A retaining wall does real structural work: it holds back tons of soil and water on Knoxville’s hilly, clay-heavy lots. That’s why a wall built without proper base, backfill and drainage will lean, bulge and eventually blow out — usually after the first few heavy East Tennessee rains.
We build retaining walls that are engineered from the footing up, with the drainage behind them that most failed walls never had.
Wall types we build
- Segmental block walls (Belgard, Techo-Bloc and similar systems)
- Natural stone and boulder walls
- Seat walls and garden walls
- Tiered walls for steeper grades
Why our walls hold
- Proper footing and compacted base
- Clean, free-draining backfill — not the excavated clay
- Drainage pipe and gravel behind the wall to relieve water pressure
- Geogrid soil reinforcement on taller walls
- Batter (set-back) and compaction lift by lift
What it costs
Retaining walls in Knoxville typically start around $48 and run up to $65+ per face square foot depending on wall type, height, drainage and whether engineering/geogrid is required. Taller walls (generally over 4 ft) may require an engineered design and permit.
