TerraDrain® Sheet Drains

TerraDrain® sheet drains offer a cost-effective alternative to conventional aggregate drainage systems. They reduce hydrostatic pressure and transport ground water away from below grade structures.

Hanes Geo offers three series of sheet drain products, 50 Series (moderate strength/flow) and 101 Series (moderate strength/high flow), 100 Series (high strength, high flow). The 50 and 100 Series are available with multiple drainage geotextile options, including AASHTO M288 compliant products.

TerraDrain® sheet drains are constructed using a polymeric core with a nonwoven filter fabric bonded to one side. The filter fabric is designed to prevent soil intrusion while allowing water to freely enter the drain core, which provides an uninterrupted path for water to flow to designated drainage exits.
