Question DetailsAsked on 5/31/2012

jwb
I just had a new concrete driveway poored. The next morning several cracks have shown up in the concrete.

My contractor says that this is normal and will not effect the integrity of the concrete. My contractor had a representative from the material supplier come out and take a look, he also said that this was normal. I looked at my neighbors 1 yr old driveway and there is not a single crack in it. I elected to hold the final payment until I get a satisfactory answer. Please advise me if this is normal.

There are 2 things for certain about concrete. It will crack and no one will steal it.

Seriously, The cement should not have cracked this soon. Cracks are caused when the concrete shrinks. This is often controlled by expansion joints. These joints are placed uniformly in the cement to control the cracking. If there is any cracking it should be in these grooves. These cracks should then be filled with a sealant. The cracks could be indications that the cement was not properly mixed, the forms were inadequately braced, or the ground under the cement was not properly packed or all the above.

I don't know what part of the country you live but if you have cold winters, the freeze thaw cycle will only cause the cracks to worsen. All cracks in the driveway need to be sealed with proper sealant to prevent further damage.
