Recently, our crew wrapped up a complete house site in Bethany, handling everything from start to finish. The project included stripping the topsoil, cutting in the driveway, excavating the foundation, preparing for the basement floor, installing the septic system and well line, trenching for electrical, installing a process driveway, and spreading the topsoil to finish the site.

From the initial excavation to the final grading, we have the equipment, experience, and knowledge to handle every step of your house site project.

Last week, our crew was in Hamden installing a 6” curtain drain and catch basin, tying into the existing drainage system on site. This project came with several challenges, including working in a tight space alongside an existing building, maintaining pedestrian access along an active sidewalk, removing a section of concrete sidewalk, and keeping the driveway open to ensure continued access to the businesses in the building.

Despite the challenges, our team got the job done efficiently and professionally, restoring the work area and leaving the site looking like we were never there. Another project completed from start to finish!

Last week, our team installed risers and serviced a septic tank located beneath an asphalt driveway. This tank had never been serviced before!

We started by locating the tank with our locating equipment, then carefully excavated the area to expose it. After installing the risers, we used 1¼-inch process stone to bring the grade up to subgrade for paving. We then compacted the area to help prevent future settling before repaving the disturbed section of the driveway.

We take pride in doing the job right from start to finish, leaving the area looking like we were never there!

Yesterday, one of our crews was in Monroe replacing an old homemade cinder block septic tank with a new Roth septic tank backed by a lifetime warranty. We backfilled the tank and pipes with stone to help prevent settling and ensure a solid installation. Once the work was complete, we restored the lawn with topsoil, seed, and hay. Another job completed in just one day to minimize downtime to the homeowner
