A retaining wall looks simple — stack the blocks, hold back the dirt. But it's one of the most failure-prone structures in a yard. It has to resist the pressure of the soil behind it, the water that builds up after every Florida downpour, and any load sitting above it — a driveway, pool deck, or slope. Built without engineering, walls bulge, crack, lean, and slide.
The price of a retaining wall depends heavily on what it's holding back — height, length, soil type, and whether there's a driveway, pool, or slope pressing down above it. We engineer the wall for those real conditions, not a one-size-fits-all detail.

Most retaining walls don't fail from the weight of the soil — they fail from water. After a Florida downpour, water builds up behind the wall and pushes with enormous force (hydrostatic pressure). Proper drainage — weep holes, gravel backfill, and filter fabric — is engineered in, not optional.
A driveway, parked car, pool deck, or even a slope above the wall adds 'surcharge' load. A wall that's fine holding bare soil can fail when a driveway sits above it. The engineering has to account for what's actually up there.
Many counties require a permit and engineering once a wall passes a set height (often around 2–4 ft), but a surcharge load can require engineering at a lower height. We confirm your county’s threshold before you build.
'Just stacking blocks' from the store doesn't make a wall safe. Segmental retaining walls (SRW) rely on geogrid reinforcement buried in the soil at engineered spacing. Skip it and the wall bulges outward within a few seasons.
Sandy soil, a high water table, and heavy rain all change how a wall behaves. The footing and drainage are designed for your actual site conditions, not a textbook assumption.
When a retaining wall slides or collapses, it takes the driveway, patio, or landscaping above it with it — and repairs cost far more than the original engineering. Getting it right the first time protects everything nearby.
Block manufacturers publish generic capacity charts, but they don't know your soil, your wall height, your drainage, or the load sitting above. Only a site-specific PE design accounts for all of them together.
A PE-sealed package means a licensed Professional Engineer has calculated the soil pressures, verified the wall’s stability against sliding and overturning, and staked their license on every drawing. For a structure holding back tons of saturated Florida soil, that is the difference between a wall that lasts decades and one that fails after a season.
We don't reuse a generic detail. We design for your wall height, soil type, drainage, and any load above — so the wall is sized for what it's really holding back.
Hydrostatic water pressure is the #1 cause of retaining wall failure in Florida. We specify weep holes, gravel backfill, and filter fabric so water is relieved before it can push the wall over.
Overturning, sliding, and bearing are checked with calculations before a single block is laid — so the wall passes plan review and stands up in the field.

Tap True or False — then see the real answer. Most homeowners get at least one wrong.
"A retaining wall only has to hold back the weight of the soil behind it."
"Poor drainage is the leading cause of retaining wall failure."
"Stacking store-bought blocks is enough — no engineering needed for a segmental wall."
Now you know what most homeowners don’t — and why getting it right from the start matters.

Most Florida counties require a permit and PE engineering once a wall passes a set height (often around 2–4 feet), or any time there’s a load above it like a driveway or pool deck. We confirm your county’s exact threshold before you build.
Height, length, soil conditions, wall type (segmental block, poured concrete, or masonry), and whether there’s a surcharge load above it. Because it varies so much, we quote from $1,000 after seeing your specifics.
Yes — all three, including terraced/tiered walls on sloped lots and geogrid-reinforced SRW systems.
Water building up behind a wall (hydrostatic pressure) is the number-one cause of retaining wall failure in Florida. Every package includes an engineered drainage detail — weep holes, gravel backfill, and filter fabric.
