Underpinning Preloading


Underpinning is a method used to strengthen existing foundations, by the installation of micropiles around a existing foundation and construction of a combined foundation. Underpinning is carried out using the bored and driven micropiling systems.


Preloading of piles, an additional procedure done in conjunction with underpinning, involves a patented technique of pumping a fluid into the preloading cell placed on top of the pile. This causes a reduction in the settlement of the pile.This helps to create a more stable foundation for the structure.
