Trenchless Pipe Bursting
H&H Contractors offers comprehensive trenchless solutions to your underground utility problems at a competitive cost. We can deliver pipebursting, sliplining and directional drilling, which gives you an alternative to open cutting through sensitive areas.
Our pipebursting method replaces existing pipe by sending a pneumatic missile shaped “Jackhammer” to break up the existing pipe. Bolted onto the back of this tool is HDPE (high density polyethylene) pipe. A heavy duty winch has a cable attached to the front end of the tool and it guides it along the existing or “host” pipe.
The “host” pipe or the existing pipe in the ground has a winch cable pulled through it and that is attached to the end of the pipeburster. The cable goes through a couple of pulleys in the pulley mast and when the winch is turned on it provides a steady even pulling force that ensures the pipeburst stays on course through the “host” pipe.
The existing “host” pipe is destroyed and the small pieces get pushed into the surrounding ground.
H&H use the Grundomat horizontal boring and more detail on this tool can be found here.
