The prevention of ingress of groundwater into man made structures is the key to their longevity.

The use of round clay pipes to remove unwanted water from developed areas dates back to ancient times, however only in the 20th century were engineers provided with an alternative to the clay pipe. Modern drainage pipes are now manufactured from various polymers to provide strength, durability, flexibility light weight to allow simple installation.
Greenflo® is a 100mm diameter single wall Class 400 pipe, manufactured in from recycled High Density Polyethylene (HDPE). Greenflo® is a flexible yet durable pipe which can be supplied as plain pipe with no slots or a subsoil drainage pipe with slots. A further option incorporates a knitted filtration sock over the full length of the pipe
Designed for medium load conditions the single wall pipe is suitable for non highway drainage applications. The single wall ensures a high degree of flexibility which allows Greenflo® to be supplied in large coils which helps reduce installation costs.

The use of traditional French drains incorporating perforated drainage pipes in roads, sports fields and general landscaping is commonplace and is proven technology. The high flow capacity of the Greenflo® allows the rapid removal of water from the base of the French drain
