The Land Drain perforated drainage coil pipe (10cm) by Polypipe (understood to be) is designed for effective tree planting and French drainage systems. Made from flexible plastic material with a matt finish, this pipe is suitable for use in both storm water management and underground drainage applications. With a length of greater than 50m (I originally bought 100m in in the end only used circa 40m), this product is ideal for efficiently draining soil and water in a variety of landscaping and agricultural projects. Collection from South Norwood, London, SE25
