concrete floor laid yesterday but it rained?

[Carameli]

basically as the builder finished laying the floor it started to drizzle but by the time they were going home there were moderate showers. He said it was really not a problem. But I was worried it was uncovered.
So called building control who said if the rain is not a huge down pour it will probably be fine but if I was worried today to call them out to look.

It looks ok, a few little marks. My only worry is that in one corner there are quite a few stones on the surface so I am worried the rain overnight possibly has washed the cement away from that area.
Don't want to call building control if its really minor and the screed will cover it afetr this anyway. But also don't want to just leave it if its going to make the floor weak. Waiting for the builder who will be here imminently to see what he thinks.

Gosh this is a ramble.

HAs anyone else got any experience of this. Should I just call building control even if it annoys the builder?

Wait til your builder has had a look at it and see what his response is - if you're not happy after that give BC a call.

Do you trust your builder to do a good job?

yes I do he is great but this has got me a bit worried

cement dries chemically so rain shouldn't be that much of a problem.

it the floor in of the extension and will have to have a screed over it to make it lovely and smooth anyway.
Builder has said its fine nothing to worry about and has just swept away the few stones. Think I will see what its like when it properly dried out in the sun.

will see how it goes I think.
