Fig. 1

The use of a GCL to prevent any hazardous liquids or constituents resulting from vehicle, from entering the sensitive location, mainly in infrastructure applications, such as roads, is shown in Fig. 1. Since the confining stress is typically low (less than in 50 kN/m²) in these applications the GCL performance is dominated by the hydraulic head, which is in most cases liquids other than water. The stability of the GCL is influenced by the slope angle , the normal load gradients, and the interface friction angle , with adjacent layers. Freeze/thaw effects as well as dry/wet cycles in these applications are location dependent and are of less of a concern with a thickness of cover material over the GCL greater than 1m (3 feet).

Bentofix® GCLs with a nonwoven on both sides typically allows steeper designs than with woven components, due to an increase of the interface friction angle.

Secondary Containment—The use of a GCL to provide secondary containment for a tank is shown on Fig. 1. The function of the GCL in this application is to prevent any hazardous liquids or constituents resulting storage silos or similar containments from entering the sensitive location. Since the confining stress is typically low (less than in 50 kN/m²) in these applications the GCL performance is dominated by the hydraulic head, which is in most cases liquids other than water. The stability of the GCL is influenced by the slope, , the normal load gradients, and the interface friction, , with adjacent layers. Freeze/thaw effects as well as dry/wet cycles in these applications are location dependent and are of a design concern.
