RV & Boat Pads
RVs and boats are both common on South Lake County's larger lots, and the concrete they sit on shares a lot of the same technical spec — but they aren't the same job. An RV parks and stays for a season; a boat-and-trailer combination concentrates its weight differently, and often needs to be near a lake access route rather than tucked beside a house. This page covers both, together, because the underlying slab spec overlaps, and separately, because the loads and use patterns don't.
Figures above are published planning ranges, not a quote for your project. Size a pad to your specific rig with the RV & Boat Pad Calculator, then request a site-specific estimate.
Built for a load that parks and stays
A driveway is engineered around a rolling load — a car's weight crosses it and is gone. An RV pad has to hold a much heavier, stationary load in the same spot for weeks or months: jacks down, slide-outs out, axles bearing the full weight of a motorhome that isn't going anywhere. That's the reasoning behind building RV pads thicker (6 in is the number that shows up consistently across RV-focused concrete guides) and to a higher cure standard before anything heavy sits on them. See our RV Pad vs. Driveway guide for the full comparison, and the Concrete Driveways page if you're weighing whether to widen an existing driveway instead of pouring a separate pad.
A different load, and a lake-country lot
South Lake County sits inside a chain of lakes — Lake Louisa, Lake Minneola, Little Lake Harris among them — so boat and trailer storage is a routine request here, not a niche one. Most published cost and spec guides treat a boat pad as a copy of an RV pad, and the base numbers are close. But a boat sitting on a trailer concentrates weight on a few points — the tongue jack, the wheels, blocking under the hull — differently than a motorhome's distributed axle weight, and the pad gets wet far more often from wash-down and rain runoff off the hull. See Boat Pad vs. RV Pad for where the specs actually diverge.
Thickness, strength, and reinforcement
Both pad types start from the same technical baseline before diverging on load pattern and drainage detail.
| Spec | RV pad | Boat pad | Source |
|---|---|---|---|
| Thickness | 6 in (vs. 4 in driveway minimum) | 6 in typical | Consensus across RV/concrete contractor guides; Florida Building Code Ch. 19 sets the 4 in slab-on-ground floor |
| Strength | 4,000+ PSI | 4,000+ PSI | ACI 332 residential concrete guidance |
| Reinforcement | Rebar sized for stationary axle load | Rebar sized for trailer point loads | Industry consensus; wire mesh is not preferred for load-bearing slabs |
| Slope | ~1/8 in per foot toward drainage path | Same, plus wash-down runoff planning | cement.org mix-design and drainage guidance |
| Cure before load | 28 days (stationary heavy load) | 28 days (trailer + boat weight) | Standard concrete curing practice |
RV and boat pad questions
How much does a concrete RV pad cost?
$1,800–$7,200 is the published national range for a concrete RV pad (concreteslabcost.com), depending on pad size, thickness, and site prep — it isn't a Florida-specific or site-specific figure. Pad size (your motorhome's length and width), base condition, and mixer-truck access all move the real number. Use the RV & Boat Pad Calculator to size a pad to your rig, then request an estimate for a number specific to your lot.
How thick should a concrete pad be for an RV, and what PSI?
6 inches at 4,000+ PSI is the consensus repeated across RV-focused concrete guides — thicker and stronger than the 4-inch Florida Building Code minimum and 4,000 PSI standard used for an ordinary driveway slab. The extra thickness accounts for a large motorhome's concentrated axle and jack weight sitting in one spot for weeks or months, not rolling through like a car.
Do I need rebar in an RV concrete pad?
Yes — rebar sized for the load, not wire mesh, is the standard answer, same logic used for any heavy-load slab. Owners researching this on RV forums (Forest River Forums, iRV2) consistently land on rebar over mesh for anything meant to carry a parked motorhome's weight long-term.
How long do I have to wait before parking my RV or boat trailer on new concrete?
About 28 days. Light vehicle traffic is generally fine around 7 days, once concrete reaches roughly 70% of its design strength, but a stationary heavy load — a parked RV or a boat sitting on a trailer — should wait for full cure. Pulling a loaded rig onto a pad before then risks surface damage the concrete hasn't caught up to yet.
RV pad vs. driveway — what's the real difference?
A driveway carries a rolling load: weight that crosses the slab and is gone in seconds. An RV pad carries a concentrated load that parks and stays, sometimes for months at a time. That's why RV pads are typically built thicker (6 in vs. 4–5 in) and cured longer before use, even though the concrete mix itself isn't dramatically different.
How much does a concrete boat pad cost?
Most published cost guides don't treat boat pads as their own category — they fold the pricing into RV pad or general slab numbers ($6–$12 per sq ft installed is the published general slab range). That's a real gap in the available data: a boat-and-trailer load on jack stands and wheels isn't identical to a motorhome's distributed axle weight. Treat RV pad figures as a starting reference, not a boat-specific quote, and request a site-specific number.
What's actually different between a boat pad and an RV pad?
Both are typically built to a similar thickness and strength spec, but the load pattern differs — a boat trailer often concentrates weight on a few contact points (tongue jack, wheels, blocking) rather than spreading it the way a motorhome's axles do. South Lake County sits in lake country — Lake Louisa, Lake Minneola, Little Lake Harris — where boat-and-trailer storage is a routine ask that generic RV pad content doesn't address directly.
Do I need drainage or slope on a concrete boat pad?
Yes — the same roughly 1/8-inch-per-foot minimum slope used on driveways applies here, and arguably matters more. A boat pad gets wet routinely from wash-down, rain, and a dripping hull, so water needs somewhere to go instead of sitting against a trailer frame or tires.
