Micro and Mini Piles
Micro Piles are a form of pile that are drilled into the ground, with a drill head attched to the front end of the pile. As the pile is drilled into the ground, it injects grout into the surrounding soil to make the foundation as strong and supportive as possible. They are usually made of high quality galvanised steel, typically in diameters of 60 to 200mm.
Mini piles are a form of Micro piles but are often have a smaller diameter than usual piles, they are used to support lighter structures.
Micro screw piling has considerable benefits under difficult site conditions such as these:
- Groundborne vibration must be avoided.
- Physical site constraints apply (e.g. low headroom).
- Requirement to operate in temperatures that are unsuitable for concrete piling.
- Ground conditions are unsuitable for other foundations.
- Excavation or removal of spoil is problematic.
- Conventional piles would be too heavy (a mini pile is a lightweight pile).
- Access is restricted for conventional piling equipment.
- The structure may be subject to significant overturning moments.
- Environmental constraints apply (especially noise and fumes).
Tension loads must be accommodated.
