GeoFanDrain® BC (plastic blind drain, also known as a French drain, rubble drain, blind ditch, or under drain), is a subsurface drainage system composed of a thermoplastic resin core and filtering cloth. The core is formed by extruding and welding plastic strips into a three-dimensional network structure, available in various shapes such as rectangular or round with holes or hollow centers. Compared to traditional blind ditches, it offers superior drainage, pressure resistance, light weight, and flexibility, reducing labor intensity and improving efficiency. It is widely used in highway subgrades, retaining walls, landfills, roof gardens, foundations, and underground irrigation.

Main Function of GeoFanDrain^® BC

Quickly directs groundwater or rainwater away from structures to prevent accumulation.

Reduces water pressure buildup behind retaining walls, tunnels, and foundations, minimizing structural stress.

Prevents fine soil from entering and clogging the drainage core, ensuring long-term performance.

The internal springActs as a cushioning layer to prevent mechanical damage from backfill or soil movement. steel skeleton enables the pipe to withstand heavy loads and deformation in buried conditions.

Controls subsurface water to prevent erosion, sliding, or settlement in embankments and engineered fills.
