Wall systems
Poured Concrete Retaining Walls
When a wall is holding up a driveway, a pool deck, or a structure — not just a slope — poured concrete is usually the right call. It's the wall system we reach for on taller, load-bearing, and engineered projects across Martin and St. Lucie counties.
Best suited for
- Walls over 4–5 ft in height
- Walls supporting a driveway, structure, or pool deck
- Property-line walls needing an engineered, monolithic pour
- Waterfront lots requiring a stamped design
How it's built
A poured wall starts with excavation and a footing sized to the engineer's plan, then forms go up, rebar gets tied in a grid pattern, and concrete is poured in one continuous placement so the wall behaves as a single structural unit rather than stacked pieces. Cure time before backfilling is non-negotiable — rushing this step is how you get a wall that cracks under its first real load.
Taller poured walls, or any wall supporting a structure, typically require a stamped engineering plan and a permit before we can pull a crew onto the site. We handle that coordination as part of the project rather than leaving you to find an engineer separately.
Why it costs more — and when that's worth it
Forms, rebar, engineering, cure time, and often a permit add real cost compared to segmental block. What you get for it is a wall that can go taller, carry real structural load, and hold a tighter, more precise line — which matters when the wall is doing double duty as the edge of a driveway or the retaining structure under a pool deck.
For a straightforward 2–3 foot slope in a backyard, poured concrete is usually overkill and segmental block gets you the same result for less. We'll say so in the estimate rather than upselling a pour you don't need.
Waterfront and near-waterway lots in Martin County — along the St. Lucie River in Stuart and Palm City — are the projects most likely to trigger South Florida Water Management District or Martin County shoreline review in addition to standard permitting. We factor that review timeline into the schedule up front instead of surprising you with it mid-project.
Poured concrete FAQs
How much taller can a poured wall be compared to block?
There's no universal cap — it comes down to the engineer's design for your specific soil and load conditions. As a general pattern, poured walls are the more common choice once you're well past the 4–5 ft range where segmental block starts needing significant additional reinforcement.
Do all poured walls need a permit?
Most do, especially past a certain height or when the wall supports a structure. See our permit guide for St. Lucie County for specifics, and ask us to confirm for your exact project and municipality.
Can you match poured concrete to a finished look, or is it just gray?
Poured concrete can be finished, stamped, or veneered over — if the visual matters as much as the structure, ask about a stone veneer finish over the structural pour.
