Excavation & Retaining Wall Repair in Wausau, WI
A Small, Local Crew Serving Wausau Homeowners and Property Owners

Straightforward Sitework for Wausau Properties
Wausau has plenty of older neighborhoods with rock and fieldstone retaining walls that are starting to show their age — cracked mortar, bowing sections, caps that are pulling apart. Thomas Excavation repairs and replaces these walls throughout Wausau, along with excavation, demolition, and site work for both residential and larger private projects. We're a small, hands-on crew based just outside town in Aniwa — not a large regional outfit — and we treat every Wausau job, big or small, the same way.
Our Core Services

Featured Service: Retaining Wall Repair
If your retaining wall has cracked mortar, a failing cap, or a section that's starting to bow, it's worth having it looked at before a manageable repair turns into a full rebuild. We repair aging fieldstone walls and, where a wall is too far gone to patch, replace them with modern engineered block systems built to handle Wisconsin's freeze-thaw cycles for decades.

Excavation
Foundation, basement, and grading excavation for Wausau homeowners and builders. We can also incorporate clay lining on retention ponds and drainage work where it's called for.

Retention Pond Construction
Excavated and shaped retention ponds for water management, including clay lining when the project calls for it.

Demolition
Structure and site demolition, debris removal, and lot clearing for Wausau properties — from a single old outbuilding to a larger private teardown.

Lot Clearing
Tree, brush, and stump removal for Wausau properties, whether you're opening up a building site or reclaiming overgrown acreage.

Driveway Installation
Gravel and base-prep driveway work for Wausau-area properties, from short residential drives to longer private lanes.
Why Wausau Property Owners Choose Thomas Excavation
- Local, not corporate. We're a small crew based right outside Wausau — you'll talk to the person doing the work, not a call center.
- No job too big or too small. A single failing retaining wall gets the same attention as a larger private excavation project.
- Straightforward pricing. You'll know what a job costs and what to expect before we start.
- Built for Wisconsin weather. We know what freeze-thaw cycles do to a wall, a driveway, or a foundation here.
