Features and Benefits
In some fine sand and coarse silt soils,a geotextile sleeve or ‘filter sock’ may be used to prevent fine granular filter material entering the slotted pipe. The filter sock stabilises the soil by bridging the pipe corrugations and supporting the soil immediately around the pipe. This restricts the sediment from entering the drainline.
Filter sock material is available in ‘POLYESTER’ fabric in two grades, standard and RTA grade for general and road applications. The RTA grade is a heavier fabric and conforms to NSW Roads and Maritime (formerly RTA) specifications. A special chemical resistant ‘POLYPROPYLENE’ filter sock is also available for mining and industrial applications.
A comprehensive range of simple push together fittings which lock to the corrugations of the Draincoil pipe completes the Draincoil system.
Fittings include couplings, caps, tees, 45° Y junctions, crosses and adaptors to connect to PVC stormwater and DWV pipes
Custom fabricated fittings are also available.
Ease of Installation – Draincoil is available in easy-to-handle coils. Because of its light weight, it can be transported over difficult terrain and across wet areas during installation. The long lengths facilitate high speed installation using a backhoe, chain digger or direct ploughing into the soil.
Flexibility – Draincoil pipes can be installed continuously around curves and corners of 300mm radius without the need for additional fittings. Any soil movement is accommodated by the flexibility of Draincoil.
Effective Drainage – Drainage water enters Draincoil through the uniform slot patterns in the protected valleys of the corrugations. An even entry of water along the pipe length provides efficient and effective drainage.
Robustness – The corrugated structure provides excellent strength to resist external loads from either soil backfill or vehicles, once installed.
Effective Drainage – Drainage water enters Draincoil through the uniform slot patterns in the protected valleys of the corrugations. An even entry of water along the pipe length provides efficient and effective drainage. Uniformly arrayed small holes and high hole density give optimum drainage,creating a uniform hydraulic gradient through the filter medium, and slots with an aspect ration minimum of 4:1 enable arch formation of small grains without clogging.
Corrosion Resistance – Draincoil is unaffected by aggressive soil conditions. The chemical resistance of the polyethylene and PVC materials used in its manufacture is well established and documented.
