Engineered retaining walls built across Marietta and surrounding neighborhoods. Proper drainage, geogrid, structural block — built to last 30+ years, not 7.
Most Marietta wall projects fall into one of three patterns: (1) terracing a sloped backyard for usable patio + lawn space, (2) reinforcing a failing existing wall the previous owner inherited, (3) building a tall wall along a property line where grade falls off. All three need the same fundamentals: engineered base, drainage, geogrid, structural block.
Marietta retaining-wall work splits between historic neighborhoods near the Square (where charm matters and we hand-select block face) and East Cobb estate yards (where walls are tall, structural, and almost always require PE stamping). We've replaced dozens of failed walls in 1980s–1990s subdivisions where the original installs skipped drainage entirely.
| Tier | Typical Cost | What’s Included |
|---|---|---|
| Decorative / garden border (under 2' tall) | $25–$45 per face foot | Single course of structural SRW, no geogrid, basic drainage |
| Standard 2–4' wall | $45–$80 per face foot | Engineered base, drain pipe + gravel, geotextile, geogrid as needed |
| Tall 4–6' wall | $80–$130 per face foot | Geogrid every 2 courses, full drainage, proper backfill compaction |
| Engineered 6'+ wall (PE-stamped) | $130–$220+ per face foot | Stamped drawings, structural fill, possible tiering, permit coordination |
'Face foot' = wall height × wall length. A 4' tall × 30' long wall = 120 face feet × $80/face foot = $9,600 mid-range. We always quote fixed-fee per project.
| Spec | Cheap Wall | LawnLogic |

| Base material | Native soil | GAB compacted to 95% Proctor |

Decorative under 2': $25–$45/face foot. Standard 2–4': $45–$80/face foot. Tall 4–6': $80–$130/face foot. Engineered 6'+: $130–$220+/face foot.
Yes — Marietta permitting follows standard Cobb/Cherokee/Fulton county rules. Walls over 4' typically require permits, walls over 6' require PE-stamped drawings. We coordinate everything.
Absolutely. Most of our projects are combinations — wall + patio + turf, or wall + outdoor kitchen, or wall + pool surround. We do all of it in-house.
Most residential walls in 3–7 working days. Tall walls or extensive runs: 2–4 weeks. Weather can extend timelines.
Yes — included in any rebuild quote. Teardown, haul-off, engineered rebuild.
Almost always: drainage spec, base depth, block grade, geogrid presence, and engineering. The cheap quote will look identical on day one and lean by year five. See our cost guide for the line-by-line comparison.
