This 50m coil of black 160mm unperforated land drain is a single wall, corrugated pipe manufactured from high-density polyethylene intended to allow fast and easy installation and excellent water flow.

Unperforated land drain is designed for distributing collected surface water as, unlike perforated coils, they have no holes for water to drain in to. This is primarily for attenuation where water is stored and sent to a watercourse (such as a stream or river), a soakaway/french drain, attenuation crates or a water storage tank.

Customer Advice: When installing land drain, the trench you dig needs to be wider than the diameter of the pipe and MUST be at least 450mm deep. This is important if you are planning on aerating your lawn - the pipe must be deep enough so it's not damaged by spiking or other maintenance - Check out our Basic Guide to Land Drain for more advice and information.
