Our Excavation Services

What we offer

From breaking ground to final grading, SGW Excavation handles every phase of site development. We provide comprehensive excavation services for residential and commercial projects, bringing the right equipment and experience to each job.

Stump Removal

We remove vegetation, stumps, and roots to prepare your property for construction. Our equipment and experience allow us to handle projects of all sizes.

Foundation Excavation

Proper foundation work requires precision to ensure your building starts on solid ground. We dig foundations for new homes, additions, garages, and commercial buildings, working closely with your builder to ensure proper depth, dimensions, and drainage.

Septic System Installation

We handle all excavation work for septic installations, including tank placement, leach field preparation, and proper grading for drainage. We coordinate with septic designers to ensure your system is installed correctly.

Utility Line Trenching

We dig trenches for water lines, electrical conduit, and gas lines. Our experience includes new construction installations and service upgrades for existing properties, coordinating with utility companies and other contractors to keep your project on schedule.

Ledge Removal

When rock is encountered, we coordinate with licensed blasting contractors to safely remove it and keep your project moving forward. Our experience means we can anticipate and address these challenges efficiently.

Driveway & Road Construction

We handle complete driveway and road construction, including excavation, base preparation, grading, and coordination with paving contractors. From new driveways to private roads for developments, we manage the entire process.

Paving

We provide asphalt paving for driveways, parking areas, and private roads. Our paving services ensure a smooth transition from excavation through final surface installation, with one contractor managing the entire process.

Hydroseeding

We provide hydroseeding to establish vegetation quickly and prevent soil erosion. It’s an efficient, cost-effective method for establishing grass and ground cover on new construction sites, slopes, and disturbed areas.
