The cushion also offers attenuation of the blow for the duration of driving, minimizing tensile forces acting on the pre-pressured pile as it truly is pushed. Pile cushions are furnished in several thicknesses and measurements to accommodate the pile as well as generate cap, and are based on the driving problems as dictated by the dimensions from the hammer and the soil. As Just about every undertaking is different, so tend to be the cushions distinctive to The actual venture at hand.
