Concrete Services
Structural concrete retaining walls designed for Nashville's grade challenges and clay-heavy soil — built to manage load, channel water, and stand for decades without movement or failure.
Every Project Includes
A concrete retaining wall Nashville property owners can rely on is engineered from the footing up — not just formed and poured. Here's what we include on every project.
Walls over a certain height or in sensitive locations require engineering review. We assess load, surcharge, soil pressure, and drainage requirements before any forming begins — and pull permits where required.
Every structural concrete retaining wall starts with a proper below-grade footing — poured at depth below the frost line, sized for the wall height and the loads it will carry. This is what separates a wall from a decoration.
Hydrostatic pressure is the leading cause of retaining wall failure. We install gravel backfill, filter fabric, and perforated pipe drainage behind every wall — channeling water away from the structure before pressure builds.
Properly designed rebar cage, placed and tied per spec, set in engineered forms. Wall thickness and rebar spacing are calculated for the specific height, backfill depth, and soil conditions of your project.
We use 4,000 PSI minimum for all retaining wall pours. For taller walls or higher-load applications, we step up as needed. Proper consolidation with internal vibrators — no voids left in structural concrete.
Wall face is dampproofed or waterproofed, drain board installed where appropriate, and backfill placed and compacted in lifts — not dumped in and left to settle. Final grade and site cleanup included.
How We Work
Structural walls take more planning and more time than flatwork — here's what to expect from a Cornerstone retaining wall project in Nashville.
Site assessment, load analysis, drainage planning, permit requirements reviewed. Written quote delivered within 48 hours covering full scope.
Excavate to footing depth below frost line, install drainage aggregate, pour and cure footing before wall forming begins.
Forms set and braced, rebar cage installed per spec, concrete placed and consolidated with internal vibrators. Forms stripped after proper cure.
Drain board, filter fabric, and perforated pipe installed. Gravel and soil backfilled in compacted lifts. Final grade, cleanup, and walkthrough.
Transformation
Grade challenges don't solve themselves. A properly engineered concrete retaining wall converts unstable slopes into usable, stable outdoor space.
Significant grade change with active erosion, soil loss during heavy rain, and no usable outdoor space on a sloped Nashville property.
Poured concrete wall with engineered footing, gravel drainage backfill, and weep holes — converting an eroding slope into a stable, usable terrace.
Why Cornerstone
Middle Tennessee's expansive clay soil is one of the most challenging environments for retaining walls in the Southeast. Clay soil holds water — which means hydrostatic pressure behind a retaining wall can be tremendous after a significant rain event. The classic failure mode for under-designed or improperly drained retaining walls is exactly this: a heavy spring rain saturates the backfill, pressure builds against the wall face, and a wall that seemed solid fails suddenly. Our retaining wall designs address this from the beginning: we specify drainage systems that actually drain, backfill materials that don't hold water, and wall designs sized for the soil pressure they'll actually experience — not a generic template.
Many concrete retaining wall Nashville installations include drainage as a cursory check on the material list. We treat drainage as the primary engineering challenge. Behind every wall we build, there is a gravel drainage layer, filter fabric to prevent soil migration into the gravel, a perforated pipe sized and sloped to drain, and weep holes through the wall face as a redundant pressure-relief system. This drainage system doesn't just protect the wall — it protects the property behind it. Poor drainage behind a retaining wall can cause saturation of the adjacent yard, basement moisture intrusion, and foundation problems in addition to eventual wall failure.
In Nashville and surrounding municipalities, retaining walls above 4 feet typically require building permits and sometimes engineering drawings. We navigate this process on your behalf — assessing what's required for your specific project, preparing or coordinating required documentation, and pulling permits before work begins. This protects you from liability and ensures that inspections happen correctly. We've built retaining walls across the Nashville metro under a variety of permit conditions, and we know exactly what each jurisdiction expects. When you hire Cornerstone for a concrete retaining wall Nashville project, the permitting process is handled, not passed off to you.
