Fildrain - Fin Drains
Fildrain findrain has a unique drainage core that collects and channels liquids and gases to a carrier pipe for transportation to a suitable discharge point.
Fildrain - Fin Drains
Fildrain findrain drainage geocomposite is a cost effective alternative to traditional stone drainage. It collects and channels liquids and gases to a carrier pipe for transportation to a suitable discharge point. Fildrain fin drain has many applications in surface and sub-surface drainage.
- French drains
- Groundwater drains
- Cut-off drains
- Combined surface and sub-surface drainage
- Capillary Break
- Gas venting and collection
- Drainage to concrete channels to DFT HCD figure F21
- Edge of carriageway drainage system to DFT figure F18
- Cost effective
- High water flows compared to traditional drainage stone
- Space saving, narrow trench requirement
- Re-use of site won excavated material
- Reduction or elimination of drainage stone
- Speed up consolidation
- Rapid installation
- Allows water flow in all directions
- Reduction in haulage requirements
Geocomposite drainage is suitable for dealing with ground water and ground water plus surface water. For situations with combined surface water and ground water, e.g. French Drains, the surface water must pass through a layer of filter stone before reaching the geocomposite drain. This filer stone, typically 300mm deep, will trap the silt and detritus and can be periodically excavated and replaced.
ABG Fildrain Fin Drain geocomposite filters surface water or ground water channeling to a discharge pipe, providing an ideal alternative for ‘traditional’ stone and constructions in the formation of surface and subsurface drainage systems saving time and money on construction projects.

Fildrain 12SW + 25SW
In many instances traditional detail can be replaced with a Fildrain "Fin Drain" gecomposite strip. This allows the excavated material to be simply backfilled into the trench and requires no import of clean aggregate. At the end of each run, a Fildrain fitting is used to connect to the outfall pipe. A low cost system with low embedded carbon which is suitable for mechanical installation.
Fildrain 7DWP or 7DWF
When high longitudinal flow capacity is required, Fildrain fin drain geocomposite is combined with a perforated pipe, pipe diameter is typically 100mm but this could be over 1000mm. Another low cost, low carbon solution.
Incorporating a pipe with sealed invert is ideal when large volumes of surface water are to be collected. Can be supplied with de-stressed and slotted 6m twin wall pipe.
Traditional French Drain Construction
Consists of an excavated trench, infilled with free-draining aggregate. This type of construction may require off-site material import and the removal of excavated materials. Trench width is typically 300mm to 500mm, a high cost option with a large carbon footprint.
