100mm Black Unperforated Land Drain Coil - 25m

This 25m coil of black 100mm unperforated land drain is a single wall, corrugated pipe manufactured from high-density polyethylene. It is designed for fast, straightforward installation and effective water flow in land drainage and attenuation applications.

Unlike perforated land drain, this unperforated coil has no holes for water to enter the pipe. It is used to distribute collected surface water to a suitable outfall, such as a watercourse, soakaway, French drain, attenuation crate system or water storage tank.

Features & benefits include:

• Manufactured from HDPE for a durable, lightweight drainage solution
• Unperforated solid wall design for distributing collected water
• Corrugated profile for added pipe strength
• Suitable for attenuation and surface water transfer applications
• Cost-effective option for a wide range of land drainage projects
• Non-kite marked
