Pile cushions, as the title implies, are principally defense for that pile precisely, precast concrete piles. Pile cushions secure the finishes with the pile from spalling damage that will arise if the hammer blow impacts the pile. The cushion also supplies attenuation in the blow for the duration of driving, minimizing tensile forces acting around the pre-pressured pile as it can be driven. Pile cushions are presented in different thicknesses and sizes to support the pile along with the generate cap, and are based on the driving circumstances as dictated by the scale Micro pile contractors on the hammer along with the soil.
