Fildrain drainage geocomposites are a cost effective alternative to traditional stone drainage for linear trackside cess drains. The geocomposite collects and channels liquids and gases to a carrier pipe for transportation to a suitable discharge point.
Fildrain has a unique drainage core that collects and channels water from the trackside to a carrier pipe for transportation to a suitable discharge point.
Fildrain fin drains provide a very high flow capacity, many times that of traditional crushed stone. This is due to the unique open structure created by the dimpled construction which allows un-hindered water flow.
ABG Fildrain fin drain geocomposites, for trackside edge channel drains, channel surface water to a discharge drainage pipe, providing an ideal alternative to the construction of ‘traditional’ narrow stone filter drains, saving time and money on railway construction projects.
ABG Fildrain Type 6 edge drain provides vertical drainage on both sides, whilst acting as a barrier to protect the sub-base from inundation from the verge. Fildrain Type 6 fin drain system is a double cuspated drainage geocomposite, fully wrapped with a filter geotextile and an integral pipe sleeve. The Fildrain geocomposite is laid alongside the trench, threaded with perforated pipe and dropped into a narrow trench before backfilling by pushing and compacting the excavated soil back into the trench. The surface is then covered with soil or a shallow apron of stone.
The ABG Fildrain Type 7 fin drain is a BBA certified findrain system that incorporates a pipe with a sealed invert, ideal for when large volumes of surface water are to be collected.
The ABG Fildrain Type 5 is a BBA certified fin drain system. The Fildrain Type 5 Fin Drain geocomposite strip 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. The Type 5 fin drain system is a low cost option, with low embedded carbon suitable for manual or mechanical installation.
