Excavating Contractor in Stoneboro, PA

The Sheffield-Platea soils common in this part of Mercer County are nearly level and very poorly drained, with a water table that sits close to the surface during wet seasons. Water that enters the soil moves slowly and can keep the ground saturated for extended periods. A French drain system installed at the right depth intercepts that water and routes it to a proper outlet.

It depends on the water table depth and the soil's percolation rate at your specific location. Mercer County requires a soil evaluation before any septic permit is issued. Lots with a high water table or very slow percolation may require an elevated mound system or another alternative design. We assess the site and work within what the soil and county requirements allow.

Almost certainly. Soft spots and ruts on a flat lot in this area are typically caused by water saturating the base material because there is no drainage layer beneath the surface. The fix is to excavate the affected section, install proper drainage, and rebuild the base before resurfacing. Patching the surface without addressing the base will produce the same result within a season or two.

Yes. On flat lots where the natural grade offers little drainage, we regrade the surface to direct water away from the foundation and toward a drainage outlet. Combined with French drains where needed, proper grading is one of the most effective ways to manage water on Mercer County's low-lying properties.
