Concrete pad

[cold_iron]

I live in a RV community, 300 lots all class A's . Everyone has a concrete slab's. Mine is 55 long by 25 wide. They all have 12 + inch footers with rebar. Most have wire mesh and fiber glass. Spend a bit more and it will keep you happy for a long time.

We just finished pouring 40 yards today. It is an RV garage floor, so that includes the front and rear aprons. I used 4000psi, fiberglass strand mix, with welded wire over 6 mil poly, and the slab is 6" minumum, with 7" in some areas.

I poured a similar slab for an RV pad alongside the house, about 10 years ago. Not a single crack in it, and I have used my jacks both with and without blocks, many times.

If the base over which the concrete is poured, is rock solid, there should be no problem with cracking, even with less than 6".

Bill Adams offers the best advice. I consulted a concrete company and they poured my 16' by 55' pad 5 years ago with correct drainage and rebar and fiberglass reienforcement and no cracks. 35,000 lbs MH.

CaptBill, This is just about what I have on my 40 x 14 pad here at our house. I also have about 50 feet or more of driveway and they used the same type of cement. 5 years now no cracks. Can't say as much for the driveway in front of my garage where we park the car. The slab is cracked all the way through. OF course it didn't help I expect when I put my motorhome on that part of the driveway. I have a Y type driveway with the MH on one side and the garage & car on the other.

The RV pad was done after the driveway.
