Instant Foundations screw piles can be used effectively in underpinning failed buildings. A screw piling rig can work from the inside the building with limited head height and use segmented piles as required.
There is a range of sizes of excavator-based screw piling rigs for underpinning applications. Underpinning piling rigs with weights of between three and five tonnes can be used with ease to achieve the required pile load capacities in domestic or commercial construction.
For larger commercial projects were the loads are in excess of 30 tonnes, excavator piling rigs will install screw piles to suit the underpinning requirements. The equipment can also excavate the pile caps and footing beams.
