Geosynthetic Clay Liner (GCL) is a kind of gree material and good to environmential protection anti-leakage product.
Geosynthetic clay liners (GCLs) are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).when hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay.
It is used to prevent water leakages in areas of artificial lakes, waste disposal fields, underground garage, top building gardens, reservoirs, oil warehouses, and chemicals accumulating fields.

Features:

1. Improved leakage performance
2. Permanent waterproof performance
3. Simple construction and short time limit for a project.
4. Not influenced by air temperature.
5. A kind of green material and good to environmental protection.
6. More versatile than compacted clay
7. Increased airspace and liner efficiency

Application

In infrastructure projects, uneven soil settlement, erosion, and water permeation often pose potential threats to structural stability. Our geosynthetic materials provide effective solutions to these challenges.
Geomembranes can effectively block liquid permeation and are widely used in waterproofing applications such as reservoirs, canals, and landfill liners.
Geotextiles, with their filtration and separation functions, protect soil layers and ensure the stability of road bases and foundations.
Geogrids enhance soil load-bearing capacity and provide crucial support for roads, slopes, and bridges. and other structures.
We offer a comprehensive one-stop geotechnical solution, including professional support throughout material selection, design, and construction. This empowers our clients to address complex geotechnical challenges and ensures the long-term stability and efficient operation of their projects.
