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

It was still too soft for heavy rain, so now it is bumpy. The fine material was washed away, but the pebbles remained. However, the binder is cement. That did not wash out. Definitely not. Just wait and see how it looks once it has hardened. Whether you need to add more on top, or if the screed specialist can level it out. There’s nothing you can do today anyway.

I’m just concerned about the words of the foundation slab construction manager. An hour before the heavy rain, he said a little rain would be a great form of curing, but rain like yesterday would be really bad.....So why doesn’t the respected foundation slab manager protect his work from such exposure, for example with tarps?
Generally, you can’t do anything yourself, or are you the site manager? Let the professionals handle it ... that’s what warranties are for.
Otherwise, a well-meaning piece of advice: relax, or you’ll come out of your house construction 20 years older. These are just minor issues now.

UPDATE:
The surface doesn’t look too bad; it’s not exactly attractive, but it’s acceptable.
However, what was visible after removing the formwork is less pleasing to me. As a layperson, I can’t judge if this is still okay, especially at the corner, but the site manager from the foundation crew said it was completely fine (which is understandable, of course).
I would really appreciate honest opinions on the following pictures:
