Hardscape & Patio base prep.
The patio you see is only as good as the base you do not. We excavate and compact the ground under patios, walkways, and hardscapes so nothing settles, shifts, or heaves after the first winter.
What You Get
Most patio failures are base failures. Shallow excavation, soft spots, no compaction: the pavers look fine in July and start moving in January. Pennsylvania freeze and thaw is not forgiving.
We dig to the right depth, haul out what comes out, bring in the right stone, and compact it in lifts. When your hardscaper starts, the ground under the project is already done right.
We serve homeowners and businesses across Greene County, Washington County, Allegheny County, and Fayette County. The walk-through quote is free.
