Our driveway is about 20 years old, and has been cracking for several years now. It even looks like it is sinking in some areas. From what I see, the concrete is only 3" thick, and there are no steel rods below.
I mention steel rods because a company who came out to give me a quote said that it needs to be at least 6" deep and have steel rods criss-crossing below.
What do I need to know before I accept one of these quotes (besides the obvious: references)? I am trying to be an informed customer so I will know what I am going into.
Would appreciate any advice on this topic. BTW, it is a regular 2 car garage, so not a wrap around drive, just a straight drive up from the street to the garage.
