Pile cushions, given that the title indicates, are primarily safety for the pile specially, precast concrete piles. Pile cushions safeguard the finishes in the pile from spalling destruction that might take place once the hammer blow impacts the pile. The cushion also presents attenuation in the blow during driving, lessening tensile forces performing within the pre-pressured pile as it's driven. Pile cushions are presented in numerous thicknesses and dimensions to support the pile and also the push cap, and are determined by the driving conditions as dictated by the size in the hammer as well as the soil.
