Urine on wall / on and possibly under screed

Dear forum community,

unfortunately, I noticed today that someone has urinated in a corner of my new-build apartment. This is not the first problem of this kind; for example, feces have also been left in a basement and a storage room of another buyer.

The urine is obviously on the wall, on the edge insulation strip, and a little (but not too much) on the screed. However, I fear that urine has also seeped under the screed and into the EPS insulation boards, as there is a small hole in the corner between the edge insulation strip and the wall, exactly where the urine ran down.

What problems could now arise for me? Unpleasant odors, mold, or something else? What should be done now?

Best regards

Incredible, I cannot assess the consequences, but I wonder who does something like that.... Unbelievable...

Extremely unpleasant odors. These are not masses of water that are left behind. At friends' place, the cats peed in a corner of the new building where no baseboard had been installed yet. So everything also ran down towards the screed. They went over it a few times with an odor remover. You can't smell anything anymore, and nothing is visible either. A porta-potty would do your construction site good.

There are two portable toilets available. Either one of them is deliberately an a**hole or one is too lazy to walk to the ground floor.

Deodorizer is all well and good – my concern is that the EPS insulation boards under the screed have soaked up liquid and will eventually start evaporating nicely. Or is that an exaggerated concern?

How many liters should the p....be fully soaked! Don't exaggerate.

Stupid question, but urine is the same as uric acid. Can it decompose anything if it doesn’t evaporate quickly? I’m thinking of plant leaves that have been peed on. They turn brown very quickly. It’s definitely nonsense, but I just wanted to put it out there...
