Drilled concrete pile walls are created when the individual drilled holes intersect and are called secant or caisson walls. These walls are more expensive than most shoring solutions but offer minimal movement.

Bermingham has built these walls utilising 880 mm to 1500 mm diameter tooling and as deep as 42 metres (136 ft). We recently completed a condominium project that boasted the first eight-storey underground parking garage in downtown Toronto.

Bermingham utilises its fleet of Euro-style drill rigs for this work.
