Hello!
The heavy rain over the past few days has caused water damage at my construction site.
The recently installed screed (anhydrite) on an area of 3x4 meters (10x13 feet) is underwater or completely saturated 😡
Question for the experts: Can the screed withstand this? Can it stay in place after drying, and what is the most cost-effective way to dry the surface?

It is quite a feat to drill into the screed without damaging the insulation. I also believe that with this type of screed, it needs to be replaced.

But it is possible, it just requires a skilled company. In my neighborhood, the same approach was used. Their screed was also flooded after water damage. They carefully drilled into the floor and blew warm air inside.

Whether this is the ideal solution, I cannot say.

We also followed the advice of our architect and chose anhydrite screed. Unfortunately, about 3 months ago, there was a water intrusion, and the floor was completely flooded. The drawback is that anhydrite screed is very sensitive to moisture. Although the drying time is relatively short, the disadvantage outweighs the benefits.

Now we have had it replaced with cement screed, which is more durable.
