Geomembranes are commonly utilized in tunnels and canals applications to line and protect these kinds of structures.
Over time, concrete lined canals may crack, resulting in a significant loss of water. Geomembranes are used extensively in these applications due to their proven performance as effective and economical liners, providing many benefits such as durability in exposed conditions, resistance to a broad range of chemical substances, and rapid installation.
The demanding requirements of today’s tunnel designs include full encapsulation of tunnels with impervious, flexible and chemically inert geomembranes to ensure the tunnel remains dry at all times thereby allowing for continued construction activities and an extended useful life.
The most widely used configuration, concrete-geomembrane-concrete is employed for almost any type of tunnel construction. During construction, the outer layer of concrete holds the tunnel open until the waterproofing geomembrane can be installed. The inner layer of concrete, which acts as the main structure of the tunnel is then placed over the geomembrane.
Geomembranes assure waterproofing of the system even with slight differential settlements or seismic activity due to their flexibility, thus protecting the integrity and functionality of these kinds of structures.
