New embankment construction project using Fildrain drainage layers
Drainage systems for earthworks engineering projects including:
Recycled Fill
One of the major costs in construction is the import of a suitable fill material. Fildrain provides high tensile strength and high in-plane flow capacity, and ensure excellent reinforcement and separation. Compared to crushed stone these geocomposite layers are lighter, easier to transport and help conserve finite resources. The high drainage capacity can allow low grade recycled materials to be used as backfill rather than being disposed of off-site whilst speeding up consolidation.
Embankments
Fildrain 7DD and 7DHD geocomposite drainage layers are the most advanced system for relieving pore pressure in the construction of new embankments. This proven method of construction is certified for the starter layer and subsequent layers through the height of the embankment to aid consolidation without expensive aggregate.
Embankment fill is placed with the optimum moisture content for compaction, which means the compacted fill is too wet to support long term loads without settlement. Fildrain is faster to install than crushed stone, and is impermeable in the vertical plane. This means earthworks are protected from the ingress of rainfall, and full consolidation can be achieved in 25% of the time normally expected.
Linear Assets
Findrains are widely used in Highway and Rail construction.
