality assurance (MQA) procedures necessary to ensure the consistent production of quality products supplied to the geosynthetic market. Note that at this time, these procedures are limited to polypropylene staple fiber nonwoven geotextile.
B. Scope
In order to achieve GEOFANTEX’s stated purpose, a rigorous set of minimum standards and an effective test program to assure compliance have been established. These procedures and requirements are frequently reviewed and adjusted to assure compliance with current market demands and/or predetermined project specifications. These procedures assure that raw materials and process parameters are controlled to provide products complying with GEOFANTEX’s pre-defined minimum characteristics.
PRODUCT IDENTIFICATION AND DOCUMENTATION
A. Roll Numbering
Each roll of geotextile 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 standards 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 needle punched nonwoven geotextile product to include all relevant quality assurance information about the material(s).
