What Is Excavation?

Site Work Solutions runs excavation across San Antonio and the surrounding Hill Country — the dig work behind foundations, utilities, septics, pools, drainage, and ponds. Modern equipment, proper shoring where depth requires it, and a 24/7 phone line for the times the job can't wait.

Excavation covers a wide spectrum of digging work. Foundation excavation cuts the footprint for new homes, shops, and barns down to the spec depth — typically slab-on-grade in this market, occasionally pier-and-beam, and very rarely full basements (the soils don't favor them here). Utility trenching runs the linear cuts for water, sewer, electric, fiber, and gas. Septic excavation handles tank pits, drain field trenches, and inspection cleanup. Pool excavation is the dig-and-spoils phase before your pool builder takes over.

On rural work we add drainage channels, swales, pond shaping, and stock tank work — the kind of jobs that ask for a sense of how water moves across Texas terrain. On commercial sites we handle smaller foundations, parking lot subgrade excavation, retention pond shaping, and tie-ins. We don't chase massive earthwork that would dilute the bench — we run the small-to-mid range exceptionally well.

San Antonio soils are unforgiving in two directions. North and west of town you hit limestone and caliche that will blunt a digging bucket and call for hydraulic breaker (hoe ram) work. East and south you find expansive clay that swells when wet and shrinks when dry — critical to know before you backfill a foundation. We plan for both before the machine shows up.
