Our Excavation & Backfilling Process

Our team performs all phases of your foundation excavation or utility trenching, beginning with surface digging, soil removal, and removal of below-grade rocks. We can also prepare the site by bringing it to proper elevation and grade.

Once all required site work is complete, we will backfill the groundwork using high-quality stone and fill materials. Compaction and grading are carefully executed and tested to ensure long-term stability and compliance with your project specifications.

With an extensive fleet of modern equipment including excavators, loaders, skid-steers, and dozers, LaRosa ensures that your excavating services are completed efficiently, keeping the project on schedule.

Throughout the process, all work is performed in strict accordance with OSHA requirements and local and state regulations. Safety is always our top priority.


Successful construction projects begin with safe, stable foundations. With 70+ years of experience, you can trust LaRosa to get your excavating services done right the first time.
