With the correct micropile drilling rigs, it’s probable to allow with the installation of micropiles in practically any locale, like areas which have restricted accessibility or merely a small degree of headroom, GeoCraft can install piles with as minor as twelve’ of overhead clearance!

Pile cushions, because the name implies, are largely protection to the pile particularly, precast concrete piles. Pile cushions guard the ends of the pile from spalling harm that may happen if the hammer blow impacts the pile. The cushion also supplies attenuation in the blow all through driving, lowering tensile forces performing over the pre-stressed pile as it truly is driven. Pile cushions are offered in several thicknesses and sizes to accommodate the pile as well as travel cap, and so are determined by the driving situations as dictated by the dimensions in the hammer and also the soil. As Each and every venture is different, so would be the cushions distinctive to The actual task at hand.
