Severe weather warning tomorrow, red level for our construction area!

Hello everyone,

a severe weather warning has been issued for our construction site tomorrow from 2 pm to 5 am the following morning. It is level red with warnings of heavy rain, hail, and hurricane-force gusts.

At the moment, our foundation slab is prepared for the concrete pouring planned for Monday.

Current status:

- 18 cm perimeter insulation installed
- foil on top of that
- spacers and one layer of reinforcement steel

Can I leave everything as it is shown in the picture and not worry, or should I secure something or do anything else?

Could hail cause serious damage to the foil or the perimeter insulation?



Thanks in advance,

greetz Jörg

I may not be able to take away your fear, but I want to ask you not to exaggerate.

In your area (if it is Germany) there is (as in about 30% of the federal territory) an advance warning before local severe thunderstorms. So it can affect you, but it does not have to.

But now to what bothers me. Where did you get the information about a hurricane? That would be Beaufort 12. There is currently no such report. The highest reports are of severe storm (so Bft 9).

Steel will at least not fly away there, unless somewhere wind can get under a supporting layer/tarp.

Who is the builder? Who is the construction manager? Talk to each other.

Well, I am the client, the site manager has not yet seen the current status, he wanted to come on Monday... Anyway, nothing will probably happen, I just wanted to know if something should still be secured.

If concrete work is scheduled for Monday, the construction manager will already know how far along things are now.

I would be worried about tarpaulin-covered construction fences or styrofoam packages. Or covering tarps and things like that. Or if the wind can get underneath somewhere. I think the hail can’t do much damage. It cushions rather than really breaking through.

I would be more afraid that the ramp on which the house is supposed to stand will wash away :(

How would you secure something now? I mean, with what means? All the shops are closed, do you have 150sqm of tarp at home :) The steel is already inside and twisted together. Lifting a mat like that by the wind is pretty unlikely. At most, a construction fence would tip over if there’s a sign on it or the Porta potty :)
