Wall systems
Drainage & Erosion Control
Not every water or erosion problem needs a new wall. French drains, swales, and regraded runoff paths solve a lot of Treasure Coast yard problems on their own — and they're the difference between a wall that lasts and one that doesn't.
What this covers
- Standalone French drain & swale installation
- Regrading to redirect runoff
- Drainage retrofits behind existing walls
- Erosion repair after storm events
When it's a drainage problem, not a wall problem
A slope that's washing out, a low spot that won't drain after every storm, or soil eroding along a fence line doesn't automatically mean you need a retaining wall. Often it means water doesn't have anywhere to go, and the fix is a French drain, a regraded swale, or a redirected downspout — all cheaper and less invasive than a wall.
We'll assess which situation you're actually in during the site visit and quote accordingly. If a wall genuinely is the right fix, we build it with the drainage system as part of the design from day one — see our drainage plan guide for what that includes.
Retrofitting drainage behind an existing wall
If you've got a wall — ours or someone else's — that's showing early signs of trouble (bulging, staining, water pooling at the base) but hasn't failed structurally yet, a drainage retrofit can sometimes extend its life without a full rebuild. We'll tell you honestly when a retrofit will work and when the wall is too far gone for anything short of replacement.
South Florida's June–September rainy season is when drainage problems show up hardest and fastest — see our guide on how much rain a wall and its drainage system can actually handle.
Lots backing up to canals and drainage rights-of-way — common in Port St. Lucie's grid of C-24 canal-fed waterways and in older Fort Pierce neighborhoods — have their own drainage rules on top of standard county code, since South Florida Water Management District manages canal-adjacent runoff. We check for that before quoting any wall or drainage work near a canal.
Drainage & erosion FAQs
How do I know if I need a wall or just better drainage?
If the slope itself is structurally stable and the problem is standing water or surface erosion, drainage work alone often solves it. If soil is actively sliding or a grade change needs to be held back permanently, that's a wall situation. We'll tell you which one you have.
Can you fix erosion without tearing out landscaping?
Often, yes — French drains and swale regrading can usually be routed around established landscaping with some planning during the site visit.
Do canal-adjacent lots need special permits for drainage work?
Sometimes, depending on proximity to the canal easement and the scope of work. We'll flag it during your estimate if your property is affected.
