Concrete Patio Cracks After 5 Months
We had a large concrete patio laid in November 2008. Over the winter, it developed numerous cracks. The contractor insists it was poured correctly and that the cracks were caused by the frost from a cold winter. Is this possible? We are so disappointed.

Could be the complete truth. My thoughts here is what was done in the prep for crushed stone under the concrete. My other thought here is how could was it after it was poured and how much time went by before it froze? Personally I cover ALL ground level pours if frost is or will be present. I give it a week and a half before I uncover. Also I do a gradual uncover to let the new concrete adjust to the quicker temp change. Use plastic and straw and concrete warming blankets to cover and adjust If you could give me some more details I may tell you why it was more prone to crack. Its been a hard winter for many people and its played havoc on old concrete and New concrete is very susceptible. Signed 21 Boat If I Helped To Answer Your Question Please Rate My Answer |

21Boat - So you think we are just screwed? There is no way for me to "prove" they did anything wrong. The base passed city inspections, etc. It's just such a joke that we paid $5,000 for a patio full of cracks. Didn't even get to enjoy it for one summer. Any suggestions?

I HATE saying this but you are probably screwed. Even though the base passed inspection doesn't mean it was correct. Concrete slabs are so under inspected in residential The only way you would get close to a blame here is the temperature record of the days following the actual pour. If that dipped to or below frost then you have a case to present. Concrete takes a week or so to cure enough to reach 65 to 70%+ at 70 degrees and up. When its poured at 50 or 40 degrees this exponentially changes the curing time which in turn means longer cover for the concrete not to move in less strength days. Other wise the percentage of a chance for it to crack greatly increases. |
