Concrete garage floor

[Alexander6]

Six months ago I laid a concrete garage floor. It has only had light use but has started to crack and crumble. What did I do wrong and how can I fix it please?
Thanks. Alexander6

maybe laid too thin, too weak a mix, laid in frosty conditions, but if we could see a picture..........?

Thanks for your reply Noseall. Having read your reply I think I did make the mixture too weak and I definately laid it in frosty conditions. I think I'll have to dig it up and start again.
Thanks for your help, I appreciate it.

don't forget, drying out too fast can be a problem too.

concrete loves water and a longish drying time.

it simply hates frost though.

Thanks again Noseall - I'll be more careful when I lay the new floor, now you've told me the pitfalls.

Also when you laid id did you knock the air bubbles out in any way?? as these can also cause cracking

[Alexander6]

Thanks BigIan. I did tamp it down but I don't think I did a very good job. Thanks for the advice - I'll do better next time.
