A retaining wall stays up when it has a compacted base, drainage stone and pipe behind it, and geogrid on taller walls. Taller walls usually need a permit and engineering; Providence exempts walls only up to four feet. Old fieldstone walls can often be rebuilt from their own stone.

Walls fail from water, not weight. A leaning wall almost always had nowhere for the water to go.
| Element | Why |
|---|---|
| Compacted base | Keeps the first course level |
| Drainage stone and pipe | Relieves water pressure behind the wall |
| Batter (lean into the hill) | Resists the soil's push |
| Geogrid | Ties taller walls into the slope |
| Permit and engineering | Taller walls or walls holding a driveway or slope above |
Dry-laid fieldstone walls line New England roads and yards. Many can be rebuilt from their own stone. In Newport's historic districts, most walls are exempt from review, but historic stone walls are governed separately; ask the city first.
We're a referral service: one local crew gets your request and quotes in writing.
Often for taller walls; Providence exempts walls up to 4 feet from the bottom of the footing unless they hold a surcharge. Check your town.
Usually water pressure behind it, a weak base, or no geogrid on a tall wall.
Often from the original stone; it's skilled work worth asking about.
Tell us the address and what you want to build. One local crew based in Bristol sees it, sketches it and puts design and price in writing.
Plain, sourced answers about patios, walls and steps in Bristol and the East Bay, and one introduction to a local crew when you're ready to build.
East Bay Hardscape is an independent referral service, not a contractor. We don't build, schedule or price work; the local crew we connect you with handles all of that directly with you and is responsible for its own registration, insurance and permits. We are not lawyers; permit information is general.
