Retaining Wall Construction in Angier, Wake County and Across the Triangle
Engineered block, stone, and timber walls with the drainage behind them done right.
Retaining Wall Construction in Angier, Wake County and Across the Triangle
Engineered block, stone and timber walls with real drainage behind them, built to hold for decades.
Segmental Block Walls
Interlocking concrete block is the workhorse of modern retaining walls. Each course steps back so the wall leans into the hill instead of fighting it, and we backfill with clean stone and drain tile so water never builds up behind it. Taller walls get geogrid tied into the soil for real structural strength.

Stone Backfill & Drain Tile Behind Every Wall
Natural Stone Walls
When you want the wall to look like it grew out of the property, stone is the answer. We build dry-stacked and mortared walls in fieldstone, boulder, and cut stone, fitting each piece so the face reads natural instead of repetitive. No two walls come out the same.

Timber & Landscape Walls
For shorter garden walls and planting beds, pressure-treated timber is quick to build and easy on the budget. We pin the courses with rebar and set deadmen back into the bank so the wall stays put instead of bowing out after a couple of seasons.

Drainage & Erosion Control
Water is what kills retaining walls and yards. Every wall we build gets clean stone backfill and drain tile behind it, but we also handle the bigger picture — french drains, catch basins, downspout tie-ins, and regrading so runoff leaves the property instead of pooling against your wall or your foundation.

Terracing & Usable Yard Space
A steep slope is wasted yard. We break a hillside into flat, usable levels with stepped walls, turning ground you could barely walk on into lawn, patio space, and planting terraces. Steps tie the levels together so the whole yard is easy to move through instead of something you look at from the deck.

Wall Repair & Replacement
A wall that's leaning, bulging, or blown out in one section is telling you the base or the drainage failed. We dig back, find the actual cause, and rebuild it right instead of stacking the block back up and hoping. When a wall is too far gone, we tear it out and replace it with one that will last.

A block wall going in: drainage pipe, gravel backfill and geogrid behind the block. This is the part you never see once the wall is finished, and the part that decides whether it is still straight in ten years.
Retaining Walls Built Across Harnett, Wake and Johnston Counties
Keystone builds and repairs retaining walls in Angier, Lillington, Coats, Dunn, Fuquay-Varina, Holly Springs, Willow Spring, Apex, Cary, Garner and Clayton, North Carolina. Most of this area is red clay over a slope, which is why so many walls here fail the same way: water gets behind the block and has nowhere to go. Every wall we build is designed around where that water is going to end up.
What Affects the Cost of a Retaining Wall
Wall pricing is driven by height and length, the block or stone you choose, how much excavation the site needs, how the machine gets to the work, and how much drainage stone, pipe and geogrid the wall has to carry behind it. A taller wall, or one holding back a driveway or structure, can need an engineered design. Replacing a failed wall also means removing the old one and fixing whatever caused it to move in the first place. All of it is itemized in the written estimate.
