Product Detail
A sodium bentonite geosynthetic clay liner (GCL) is a manufactured hydraulic barrier used in various civil and environmental engineering applications. Here's a breakdown of what they are and their key features:
What they are:
Composition:
GCLs consist of a thin layer of sodium bentonite clay sandwiched between two geotextile layers (woven or non-woven).
The geotextiles are typically needle-punched or stitched together to hold the bentonite in place.
Function:
The sodium bentonite clay has a unique property: it expands significantly when hydrated, creating a very low permeability barrier. This effectively prevents the movement of liquids.
Features
Key Features and Benefits:
Low Permeability:
GCLs offer excellent hydraulic performance, often exceeding that of traditional compacted clay liners.
Self-Healing:
The swelling property of bentonite allows it to seal small punctures or cracks, providing a self-healing capability.
Ease of Installation:
Compared to compacted clay, GCLs are easier and faster to install, reducing construction time and costs.
Space Efficiency:
GCLs are much thinner than compacted clay liners, saving valuable space in applications like landfills.
Durability:
They are designed to withstand various environmental conditions and chemical exposures.
Common Applications:
Landfill Liners and Caps:
To prevent leachate from contaminating groundwater.
Ponds and Reservoirs:
To provide a waterproof barrier.
Canals and Irrigation Channels:
To prevent water loss.
Groundwater Barriers:
To control groundwater flow.
Road and Railway Construction:
To enhance soil stabilization.
In essence, sodium bentonite GCLs are a reliable and efficient solution for containment and hydraulic barrier applications.
