Hello everyone,
I have recently bought a new house. Unfortunately, we have experienced water damage for the second time. The builder’s analysis showed that it is caused by hydrostatic pressure. He is now sealing the exterior of the house to prevent this.
We have a cavity wall construction. The builder is currently applying PCI Bareseal directly onto the brickwork (photos).
Is this sufficient?
Thank you

Again... be sure to get an expert involved before any more work is done here.

WilderSueden20 Apr 2023 11:52You are misunderstanding something. By drainage strips, I don’t mean the drainage pipes, but the gravel strip. With proper planning, water should not stand permanently against a house without a slab foundation, which is why I asked about the site’s terrain. I wouldn’t recommend having drainage installed unless absolutely necessary, as it needs regular cleaning to prevent clogging.
I believe your house is built too low in the terrain, and the waterproofing of the house was done poorly. The first is a planning error; the second is poor workmanship. Now they want to fix the poor workmanship by just applying something to the outside. That will not work.
This is how it should look, for example. The details may vary slightly depending on the manufacturer, so have your builder provide the appropriate specifications. You are entitled to this because the builder owes you a construction according to the manufacturer’s guidelines and the recognized rules of technology, which you can only verify with the detailed documentation (by having it checked).

@WilderSueden I can unfortunately only confirm that. At the back of the garden, VW Immobilien installed a water channel before the house was built, designed so that rainwater flows over the garden and into a sump. However, the house was set so low that the channel is higher than the garden, causing water to accumulate in the garden. That’s why the developer installed a cistern with a submersible pump in the garden after the first water damage occurred. Rainwater from the roof flows via the downspout into the cistern and is then pumped out. If a drainage system doesn’t help, what else should be done?
