Helical piles and steel foundations are perfectly suited to waterlogged and marshland where the use of concrete is not viable due to the saturated ground conditions. The screw piles penetrate beyond the waterlogged soil – without excavation – to a depth where the soil strength is capable of generating sufficient bearing capacity.
Since excavation is not required, the process negates the difficult task of transporting the removed soil, or potentially contaminating 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.
Helical piles are just one of the many foundation solutions which ScrewFast Foundations design and supply for environmental projects, including:
- Bottom Driven Piles
- Overburden Drilling Systems
- Micro Piles
- CFA Piles
Examples of projects that ScrewFast has been involved with in the Environmental sector include:
- Flood Defences
- Retaining Walls
