Since 1983, the Putnam family and JABAR Corporation have served an expanding territory of municipal and private customers with pipe bursting and water infrastructure installation needs.

Today, the firm has a global reach, with its team providing expertise on difficult pipe bursting scenarios and offering its patented pipe bursting machines to clients around the world.


Founded in 1983, Louisiana-based pipe bursting contractor JABAR has completed pulls in 30 U.S. states and consulted around the world on the most difficult pipe bursting scenarios.

Using patented pipe bursting equipment from its Innovative Trenchless Systems division, JABAR has achieved a record of speed, safety and cost savings that make it the go-to source for getting jobs done right.

The engineering expertise and practical experience of the team at JABAR has led to the development of nine patents, with an additional patent pending.
