Helical piles are suited to waterlogged and marshland where the use of concrete is not viable due to saturated ground conditions. The screw piles penetrate beyond the waterlogged soil to a depth where the soil strength is capable of generating sufficient bearing capacity.
The other benefits which can be realised include avoiding the difficult process of soil excavation, and potential contamination of the surrounding environment leading to a negative environmental legacy. A small excavator can be used to install the screw piles, which allows remote locations to be reached comfortably. Urgent projects can be completed quickly and modular bridges are possible, as the foundations are ready for immediate loading once installed.
Examples of projects that ScrewFast has been involved with in the Environmental sector include:
- Flood Defences
- Retaining Walls
