Retaining Walls in
O'Hara Township
O'Hara Township sits adjacent to Fox Chapel and shares much of the same wooded, ridge-and-valley terrain. The retaining wall projects here range from refined garden walls in Aspinwall-adjacent neighborhoods to substantial engineered systems on the larger ridge-top properties — all of them sharing the same fundamental drainage challenges.
What we build for O'Hara Township homeowners
Segmental Block Walls
Versa-Lok and Allan Block walls — the modern standard for residential properties.
Boulder Walls
Natural stone walls that complement the local landscape character.
Poured Concrete
Engineered concrete walls when you need maximum height or strength.
Engineered Tall Walls
Walls over 4 ft requiring stamped engineering — we handle permits and PE coordination.
Why O'Hara Township needs walls done right
Stream valleys and wooded ridges are gorgeous and brutal on retaining walls. Surface water from above the property, groundwater seeping through the hillside, and root pressure from mature trees all conspire to test any wall that wasn't built with drainage as the first priority. In O'Hara we plan the drainage chimney and daylight discharge before we plan the block — because if the water can't get out, the block layout doesn't matter.
