Product Details

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.

Installation 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.

Compatibility

This pipe is not suitable for use as a dispersal drain for septic tanks.

Manufacturer's Advice

Long term storage outside can result in damage to the product by UV degradation. Storage longer than 12 months is therefore not recommended.
