What are Trenchless Technologies?

Trenchless technologies are non-invasive methods of installing, repairing, or maintaining water and sewer pipes, that do not require digging. Perfect for areas with patios, driveways, walkways, etc.

Why go Trenchless?
  • Going trenchless means we won’t have to excavate your yard or business area: If any digging or drilling is needed, it will be minimally invasive.
  • It’s cheaper compared to digging: Besides the costs for excavating the work area, you’d also have to pay to get your yard back to looking normal; this isn’t an issue with trenchless methods!
  • It’s faster: Because there is less equipment involved, there is less time required to set up. The job can be finished same day!

Our Trenchless Services

Directional Drilling

We install a brand new pipe by drilling the pipe into place from a single point.

Pipe Bursting

A new pipe is pulled through an existing old or broken pipe, pushing it out of the way and replacing it.

Pipe Lining

An epoxy lining is inserted into the old pipe, expanded, and cured in-place, essentially creating a new pipe inside of the old one.
