Mountain driveways aren't like flatland driveways. Gravity, rain, freeze-thaw, and heavy use conspire to wash out gravel, erode edges, create ruts, and undermine surfaces. If your driveway is a problem every time it rains, you need more than a load of gravel dumped on top.
Terra Builders AVL has been grading and repairing mountain driveways for 17 years. We fix the underlying drainage and grade issues so your driveway stays put.
Driveway Services
Gravel Driveway Grading — Reshape and compact your existing gravel drive. We establish proper crown (high center for drainage), fill ruts and potholes, and add material where needed.
Driveway Drainage — The #1 cause of driveway failure on mountain properties is water running down the drive instead of off it. We install cross-drains, French drains, swales, and proper grading to redirect water.
Culvert Installation & Repair — Where water crosses your driveway path, you need culverts. We size and install corrugated metal and HDPE culverts with proper headwalls and wingwalls.
Steep Driveway Solutions — Asheville driveways regularly exceed 15% grade. We manage steep drives with: - Terraced gravel sections with cross-drains at each transition - Concrete tire strips on the steepest pitches - Proper base material that won't migrate downhill - Turnarounds where the drive is too steep to back out
Driveway Base Prep — If you're paving (asphalt or concrete), the base determines everything. We grade, compact, and verify base material to spec before the paving crew arrives.
New Driveway Construction — From raw land to finished drive. We clear the path, grade the route, install drainage, build the base, and surface with your choice of material.
Common Mountain Driveway Problems
- Washboard ruts from water channeling down the center — fix: crown grading + cross-drains
- Edge erosion where shoulders wash away — fix: ditch grading + gravel shoulders + drainage pipe
- Pothole clusters from poor base material — fix: excavate soft spots + rebase with crusher run
- Washout at the bottom where slope water accumulates — fix: culvert + catch basin + redirect
- Ice buildup on north-facing steep sections — fix: drainage improvements + material selection
Materials We Use
- #57 stone — Clean drainage aggregate for base and sub-base
- Crusher run (ABC stone) — Compacts tight for driving surface
- #4 stone — Heavy base material for steep grades
- Recycled asphalt — Affordable, compacts well, binds in heat
- River rock — Decorative but impractical for driving (we'll talk you out of it)
Why Drainage Is the Real Fix
Every driveway problem on a mountain property is actually a drainage problem. Gravel doesn't wash away on flat ground. Edges don't erode without water. Potholes don't form in well-drained base.
If someone just dumps gravel on your problem, you'll be calling again in 6 months. We fix the water first, then fix the surface.
