Pile cushions secure the finishes with the pile from spalling harm that would come about in the event the hammer blow impacts the pile. The cushion also gives attenuation of the blow through driving, decreasing tensile forces performing around the pre-stressed pile as it truly is pushed. Pile cushions are supplied in many thicknesses and sizes to support the pile as well as push cap, and are determined by the driving disorders as dictated by the dimensions with the hammer and the soil.
