01

Excavation Services in Kennewick

We handle excavation for new homes, garages, shops and additions throughout Kennewick, cutting to the elevations on your plans and leaving a level, buildable site. From a small addition to a full homesite, the goal is a stable, well-drained base that lets your build start right.

We work from your plans and coordinate with your builder so excavation stays on schedule.

Site Preparation and Grading

We clear and grade building pads, balance cut and fill, and establish drainage that carries water away from the structure. Proper grading helps prevent the settling and ponding that show up later on pads that were not compacted or sloped correctly.

Foundation and Basement Excavation

We excavate for full basements, crawlspaces and footing trenches to the depth and elevation your plans call for, accounting for bearing soil and local frost depth. Every dig is backfilled with the right material and compacted for the forming crew and inspector.

02

Soil and Site Conditions in Kennewick

Kennewick sits on Columbia Basin soils that range from sandy and well-drained to silty ground that holds water. The right approach to excavation and drainage depends on what is actually in the ground, and we plan for the conditions we know to expect.

We plan drainage first, size foundations and trenches to the actual soil, and bring the right equipment for the ground.

03

Trenching and Utilities in Kennewick

We trench for water, sewer, electrical and communications lines throughout Kennewick, digging to the depths required by code and utility standards and bedding and backfilling so the trench does not settle. We arrange 811 locates before any trenching and coordinate connections with the utility companies.

Where municipal water and sewer are available, we install and connect the laterals that tie your property to the main.

04

Demolition and Site Clearing in Kennewick

When a structure has to come down so something new can go up, we handle residential and light commercial demolition, concrete and slab removal, and site clearing throughout Kennewick. We plan the safe sequence, protect the utilities you are keeping, and haul off the debris.

Because we also excavate and grade, we can take a Kennewick project from demolition straight through to a level, buildable site without a second crew.
