This 25m coil of black 100mm perforated land drain is a single wall, corrugated pipe manufactured from high-density polyethylene intended to allow fast and easy installation and excellent water flow.
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.
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.
