Burst a variety of pipe types

Burst and replace water, sewer and other pipes with the Grundoburst static pipe bursting system from TT Technologies. Pulled by a hydraulic bursting unit, the cutter head’s special cutting wheels split the host pipe, while an attached expander spreads and displaces the split pipe into the surrounding soil while simultaneously pulling in the new pipe. The Grundoburst is able to burst ductile iron, steel and fracturable pipes as well. Patented quick-lock bursting rods are linked together instead of being threaded, which the company says saves time, prevents twisting and extends the life of the cutter head. Six models are available for bursting 2- through 54-inch pipes and larger.
