The Grundoburst static pipe bursting system from TT Technologies can pull in a variety of replacement pipe, including PVC, DIP, ABS, cast iron, fusion welded HDPE and VCP jacking pipe. It uses a bladed cutter head to make bursting ductile iron and steel pipe possible. Pulled by a hydraulic bursting unit, the cutter head’s cutting wheels split the host pipe. An attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe. QuickLock bursting rods are linked together, not threaded, saving time, preventing twisting and extending the life of the cutter head. Six models are available for bursting 2- through 54-inch pipes.
