Concrete RV pad in Austin: size it from the rig
Start with a tape measure, not a chart. The pad has to hold the rig bumper to bumper, including the hitch or tongue, with room to walk around both ends and enough width to open the slide-outs and the door over concrete. In Austin, people search “concrete RV pad” because a bare “RV pad” search turns up RV lots for rent.
| Rig | Pad to start from | Area | Concrete at 6 in (net) |
|---|---|---|---|
| Boat or utility trailer | 10x25 | 250 sq ft | 4.63 cu yd |
| Travel trailer or Class C | 12x40 | 480 sq ft | 8.89 cu yd |
| Fifth wheel | 14x45 | 630 sq ft | 11.67 cu yd |
| Class A coach | 14x50 | 700 sq ft | 12.96 cu yd |

Starting sizes, not rules: measure your rig and add clearance. Concrete volume computed at 6 inches before waste; the calculator handles other sizes.
Thickness and steel for an RV pad
An RV's weight lands on a few tires and stabilizer jacks, which press small areas hard. HomeBlue's Austin guide puts residential slabs at 4 to 6 inches; an RV pad sits at the top of that range or above it, with rebar on chairs and a compacted base. On Houston Black clay, which the USDA describes as very slowly permeable and cracking up to 4 inches wide when dry, the base and drainage matter as much as the concrete.
Joints on a long pad
A 40 foot pad needs joints. NRMCA's guidance caps spacing at 24 to 36 times the slab thickness, 15 feet at most, with panels no longer than 1.5 times their width, so a 12 foot wide pad is cut into panels about 12 to 15 feet long.

Both sources price a typical 4 to 6 inch slab; a 6 inch pad with heavier rebar lands toward or above the top. Removing turf or an old slab ($1.10 to $1.70 per sq ft, HomeBlue Austin) is extra.
Odd shapes, like a pad that bends around a corner of the house, can be split into rectangles in the slab calculator.
Curb cuts, impervious cover and HOAs
The pad itself is private flatwork, exempt from a City building permit. Getting the rig to it is where the rules start. Any new or widened driveway approach across the curb and sidewalk needs the City's Driveway/Sidewalk permit, and the City says a right-of-way contractor's license is required to do that work. The pad also counts toward impervious cover, and HOAs often have their own rules about where an RV may be kept.
- Rig length including the hitch, and its width with slides out
- Where it will back in from, and whether that needs a new curb cut
- Your lot's zoning and how much impervious cover is left
- HOA rules on RV and boat parking
- Hookups (power, water, dump) that run under the pad
