GeoFanDrain® BC R7035
- 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.
- 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.
GeoFanDrain® BC R7035:
- Dam & Saline Land Drainage
- Retaining Walls & Tunnels Drainage
- Sports Fields & Garden Drainage
- Road & Railway Subgrade Drainage
