Will the base joint withstand standing water after heavy rain?
Due to the location of our house, it is possible that the base joint (construction joint between the structural slab and the floor buildup) will be underwater for about 2 hours during extreme rain (maybe once every 5 years) with water reaching approximately 7 cm (3 inches) above the joint. The water level cannot rise higher because it will then drain over the street crown. Unfortunately, we are not allowed to raise the house.
Therefore, our questions:
1. Will this construction joint hold up against this standing water (about 7 cm (3 inches) above the joint for approximately 2-3 hours)?
2. And what about the waterproofing of the floor-to-ceiling doors/windows, will they also withstand this?
Our house is a standard model from Town & Country, without a basement and simply plastered on the outside, with mineral-based waterproof slurry at the base area.
Thank you very much for your help!!

If the seal was only designed to protect against 'ground moisture,' wouldn't it fail immediately and not even hold back standing water for at least an hour or so? The water height above the joint would only be about 7cm (3 inches).Most likely, yes. Rising damp or moisture in general is quite different from actual water.
