Dunnebacke Constructors
Drainage & Erosion Control · Hendersonville, TN
Tennessee hillsides are beautiful until they start sliding into your yard. Dunnebacke Constructors builds retaining walls in Hendersonville that hold — designed around drainage first, built to last, and sized correctly for your slope and soil conditions. No shortcuts, no walls that fail in the first hard rain.
A retaining wall is only as good as the drainage behind it. Most retaining wall failures in Tennessee happen not because the wall material was wrong, but because water was never properly managed behind the structure. It builds up, the hydrostatic pressure grows, and the wall moves or collapses.
At Dunnebacke Constructors, drainage is our core specialty — and that's exactly why our retaining walls last. We don't just stack rock or set block; we design and build walls with proper drainage behind them from the start. That means gravel backfill, drainage fabric, weep holes or drain pipes where needed, and proper grading to direct water away from the wall face.
Riprap — large angular stone placed along slopes and banks — is one of the most durable and cost-effective solutions for slope stabilization in Tennessee. We use it for everything from roadside banks to drainage channel armoring to full slope retention.
For cleaner, more finished retaining walls — around driveways, patios, or tiered yards — we build with concrete block or natural stone. These give you a defined edge and can handle significant grade changes.
We walk your property, evaluate the slope, soil type, and where water is coming from. Before we talk about wall design, we talk about drainage — because that determines everything.
Proper wall footings matter. We excavate to solid bearing, set appropriate base material, and ensure the wall starts level and true. This is where cheap jobs cut corners — we don't.
As we build, we install drainage fabric, gravel backfill, and drain pipes or weep holes behind the wall face. Water has to go somewhere — we make sure it goes through the wall, not against it.
Once the wall is set, we grade the backfill area, compact it properly, and restore the slope above with seed and straw if needed. A finished job that doesn't erode immediately after.
The #1 cause of retaining wall failure in Tennessee is hydrostatic pressure from water that has nowhere to go. Our drainage-first approach means every wall we build handles the water correctly — not just the soil. That's the difference between a wall that lasts decades and one that fails in a wet spring.
Water management is our core expertise. Our retaining walls are designed around drainage from day one.
We've placed riprap and rock walls across Sumner County. We know how to source, place, and set stone correctly.
Austyn runs every project personally. No crew you've never met showing up — you know who's doing the work.
We don't build walls that look good in photos and fail in a year. We build walls that hold through wet Tennessee winters.
Retaining wall cost varies significantly based on wall height, length, material, terrain, and drainage requirements. Riprap slopes are typically more economical for large areas; block walls cost more per foot but give a finished look. We provide free on-site estimates — call (615) 887-1194 to schedule yours.
Walls over a certain height (typically 4 feet in most jurisdictions) may require a permit in Hendersonville and Sumner County. We recommend checking with the City of Hendersonville or Sumner County building department before starting. We can help guide you through the process.
Most retaining wall failures come down to two things: inadequate drainage behind the wall, or an undersized footing. Water builds up behind the wall, the pressure grows, and eventually something gives. We address both issues in every wall we build.
Yes. Steep slopes often need tiered walls rather than one tall wall — multiple shorter walls step the grade and distribute the load more safely. We assess the slope and recommend the best approach during the estimate.
