Lagging Wall Drainage

Lagging Wall Drainage

Application Description:

Lagging walls systems are routinely used for supporting excavation in urban environments where property lines and roads prohibit sloped or benched construction. They are used to retain soil until permanent walls are constructed. Providing suitable drainage, especially in high water table situations, present a unique challenge to the design professional due to the restricted area between the excavation and structural wall.

J•DRAIN drainage composites are engineered to be installed between the lagging and structural wall to reduce hydrostatic pressure and minimize leaks while efficiently channeling the water away. The three dimensional core creates a high compressive strength and high flow capacity drainage channel and the fused filter fabric prevents soil intrusion into the flow channel. It also provides a suitable substrate for the application of shotcrete or structural concrete. Inefficient drainage of the backfill may result in premature failure.
