The pad also has to sit right in the yard: level enough to park on, pitched enough to shed water, and reachable by the vehicle without tearing up the lawn. On the clay soils around Winston-Salem the base matters as much as the slab, because a heavy vehicle parked on a pad over poorly compacted clay is exactly the load that finds a weak base.
| What changes | Effect on your price |
|---|---|
| Square footage | The single biggest driver. Work is priced per square foot, so measure before you call. |
| Slab thickness | 4 inches is standard. Going to 5 or 6 inches for heavy vehicles adds material across the whole pour. |
| Reinforcement, wire or fiber | Adds roughly 10 to 15 percent over a plain pour. Worth it anywhere a vehicle or a heavy load will sit. |
| Weight of the vehicle | A loaded RV or a boat on a trailer is a heavy, concentrated, long-parked load. That is why these pads are poured thicker and reinforced harder than a car drive. |
| Base condition | The wildcard. Sound compacted gravel can lower the price. A failed base that has to be rebuilt raises it more than anything else on this list. |
| Grading and drainage | Priced separately from the concrete. On a sloped or poorly draining site it can be a large share of the job. |
| Reaching the parking spot | The vehicle has to get to the pad without tearing up the yard, and the truck has to reach it to pour. Access moves the price. |
We start from what is parking on it, an RV, a boat and trailer, or both, so the footprint, thickness and steel are matched to the real weight and length rather than a standard slab.
The spot is cut to grade and a compacted base is built to carry a heavy vehicle that sits in one place for months, which is the load that exposes a weak base on clay.
Forms are set level enough to park on but with enough fall to drain, and a rebar grid is placed and supported so the slab carries the concentrated weight.
The pad is poured to the heavier thickness, finished with a broom texture for grip, and jointed so any shrinkage cracking follows the joints.
Concrete reaches full strength at about 28 days, so a heavy RV or loaded trailer should stay off a new pad until it has cured, or the weight can crack a slab poured specifically to hold it.
Call or text with the rough size and what is there now. A photo of the space answers half the questions before anyone drives out.
Someone walks the job, measures it, checks access and drainage, and leaves you a written number. Free, and there is no pressure attached to it.
Once you approve the price the work gets scheduled around the weather window. You get a start date and a realistic finish date, not a vague week.
Almost every regret in this category is about building the pad too small or too thin for what eventually parks on it.
A pad for a boat on a trailer and a pad for a large motorhome are not the same slab. Anything carrying a heavy rig starts meaningfully thicker than a car driveway, with rebar rather than mesh, and thickened further where stabiliser jacks land. Jack pads concentrate enormous load into a few square inches, and a slab that handles the rolling weight fine can still crack under the jacks. Tell your contractor where the jacks come down.
This is the most common regret and it is the cheapest to avoid. Extra length costs a modest amount of concrete at construction and is effectively impossible to add neatly later, since the extension will not match. Allow for the vehicle plus opening doors, plus slide outs where fitted, plus room to walk around it, plus any future longer vehicle.
The pad drains so water does not pool under a vehicle that sits for months, since standing water under a rig is bad for the vehicle and for the slab. If there is any prospect of wanting power, water or a sewer connection, sleeve them under the slab during construction. Coring a finished pad later costs many times more than the sleeve.
Mostly residential, with a straightforward commercial version.
Home RV parking, boat and trailer storage, and covered vehicle pads. The value case is straightforward: it keeps a heavy vehicle off grass that it would otherwise rut and off a driveway it would otherwise block. Worth checking any local restrictions or covenants on where a recreational vehicle can be stored before designing the pad.
Storage yards, dealerships and marinas. These are effectively heavy duty car parks and follow the same rules: thickness by traffic zone, engineered where loads warrant it, deliberate drainage, and jointing planned around the traffic pattern. Turning radii and manoeuvring space usually govern the layout more than the parking bays themselves.
An RV or boat pad is a driveway built for a much heavier vehicle that sits in one spot for months at a time. The two things that change are the thickness and the fact that the load is static and concentrated rather than rolling and distributed.
Design starts from the loaded weight of the vehicle, its length, and where the axles and stabiliser jacks actually land. A large motorhome loaded for travel weighs far more than people estimate, and stabiliser jacks concentrate that weight onto four very small points.
A pad the vehicle cannot comfortably reach is a pad that will not get used. Turning radius, overhead clearance for branches and lines, and the approach from the street all get checked at layout, because they are free to fix now and impossible later.
Deeper excavation and a thicker compacted aggregate base than a car driveway. Soft spots are dug out and replaced rather than compacted in place, because a soft spot under a static multi tonne load will find itself.
Rebar on a grid, chaired at the correct depth. Edges thickened where the wheels track on and off, because slab edges are where heavy vehicles cause damage first.
Placed, consolidated thoroughly and broom finished. Slope is set so water drains off the pad rather than pooling under a vehicle that will sit there for months.
Control joints cut the same day in roughly square panels. On a long narrow pad the joint spacing follows the width so panels do not become long rectangles, which crack across the middle.
Electrical, water and any sewer connection are far cheaper to sleeve under the pad now than to add afterward. If there is any chance of wanting hookups later, the sleeves go in during construction.
This is the step that matters most and gets rushed most. Foot traffic at 24 to 48 hours, light vehicles at seven days, but the full loaded weight of an RV or a loaded trailer waits for 28 days. Parking a heavy rig on a slab at ten days is a very effective way to crack a correctly built pad.
Standard pour weather rules. The practical scheduling issue is the 28 day wait before use, which needs planning around travel season rather than around the pour date.
RV & Boat Pads across Winston-Salem, Kernersville, Walkertown, Rural Hall, Union Cross, Pfafftown, Clemmons, Lewisville, Stanleyville, Belews Creek, King, Germanton, Oak Ridge, Colfax, Summerfield, Stokesdale, Wallburg, Midway and Welcome.
Most jobs touch more than one of these. If you are already pricing rv & boat pads, it is usually worth pricing anything else you have been putting off in the same visit, because the mobilisation is already paid for.
