A clean, level parking pad is more than curb appeal—it protects your RV and your property.
In Eagle and the greater Treasure Valley, an RV pad needs to do two jobs at once: carry substantial loads and survive freeze/thaw cycles. If the base prep, drainage, joints, and concrete mix aren’t aligned with local conditions, pads can settle, crack, and hold water—exactly what you don’t want next to your driveway or backyard. This guide breaks down what matters most so you can plan a pad that stays strong, drains right, and looks sharp for years.
What makes an RV pad “built right” in Eagle?
RV pads fail for predictable reasons—almost always tied to the ground beneath them or water moving where it shouldn’t. A high-quality RV pad is a system: subgrade + compacted base + concrete slab + joints + drainage details. When those pieces work together, you get a pad that resists rutting, rocking, pooling, and premature cracking.
Local note for Eagle: Building practices must account for frost conditions. Eagle’s municipal code amends the IBC to reference a 24-inch frost depth (unless a foundation investigation recommends otherwise). While an RV pad is not the same as a house foundation, this is a clear reminder that frost movement is real here and site-specific details matter. (codelibrary.amlegal.com)
Key design choices that affect durability
1) Thickness and reinforcement (built for real loads)
RVs concentrate weight under tires and stabilizers. Thickness depends on RV class, soil quality, and base depth. Many homeowners assume “more concrete” fixes everything—when the real secret is a properly compacted base, correct joint spacing, and a mix designed for freeze/thaw exposure.
2) Drainage and slope (the quiet MVP)
Standing water is a top contributor to surface scaling and freeze-related damage. A well-planned RV pad uses subtle slope to move water away from structures, walkways, and garage slabs, and keeps downspouts/sprinklers from soaking the edges.
3) Freeze/thaw performance (Idaho reality)
In climates that freeze, concrete durability depends heavily on the mix design and curing. Industry guidance commonly defaults to 7 days of curing when temperatures are above 10°C (50°F), supporting strength and long-term durability. (fhwa.dot.gov)
Quick comparison table: common RV pad approaches
| Approach | Best for | Pros | Watch-outs in Eagle |
|---|---|---|---|
| Concrete RV pad | Long-term parking, clean access, low maintenance | Strong, clean look, easy to sweep, handles jacks well | Needs correct base prep + joints + curing to resist freeze/thaw and settlement |
| Pavers (reinforced base) | Decorative layouts, repairable surfaces | Individual units can be reset; strong visual curb appeal | Edge restraint + base compaction are critical; poor drainage can lead to shifting |
| Gravel pad | Budget-focused, temporary solution | Fast install, flexible footprint | Can rut, migrate, and require frequent regrading—especially with heavier rigs |
Did you know?
Frost depth guidance matters locally: Eagle’s code references a 24-inch frost depth unless a foundation investigation suggests another depth. That’s a strong indicator that soil and frost movement should be respected in exterior concrete planning. (codelibrary.amlegal.com)
Rebar needs proper cover: ACI guidance commonly calls for 3 inches of concrete cover when concrete is cast against and permanently exposed to earth, and more cover when exposed to weather/earth depending on bar size. Correct cover helps protect steel from corrosion and surface staining. (irebar.com)
Curing isn’t optional: Default curing time is often referenced as 7 days (at temperatures above 10°C/50°F) to support durability—not just early strength. (fhwa.dot.gov)
Step-by-step: how a quality concrete RV pad gets built
Step 1: Plan the footprint, access, and setbacks
Start with how you actually use the RV: door swing, slide-outs, hookup location, turning radius, and whether you want room for trash bins or a small patio zone beside it. If you’re tying into an existing driveway, plan the connection so water doesn’t funnel toward the garage or collect along the seam.
Step 2: Evaluate subgrade and bring in a proper base
The subgrade (native soil) must be shaped and compacted. Then a granular base is installed in lifts and compacted to reduce settlement. This is one of the biggest differences between a pad that stays level and one that starts “dishing” after a season or two.
Step 3: Set forms and drainage (before concrete shows up)
A slight slope is planned so water leaves the pad instead of sitting on it. Downspouts, sprinkler heads, and nearby landscaping should be considered so runoff doesn’t saturate the edges—edge saturation is a common cause of settlement and cracking.
Step 4: Reinforcement placement with correct cover
If reinforcement is used, it needs to be positioned correctly (not sitting on the ground). Concrete cover requirements vary by exposure—concrete cast against earth is commonly referenced at 3 inches of cover, and weather-exposed elements require more cover depending on bar size. (irebar.com)
Step 5: Pour, finish, joint, and cure (the “no shortcuts” phase)
Control joints are placed to encourage cracking to occur neatly where planned rather than randomly across the slab. After finishing, curing begins. A 7-day curing period is a common default reference when temperatures are above 10°C (50°F). (fhwa.dot.gov)
Where homeowners get tripped up (and how to avoid it)
“It’s just a slab.”
For RVs, the base, compaction, and drainage are as important as the concrete itself.
Ignoring water sources
Sprinklers hitting the slab edge, downspouts dumping next to the pad, or low spots that pond can shorten lifespan.
Skipping curing protection
Curing helps concrete gain strength and reduces surface issues; a 7-day default is widely referenced for standard conditions. (fhwa.dot.gov)
A local Eagle, Idaho angle: what to prioritize for Treasure Valley properties
Eagle homes often have beautifully finished outdoor spaces—patios, walkways, retaining walls, and fire features. A well-designed RV pad should fit that same standard: clean edges, consistent grading, and finishes that complement your driveway and backyard.
Because Eagle’s code references a 24-inch frost depth for frost protection (unless a foundation investigation recommends another depth), it’s wise to treat site conditions seriously—especially if your pad will be near irrigated landscaping, has poor natural drainage, or sits on variable soils.

FAQ: RV pads in Eagle, ID
How thick should a concrete RV pad be?
It depends on RV weight, soil conditions, and base prep. Thickness is only one part of performance—compacted base, proper jointing, and drainage are often the deciding factors for long-term results.
Will my RV pad crack?
Concrete can crack—control joints help “tell” it where to crack so it stays neat and predictable. Proper base compaction and curing also reduce random cracking and surface issues.
How long does concrete need to cure?
Curing time depends on weather and specifications, but common guidance references a 7-day curing period when temperatures are above 10°C (50°F). (fhwa.dot.gov)
Do I need rebar in an RV pad?
Not always, but reinforcement can help manage cracking and support edges and transitions. If reinforcement is used, correct placement and concrete cover are essential for durability—especially for exterior exposure. (irebar.com)
How does Eagle’s frost depth affect an RV pad?
Eagle’s code references a 24-inch frost depth for frost protection (unless a foundation investigation recommends another depth). While an RV pad isn’t a house foundation, this highlights the importance of frost-aware planning: drainage, base prep, and minimizing saturated soil at edges. (codelibrary.amlegal.com)
Glossary (helpful terms for planning an RV pad)
Base (aggregate base): Compacted crushed rock placed under the slab to support loads and improve drainage.
Control joint: A planned joint cut or formed into concrete to help cracking occur in straight, predictable lines.
Curing: Protecting concrete from drying out too quickly so cement can hydrate and the slab gains strength and durability (often referenced as ~7 days under typical conditions). (fhwa.dot.gov)
Subgrade: The native soil beneath the base and slab. It must be properly shaped and compacted.
Concrete cover: The thickness of concrete protecting reinforcement steel from moisture and corrosion; requirements change based on exposure (earth/weather). (irebar.com)
