Rock & ledge excavation

Around Mendham Township, we deal with a lot of ledge rock

Mendham Township sits in the New Jersey Highlands, where the bedrock is ancient, hard gneiss and granite that often sits close to the surface. Because that rock resists erosion, digging here regularly runs into ledge, and it takes the right equipment to get through it.

We bring in the bigger machines and the tools to break out and remove ledge rock so the job keeps moving, whether it is a foundation, a utility trench, or a septic field. Rocky ground is where experience really shows. That is a big part of what we do here, but it is far from the only thing. We still handle sewer and water lines, septic, grading, driveways, and emergency digs across town.

Morris County runs from busy suburban neighborhoods to wooded hillsides, and the work follows suit, from tight utility repairs to regrading sloped lots that will not drain.

As a township, Mendham Township has the kind of larger properties where septic systems, grading, drainage, land clearing, and long driveways come up most. Whether it is an emergency sewer or water line dig-out, a septic system, a lot that will not drain, or a new driveway, we bring our own equipment and an operator who knows the ground in this part of Morris County. We show up when we say we will, and we leave your property graded and clean.
