Utility equipment: Burst and replace water, sewer, gas and other pipes with the Grundoburst static pipe bursting system from TT Technologies. The Grundoburst can pull in a variety of replacement pipe including PVC, DIP, ABS, cast iron, fusion welded HDPE and VCP jacking pipe.
The Grundoburst static pipe bursting system utilizes a specially designed bladed cutter head to make bursting ductile iron and steel pipe possible. Pulled by a hydraulic bursting unit, the cutter head’s special 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.
Patented QuickLock bursting rods are linked together not threaded. This saves time, prevents twisting and extends the life of the cutter head over threaded bursting rods.
Six Grundoburst models are available for bursting 2-inch through 54-inch pipes and larger.
