Wondering if any of you could help me evaluate bids on our Chicago-area residential driveway. We have it narrowed down to 2 contractors. They are about $1G apart, with the higher bid approx $8G to install a concrete driveway in our home.
The higher bidder proposes installing 1/2" rebar. The lower proposes using wire mesh combined with fiber added to the mix.
The higher bidder says wire mesh does nothing to reinforce the concrete, it only holds the concrete together once it starts to crack. The lower bidder says the rebar is overkill. Moreover he says it is hard to install properly for a 5" thick floating slab, and could actually cause problems.
Both propose using sealant. We do not use salt, and intend to do our best to keep salt off it for the first couple of winters.
Both have great references, and impress us with their professionalism.
I know nothing about concrete. All I know is that I don’t want to pay for a brand new concrete drive, and have it look like crap in a year or two.
It wouldn’t break our bank to go with the higher bid, but I hate to think I would be just pissing away a thousand dollars. This is such a frustrating thing, trying to make a decision about a product I really know nothing about.
