A Brunswick rock revetment needs a yearly inspection, a look after spring tides, and a check after every tropical storm, so moved stone and washouts are fixed before the bank behind them erodes.

Seawall Repairs by Solid Foundations provides revetment maintenance in Brunswick, GA for riverfront homeowners, HOAs, and commercial and industrial waterfront owners. Typical projects include resetting stone moved by storm surge, rebuilding undercut toes on tidal river banks, repairing torn filter fabric, and fixing washouts where rock meets a bulkhead.

A revetment is a sloped rock bank. Big armor stone sits over smaller stone and filter fabric, and the slope takes the force of waves instead of reflecting it. On a tidal river, it also holds the bank against current. It lasts a long time, but it isn't set-and-forget. Stones shift, fabric gets exposed, and the toe gets undercut a little at a time.
Ends fail first. Current and waves curl around them and dig in behind.
| When | What to check |
|---|---|
| Spring, before hurricane season | Full walk at low tide; reset loose stone; patch fabric |
| After spring tides and king tides | Washout along the highest waterline |
| After any tropical storm or strong nor'easter | Displaced armor, toe scour, end washouts |
| Once a year | Slope shape, transitions, plant growth |
It comes down to how much of the slope the tide covers. The Georgia DNR Coastal Resources Division says coastal tides average about 6½ feet in the marshes and top 10 feet on spring tides (GA DNR CRD). NOAA's Brunswick gauge at Howe Street Pier shows about 7.7 feet between mean higher high water and mean lower low water. Where tides are small, the water works on a narrow band of rock. Here it climbs and drops across most of the slope twice a day, so the whole revetment, from toe to crest, gets worked.
Storms add to that. The Hurricane Center measured 3 to 5 feet of inundation along the Georgia coast during Irma in 2017 (NHC). Surge on top of a high tide pushes waves onto the crest, where stones are often smallest and least tied in.
Work outside the existing footprint on a tidal bank needs CRD review. We keep maintenance inside the footprint where we can and call CRD before starting.
Routine revetment maintenance in Brunswick typically costs $1,500–$5,000 per year for a standard 100-foot residential revetment. Major rehabilitation runs $150–$400 per linear foot.

Our hurricane season seawall prep guide has a pre-storm checklist, and our Brunswick seawall repair page lists every local service. We also maintain revetments in St. Simons Island.
Spring tides can top 10 feet on the Georgia coast. They reach the upper slope, where stones are often smaller and more likely to move.
Call CRD first. Work inside the existing footprint is often handled more simply than expansion, but CRD makes that call.
The rock stops, but the current doesn't. Water curls around the end and scours the softer bank. A planned transition fixes that.
At least once a year, plus after big spring tides and after any tropical storm or strong nor'easter.
