Product Details

Perforated land drainage is designed to collect surface water through small holes cut in the dwells of the coil. In agriculture, this assists drainage in fields and improves soil quality. In construction, it alleviates flooding and relieves static load on underground structures and retaining walls.

Perforated land drain is also useful in Sports Fields, Lawn & Garden drainage (in smaller diameters), and can also feature in French Drains to improve drainage.

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. Actual slot length of perforations can exceed the design value by up to 50%.

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.
