Pile cushions are presented in numerous thicknesses and sizes to support the pile as well as the travel cap, and so are based on the driving circumstances as Micro pile foundation repair dictated by the scale from the hammer as well as soil. As Every single job is different, so tend to be the cushions distinctive to The actual project at hand.
