Sheet Drain Geocomposites

Prefabricated Sheet Drain

Geocomposite prefabricated sheet drains are composed of a dimpled polymeric core with a woven or nonwoven geotextile bonded to one or both sides. The geotextile allows water to pass through while retaining backfill materials.

Some products use a solid core that allows water collection from one side and provides a continuous flow path to designated drainage exits, while others use a perforated core that allows water collection from both sides.

Available in 4', 6', or 8' Widths.

These products provide an economical solution for subsurface drainage applications requiring high strength, high flow capacity, and/or require a geotextile meeting an AASHTO M288 requirement.
