Retaining Wall Subdrainage Systems

Retaining Wall Subdrainage Systems

Drainage geocomposites are commonly utilized in subdrainage system applications for retaining walls and undergroundbuildings.

The subdrainage system designed on the face of a retaining wall have to be capable of draining water within the saturated soil to prevent hydrostatic loads that could destabilize the retaining wall system and to prevent humidity to emerge from the backsoil.

The subdrainage system traditionally consists of a vertical layer of gravel encapsulated by a non-woven geotextile along the wall. Construction procedures for this type of systems are usually complicated, using wooden forms in order to retain the gravel while placing and compacting the backfill soil material.

All of this can be replaced with the utilization of a drainage geocomposite, which can be installed easily by pasting it on the face of the wall, thus providing an economical, easy and rapid solution for the construction of subdrainage systems for retaining walls and underground buildings.
