Have you cracked a driveway?

Yahoo Message Number: 19149
We usually park at a friends driveway while in the SF area BUT since we bought our Magna we are afraid of cracking their driveway. The house is at least 20 years old and I am sure it was never intended to park our 36K pound motorhome on. Any thoughts on this.

I have cracked my drive way in several places over the past year. I have an 05 Intrigue and it weighs approx 38000 pounds. Unless your friends purposefully poured their driveway thick with a high psi concrete, I would not park on it. I had my motor home pad poured approx 6 inches thick with 8 inch thickness around the edge with 3500psi concrete and I have not had a crack yet (knock on wood).

We just had a high PSI rated concrete pour to park our coach by our house. Added about 100 feet of driveway which was 6 inches thick with rebar enforcement. Works well.

My family's been in the concrete business for over 50 years. 20 Cement Trucks over 40,000lbs each park on a 4" slab every day and no cracks. Parking on a slab and rolling on a slab at 65 mph are two different things. Parking does not cause daily pounding on the slab. 3500psi with wire or rebar in the slab is extremely important. Also, the foundation underneath the slab is the most important. You should have packed limestone on a hard surface before you pour your slab. Remember, the earth moves and the ground will settle under the slab if not packed well. If the slab is used for parking only, 8" edges are irrelevent. The only purpose for a thicker edge is if you will have a load bearing wall on the edge.

You make some very valid points, however if the driveway was poured by a builder he was not interested in the longevity of the driveway. So it is probably safe to say the drive way is probably not 3500 psi and it may or may not have wire/rebar and I would bet it does not have packed limestone. Most builders are interested in saving money. My driveway that was poured with my house has cracked in multiple places from parking my motorhome on it in the past year.
