Charlotte Pro Retaining Wall connects homeowners with independent local crews who build segmental block retaining walls across the Charlotte metro. Segmental block — manufactured concrete units that stack and interlock without mortar — is the workhorse of residential walls around Charlotte because it is strong, consistent and comes in many colors and textures.
How segmental block walls work
Each block has a lip, pin or groove that sets it slightly back from the course below. That setback, combined with the weight of the blocks and the gravel behind them, lets the wall lean into the slope it holds. No mortar is used, so the wall can flex slightly as soils move without cracking.
What a proper build includes
- An excavated trench with a compacted crushed-stone leveling pad
- A first course buried below grade so the wall cannot kick out at the toe
- Clean gravel fill in and behind the blocks for drainage
- A perforated drain pipe at the base on most walls
- Cap units glued on top to finish the wall
Choosing a block
Blocks range from smooth, straight-faced units to tumbled, stone-look faces in gray, tan, charcoal and blended colors. Providers can show what local suppliers stock so the wall matches brick, stone veneer or siding on the house.
Typical cost
Most small and mid-size segmental block walls fall within the typical residential range of about $1,500–$5,000. Curves, steps in the wall height, corners and difficult access add labor.
Taller block walls
Taller retaining walls (commonly those over about 4 feet) may require a building permit and an engineered design under local building codes; homeowners should confirm with their city or county. Taller block walls often add reinforcement layers in the backfill as part of that design.
