TerraDrain® Strip Drains

TerraDrain® prefabricated strip drains are constructed by fully wrapping a perforated, high flow capacity polymeric core with a nonwoven filter fabric. The filter fabric is bonded to the core and prevents soil intrusion into the flow channels while allowing water to freely enter the drain core from all sides. TerraDrain® strip drains offer a cost effective, performance-driven alternative to traditional perforated pipe and stone French drain systems.

Hanes Geo offers two series of strip drain products, 600 Series (moderate flow/strength) and 900 Series (high flow/strength). Both are available with multiple drainage geotextile options, including AASHTO M288 compliant products.

TerraDrain® strip drains are constructed by fully wrapping a perforated, high flow capacity polymeric core with a nonwoven filter fabric. The filter fabric is bonded to the core and prevents soil intrusion into the flow channels while allowing water to freely enter the drain core from all sides.

All TerraDrain® Strip products are available in 6”, 12”, 18”, and 24” widths
