Hello everyone,
A severe weather warning has been issued for our building site tomorrow from 2 p.m. to 5 a.m. the following day. It is a red alert with warnings of heavy rain, hail, and hurricane-force winds.
At the moment, our base slab is prepared for the concrete pour scheduled on Monday.
Current status:
- 18 cm (7 inches) of perimeter insulation installed
- plastic sheeting on top
- spacers and one layer of reinforcement steel
Can I leave everything as it is shown in the picture without worry, or should I secure anything or take other precautions?
Could hail cause serious damage to the plastic sheeting or the perimeter insulation?
Thanks in advance,
greetz Jörg

Your wish is my command, but I have learned that concrete does not cure properly if the binder is washed out, which can be identified by the cleanly washed-out gravel. But of course, I would prefer everything to be correct.
I still see a difference between heavy thunderstorm rain and heavy rain. In the pictures, you can see the craters the drops leave on the water surface when they hit. They were large and very fast!

Therefore, I consider the heavy thunderstorm rain harmless. The reaction process has started. The concrete has not turned to mush or run apart. The water does not harm the reaction. It is very hygroscopic and will absorb the moisture it needs for the reaction. The rest will dry out.

Just because there are a few loose gravel pieces doesn't mean the binder in the slab is completely gone.
However, you can only tell for sure tomorrow or by the specialists on site.
The photos are not very conclusive.
The question I would rather ask is what type of curing method is planned for the concrete.
Covering? Moistening? Spraying?

I’m just a bit concerned about what the foundation construction manager said. About an hour before the heavy rain, he mentioned that a little rain would actually be a great curing treatment, but rain like yesterday’s would be really bad... As it happened, we got the heavy rain just like yesterday.
