Product
Laminated GCL
Product providing dual-function containment with factory-laminated HDPE/LDPE film on GCL; creates a composite barrier in a single layer for hazardous waste and deep mining ponds.
Product Summary
GCL and geomembrane combined in a single layer
Laminated GCL combining the self-healing capacity of bentonite with the low permeability of the geomembrane film in a single product; limits field hydration risk and provides an additional barrier against gas and vapor diffusion. Since the top film is weldable, it works integrated with upper layer covers.
Structure
GCL + HDPE/LDPE Laminated Composite
Standard
ASTM D5887 / GRI-GCL3
Thickness
6 – 12 mm (4500 – 6500 g/m²)
Width
40 – 5.00 m
01 / 02
Technical Approach
Laminated GCL technical specifications highlighting the product
Achieving both a hydraulic barrier and a gas/vapor barrier in a single layer reduces the probability of error and shortens testing time compared to separately laid geomembrane and GCL systems.
Protection against early hydration with the top laminated film
Additional barrier against gas and vapor diffusion
Weldable HDPE/LDPE top surface
Protection against early hydration
The top laminated film prevents bentonite from hydrating prematurely under field conditions.
Product Structure
A structure meeting engineering requirements in a single product
It consists of a factory-laminated HDPE/LDPE film on the top surface, sodium bentonite in the middle layer, and a carrier geotextile on the bottom. While the top film undertakes the containment and gas barrier function, the bentonite self-heals through hydration.
