An RV Pad in Arco That Doesn't Crack Under 30,000 Pounds Looks Like This

Parking a Class A motorhome or loaded fifth-wheel on a properly built concrete pad in Arco means the surface stays flat, the jacks find solid resistance, and the slab shows no cracking or settlement after five winters — because the engineering behind it accounts for the actual point loads that RV stabilizer jacks apply, not just the gross vehicle weight spread across the entire pad. Owens Quality Concrete builds RV pads to the load specifications your vehicle actually imposes, which means thicker concrete, closer-spaced reinforcement, and a base depth calibrated for both vehicle weight and Arco's freeze-thaw environment.

Arco sits at over 5,300 feet in the high desert of Butte County, where frost penetration can reach 36 inches and summer temperatures push concrete surface temperatures above 120°F. That thermal range causes more expansion and contraction stress in a slab than most lower-elevation sites in Idaho, and it is why RV pads poured with residential driveway specs — adequate for a pickup truck but not for a 30,000-pound coach — develop diagonal cracks at the corners and depressions under the tire contact zones within the first two seasons. After replacement by Owens Quality Concrete, the pad surface remains flat and crack-free under the same vehicle and the same conditions.

The process begins with a site survey that confirms pad dimensions, access geometry for your specific vehicle's turning radius, slope direction for drainage, and proximity to utilities that may constrain excavation depth. Old pads that have cracked, settled, or were undersized are demolished and removed entirely before excavation begins — pouring over a failed slab transfers those existing cracks into the new surface within one heating season. Excavation depth in Arco is set to reach below the frost penetration depth for Butte County and accommodate a minimum six-inch compacted gravel base, which means total excavation typically runs 12 to 16 inches for a properly built RV pad at this elevation.

The compacted gravel base is installed in two lifts, mechanically compacted to reduce settling under point loads from jacks and tire contact. Rebar is placed on a grid matched to the expected point loads — typically No. 4 bar on 12-inch centers for Class A motorhomes — elevated to the mid-depth position in the slab rather than resting on the base. Concrete thickness runs a minimum of five inches for lighter trailers and six inches for larger coaches. Control joints are cut to a depth one-quarter of the slab thickness within 24 hours of the pour, directing shrinkage cracking to planned locations away from the tire contact zones and jack positions.

RV pad projects in Arco follow a defined sequence that connects each phase to the performance outcome you get at the end. Here is what that process looks like from first contact through final cure:

• Site assessment to confirm vehicle dimensions, turning radius clearance, drainage direction, and utility locations before any demolition or excavation begins
• Full removal of any existing failed concrete so the new base is installed on undisturbed or recompacted native soil rather than over a compromised substrate
• Excavation to Arco's frost penetration depth plus base thickness, preventing the ground movement that cracks pads poured above the freeze line
• Gravel base compacted in lifts with mechanical equipment, creating a load-distribution layer that keeps point loads from jack pads and tires from punching through to native soil
• Rebar grid at the correct mid-slab elevation with control joints cut at planned intervals — so any future shrinkage cracking is invisible and structural integrity is maintained

The pad is kept free of vehicle traffic for a minimum of seven days after the pour, allowing the concrete to reach the compressive strength the design depends on before it carries any load.
