Retaining Wall Repair & Replacement in Wausau, WI

Fixing Failing Rock, Fieldstone, and Block Walls Throughout Central Wisconsin

Wausau's older neighborhoods have no shortage of rock and fieldstone retaining walls — many of them decades old, and many of them starting to show it. Cracked mortar, bowing sections, and caps that are pulling apart aren't just cosmetic issues; they're signs a wall is failing and needs attention before it gives way. Thomas Excavation repairs and replaces retaining walls throughout Wausau and Central Wisconsin, from small residential jobs to larger private projects.

The Problem: Why Old Retaining Walls Fail

Wisconsin's freeze-thaw cycles are hard on masonry. Water gets into small cracks in the mortar, freezes, expands, and widens the crack a little more every winter. Over years, that process turns a small crack into a bowing wall, a crumbling cap, or a section that's separated from the rest of the wall entirely.


Common signs a retaining wall needs attention:


  • Cracked or crumbling mortar between stones
  • A wall that's visibly leaning or bowing outward
  • A concrete cap that's cracked, lifting, or missing sections
  • Gaps opening up between the wall and the ground behind it
  • Water pooling at the base of the wall instead of draining away


If your wall shows any of these signs, it's worth having it looked at before a minor repair turns into a full rebuild.

The Solution: Modern Engineered Retaining Walls

For walls that are too far gone to patch, we replace them with engineered modular block systems — a style that's become increasingly common throughout Wausau. These large, rock-textured blocks interlock for strength, handle Wisconsin's freeze-thaw cycles far better than old mortared stone, and give a clean, finished look that holds up for decades.
