Hello dear forum members, I hope someone can help us 😕
About 3-4 weeks ago, we excavated around our basement walls because we want to apply a new bitumen and waterproofing layer.
But the walls just won’t dry... 🙁 According to the measuring device, some spots still show OL, meaning over 40% moisture?! And the current humidity in the air isn’t helping either.. The house was basically flooded because there was no drainage system for years.. Even the plaster inside has started to crumble in some places or there are water stains..
Now my question is: how can we get the walls dry ASAP? We already had to postpone the exterior insulation (which also needs to be done this year for the KfW subsidy)
Would a dehumidifier, which can be rented, help? Or do these only dry the air in a room? The bitumen and waterproofing layer (which is a compound that is troweled on) can only be applied once the walls are dry all over, right?! I hope someone can help us :o

Hi,
In our newly built house, we unfortunately already have a damp wall in the basement. I hope this is not a direct construction defect and that we won’t end up with a major renovation right away. For now, we want to test the situation with a dehumidifier to see if it might just be residual moisture from the construction. I hope this is the right place to ask about dehumidifiers. We are certain we want to use a dehumidifier, but we don’t know which type to choose. I did some research online and found there are different types like dehumidifiers, construction dryers, and adsorption dryers. Basically, we want to buy a good dehumidifier because we think it’s always useful to have one. Can someone recommend which dehumidifier we should get? Thanks in advance.

How long has the basement been standing?
If the basement has been there for a while and only one wall is damp, it usually rules out residual moisture.
For drying our construction, we rented a construction dryer. Normally, you don’t need one after that. It served us well for 2 weeks and dried everything thoroughly.
