Polypipe are established manufacturers of below ground drainage and stormwater management products used across domestic, commercial and civil engineering projects.
Their perforated land drainage pipe is commonly installed within French drains and equestrian arena drainage layouts. When wrapped in a suitable non woven geotextile membrane, it prevents silt and clay ingress which can otherwise block the pipe and reduce performance.
Twinwall drainage systems are used for deeper or trafficked installations such as driveways, roads and commercial yards. The structured outer wall provides strength, while the smooth bore maintains flow efficiency. Correct bedding and surround material are critical to prevent pipe deformation under load.
Inspection chambers and access fittings allow maintenance access and changes in direction within drainage runs. In attenuation and controlled discharge systems, Polypipe components are often integrated with soakaway crates or modular storage systems.
On clay soils with low permeability, simple soakaways may not be suitable. In these cases, attenuation systems with controlled outflow are required. Proper specification depends on ground conditions, loading class and discharge requirements.
Polypipe systems manage water effectively when installed correctly. Performance depends on correct falls, suitable backfill and appropriate geotextile separation to prevent migration of fines into the drainage layer.
