Robit has launched a cost-efficient integrated ring for large sacrificial casing, 508–1 524 mm / 20”–60”.
DTH SR products are economical and cost-effective in homogenous ground conditions where number and size of boulders are limited. One pilot design can be used to install both regular round piles and interlocked Pipe-Pile-Wall piles – just ring bits require different outside diameters. Robit® Solitary Ring Casing Systems are available for all common Down the Hole hammer designs and can be used in all applications where casing is left in the ground.
