Retaining Walls that hold the hill.
A hillside you cannot use is wasted property. We build poured concrete retaining walls that hold the slope, level the yard, and turn the steepest part of your lot into space you actually use.
What You Get
Every wall starts with the ground. We cut the site, pour a footing sized for the load, and set steel before a drop of concrete shows up. And the wall itself is only half the job. Water is what kills retaining walls in Pennsylvania, so drainage goes in behind every one we build: stone, pipe, and a path out.
The person who quotes your wall runs the crew that builds it. One crew from the first cut to the final grade, and the quote you sign is the number you pay.
We serve homeowners and businesses across Greene County, Washington County, Allegheny County, and Fayette County. The walk-through quote is free.
