Concrete Walls

Walls are the most demanding concrete work we do, because a wall is holding something back. We build retaining walls, poured foundation walls, stem walls, segmental block walls and structural concrete walls across Charlotte and Gaston County — engineered for the actual load, drained properly behind the face, and built to stay plumb for decades.

The number one killer of retaining walls is not soil weight. It is water. Saturated soil behind a wall can nearly double the lateral pressure it exerts, and a wall designed for dry backfill will bow, lean or fail outright once water has nowhere to go.

Every retaining wall we build gets a drainage system: clean angular drainage stone directly behind the face, filter fabric to keep fine soil from migrating into and clogging that stone, and a perforated drain pipe at the base daylighted to a location where water can actually escape. It is largely invisible once the job is done, which is exactly why it is the first thing cut by a cheaper bid.

If you have ever seen a wall in a neighborhood bulging outward in the middle, you have seen what happens when it is left out.

In most local jurisdictions, retaining walls over four feet in exposed height require an engineered design and a permit. So do shorter walls carrying a surcharge — a driveway, a parking area, a pool, a structure, or a slope continuing to rise above the top of the wall.

We will tell you plainly which category your project falls into. If it needs engineering, we build to the stamped design and coordinate the inspection. What we will not do is build a tall unengineered wall because it is cheaper today, and leave you with a structure that is both a liability and a future demolition bill.

Poured concrete walls are the right answer for foundation walls, basement walls, tall structural walls and anywhere you need maximum strength in minimum thickness. They are monolithic, they can be reinforced heavily, and they can be waterproofed as a continuous surface.

Segmental block — the interlocking units you see in landscape walls — is often better for tiered garden walls, gentle grade changes and curved layouts. It is flexible, tolerates minor settlement without cracking, and can be built with geogrid layers extending back into the soil so the reinforced soil mass does much of the work.

Which one is right depends on height, load, drainage, and honestly the look you want. We will walk you through both rather than quoting whichever one we happen to prefer building.

A lot of properties around Charlotte and up toward Gastonia have significant grade change. Where a single tall wall would be expensive and visually heavy, two or three shorter terraced walls often work better — less lateral load on any one structure, more usable flat area created, and a far better look.

Terracing has its own rule that gets ignored constantly: the walls have to be spaced far enough apart that the upper wall is not surcharging the lower one. Stack them too close and you have effectively built one tall wall with a weak point in the middle. We space them properly and reinforce accordingly.
