Rained hard right after concrete pouring
Rained hard right after concrete pouring
(OP)
Hi,
I am building a house, and yesterday the contractor poured concrete on the 2nd floor slab. Just about 5-10 minutes after the process was completed, it rained very hard for around 30 minutes. The areas were not covered on time, and some of slabs were soaked with water. I want to ask this:
According to the contractor, as long as the pouring is finished, it is okay if it rains because water will not penetrate the concrete as long as it doesn't happen during the process. Is this true? Because I saw water on top of the concrete, but there is no way to find out if it never penetrated the concrete.
So is it true that it is okay to rain right after (just 5 mins after pouring it rained) pouring, and that it won't penetrate the concrete?
Will this compromise the strength of the structure esp since this is a 2nd floor?
thanks

However, did this not ruin any smooth finish that was there prior to the rain? Or does that matter?

Smooth finish wiped off some of the surface. And when the men covered the area, they stepped on the concrete thus leaving footmarks. When the rain subsided, they removed the covered, and leveled the surface so the footmarks will be wiped away

Has the surface been damaged? and can you post a photo?

If the excess water is not worked into the concrete, probably no harm done to the concrete mass.
The flushed surface is a fault and that may be what the final dispute will be over.
