For diaphragm wall equipment, Malcolm Drilling owns and operates the largest fleet of state-of-the-art mechanical/hydraulic grabs and diaphragm wall cutters in North America. Their equipment can excavate panels to depths exceeding 300 feet. Their diaphragm wall support equipment includes electrical distribution stations, silos, colloidal mixers, slurry tanks, high-capacity slurry pumps, desander/desilter, and centrifuges, all required to mix, store, circulate, and recycle the fluid required to stabilize the excavation panel. One cutter unit is specially built for very low headroom conditions.
