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 (specific data is available). 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 adjacent to the drain. 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 which is suitable for manual or mechanical installation.
