Foundation Excavation

Square, level, and on schedule. Precision dig-outs for homes, additions, and commercial structures.

The dig that the whole building rests on

Foundation excavation isn't forgiving. An out-of-square hole, a bad bearing elevation, or a shortcut on bedding — any of those compromise the structure that gets built on top. Blair Excavation Inc. handles foundation excavation for new residential and commercial builds, additions, and basement projects in Lakewood, IL and across the greater Chicago area. We dig them clean, we dig them level, and we dig them on schedule.

We work directly with homeowners, general contractors, custom builders, and designers. Whether it's a single-family basement, a slab-on-grade footprint, a tight addition hole, or a commercial foundation, we bring the equipment and the eye for detail that structural work demands.

Foundation services we provide

  • New foundation excavation — full-depth digs for basements, crawl spaces, and slab foundations.
  • Addition excavation — careful work next to existing structures to avoid undermining.
  • Footing excavation — trenched footings to precise depth and width per engineered plans.
  • Commercial foundation digs — larger-footprint excavation for retail, office, and light-industrial sites.
  • Backfill & grading around foundations — proper fill, compaction, and positive grade to move water away from the structure.

Why accuracy matters

When we dig a foundation, we're setting the elevation that concrete crews, framers, and every trade after them will build off of. Get the elevation wrong and everyone downstream eats the cost. Get it right and the project runs smooth. We shoot accurate elevations, cut clean to plan, and hand off a hole that your foundation contractor can form in right away.

Built around your build schedule

Construction schedules are tight. Weather, inspections, and concrete availability all move. We communicate with the GC, adjust when needed, and show up ready to work. No calls on Monday morning wondering where the excavator is.
