I'm a good read of folks and this guy knows concrete.... he's been doing it for 23 years. This contractor knows concrete like I know turf....it was fun to watch him look and think.
I have one more coming out Friday.....and I know he's not as experienced.
I guess this is what you get from new construction even when family does it for you!
His cash price is 15% less.!

I only give 5%
In a way it was fun to be on the other side where someone is giving me the estimate. I'm too often giving the estimate and watching the reaction. Talk about stone cold! That was me. But is was really fun and gives a different perspective.
The expansion joints...he pointed it out. My drive is the only one in view that does not have three.....someone must know something.
He also verified my suspicion in that he does not believe it's even 4" thick (although not certain, he suspects). In addition he verified what my brother, owner of a mudjacking company, said in that it's a weak mix. Without even saying anything he picked up a piece of the spalling concrete and said that it's a "patio mix" or "6 bag". His estimate includes fiber in the 6.5 bag mix.
Same here with new construction concrete...they pour in any weather, on top of anything, including mud and snow. The irony is that the builder, my father in law, had his most recent driveway laid over 4" of compacted 3/4 minus crushed limestone....after 3 months....re-bar and mesh included. Makes you wonder
I have considered paving it....yet the plan is to move in 2-3 years and I'd be the only one in the neighborhood with pavers.
