Capability ; 100mm diameter piles
Capacity – 50kN max
Micro piles are constructed by driving sections of thin-walled casings into the ground (typically 2m long). A piling mole is installed into the lead casing which drives it into the ground.
Once a section of casing has been driven into the ground, additional casings are welded on to drive the pile deeper. This process is repeated until the pile has reached the required depth.
Upon reaching the required depth, the piling mole is withdrawn from the casings. The hollow casing left in the ground is then filled with concrete and reinforcement.
To complete the pile, a reinforcement bar is plunged into the wet concrete to the required depth.
As a micro pile does not require a conventional piling rig for installation. It is possible to install these piles in very restricted locations.
