RV Concrete Pad Questions

I'm putting together a drawing package for the concrete pad in my upcoming garage and I would like some input.

Per the building drawing package the slab requirement is a 4" X 48'5" l X 20'3" with 12" X 12" footers. It also has a 1.5" X 1.5" sheeting edge. 2500 psi at 26 days. The slab is above grade.

I'm thinking about specifying a coach wt of 45,000 lbs and a max tire loading of 8,000 lbs to give the contractors and idea of what the point load will be.

Is that a good approach as opposed to simply specing the concrete type, thickness, and reinforcing?? After all they should be the experts.

Thanks again for all the valuable input on this project.

  • Labor is the biggest expense. Materials are cheap. PastorCharlie has the right idea. 6" is minimum I'd go....Dennis
  • When I poured my shop floor I poured 6" with three courses of 5/8 rebar around the edges and 4" with wire and 5/8 rebar crisscrossed in the floor.
  • Here in Yuma Az. There are many RV ports and the standard is a 6 inch slab. I personally have had two RV slabs pored and both were 6inches deep. 4 is to thin go with 6 you won't regret it
  • When I had my pad put in, I told the contractor the weight I needed to place on the pad and he built accordingly. He did a great job and no problems in the 3 years I've had the pad.
