In-ground swimming pool excavation for residential and commercial properties. Precise depth, clean walls, full spoil removal, and site preparation for the pool crew.
Backwell excavates in-ground swimming pools for residential and commercial properties throughout Marathon, Cortland County, and the surrounding area. Pool excavation requires precision — the hole needs to be the right depth and dimensions, walls need to be clean and stable, and all spoil needs to be removed from the site before the pool contractor arrives. We work directly with pool companies and homeowners to ensure the dig is done right the first time.
We handle pools of all shapes and sizes including vinyl liner, fiberglass, and gunite pools. Our operators are experienced with the precision required for pool work — setting grades, maintaining clean walls, avoiding damage to access routes, and removing spoil efficiently. We also handle all associated site preparation including access clearing, spoil hauling, and rough grading after installation.

Marathon lies in the Tioughnioga River valley in southern Cortland County, on a narrow outwash-floored corridor cut into the Appalachian Plateau. The valley floor carries Chenango gravelly loam and Howard gravelly loam — well-drained and cobble-rich — while the valley walls climb steeply into Lordstown and Mardin channery silt loams on fractured sandstone and siltstone.
The Tioughnioga River runs through the village and drains south toward the Susquehanna, and the valley's sole-source aquifer status imposes stricter stormwater and infiltration protection on any commercial project. Site work in Marathon consistently involves cobble-heavy trenching in the outwash, rock excavation on the valley walls where development climbs out of town, and floodplain management along the river corridor. The I-81 interchange area sees most of the commercial activity, and earthwork there typically requires aquifer-protection measures as well as standard erosion and sediment controls. Frost depth is substantial given the upstate interior climate. Projects near the Tioughnioga River fall under NYSDEC stream-protection review in addition to municipal permitting, and the narrow valley limits lay-down area on most commercial sites.
