Why Trust Our Foundation Excavation in Lebanon, NH?

Lebanon sits where the Connecticut and Mascoma Rivers meet, in a valley that was once submerged under glacial Lake Hitchcock. That history left behind thick, fine-grained lake-bed clay and silt across much of the valley floor — soil that holds water, drains slowly, and can be soft or unstable well below the surface.

That’s the starting point. What comes after it is where local knowledge matters.

Lebanon also sits near the Ammonoosuc fault line, where distinct rock formations meet close together rather than transitioning gradually across miles. That means bedrock depth can shift sharply from one lot to the next — soft lake clay in one spot, shallow ledge just down the street. A foundation excavation planned without accounting for that can run into wet, unstable soil or unexpected rock removal mid-project.

Along the I-89 and Route 120 corridor, from West Lebanon’s river valley to the upland terrain elsewhere in the city, we’ve excavated foundations across ground that changes character block by block.

Murphy & Son Construction Inc. has excavated foundations across the Upper Valley for years. We know what’s under Lebanon before we start digging.

 Trustindex verifies that the original source of the review is Google. Jon and his team are awesome! Over the years, they have completed a variety of projects for me and my neighbors, including the removal of many dead and dying trees (along with their stumps), the complete renovation of our common road, which was in a state of disrepair due to a lack of proper maintenance, and the repair of my driveway. Most recently, removing a rock wall with many large dead trees embedded in it, and clearing the entire area to create outdoor gardens, and coordinating that effort with adding buried conduit to repair a direct-bury electric connection to the well head, as well as installing conduit for a solar array. Additionally, Jon and his team plow my driveway and the common road shared with my neighbors. They come just often enough to keep us always open, and are very careful not to plow the road so deep as to move the gravel onto the lawn. Always fair pricing, great attention to detail, and an absolute pleasure to work with. Can't recommend enough.

What Makes Our Foundation Excavation in Lebanon, NH Efficient and Reliable?

Excavating a foundation in Lebanon starts with knowing which version of the ground you’re dealing with — not assuming it’s the same as the lot next door.

Site assessment comes first. We evaluate soil composition, water table depth, and bedrock indicators specific to your property, because valley-floor clay and upland ledge require different equipment, timelines, and dewatering plans.

From there, we confirm frost depth and foundation specifications for your project and plan the excavation approach around what the site actually presents — whether that’s managing soft, wet clay or working around shallow rock.

Excavation proceeds to the required depth and footprint for your foundation plan. Where clay soil is present, we address drainage as part of the excavation, not as a problem left for the framing crew to discover later. Where bedrock is shallower than expected, we adjust equipment and approach rather than treating it as a costly surprise.

Spoil is managed as we go, backfill is compacted properly, and final grade is set to keep water moving away from the foundation, not toward it.

Case Studies

A homebuilder near the Connecticut River in West Lebanon needed foundation excavation on a lot with soft, clay-heavy lake-bed soil. We assessed water table depth and soil stability before excavating, managed dewatering through the process, and delivered a stable, properly drained foundation pad ready for the concrete crew with no delays.

A property owner along the I-89 corridor needed foundation excavation on a lot where bedrock sat closer to the surface than the initial soil survey suggested. Pre-excavation assessment identified the shallow ledge, we adjusted equipment and approach accordingly, and reached proper bearing depth without a mid-project change order surprise.
