ᐅ Rising Damp on the Exterior Wall (Black Tank Waterproofing)

Hello everyone,

We have been living in our newly built house (turnkey, through a developer) for three years. Yesterday, after the damp weather, we noticed this on our facade as well as on the facades of our three neighbors. We all have the same type of house.

A waterproof tank (black tank waterproofing) is installed.
An acquaintance suggested that the brick edge is too close to the wall, causing moisture to seep behind the facade.
Could that be correct?
Dimple membrane (dimpled membrane) is installed.

The warranty is still valid for another two years.
There is a bitumen coating, but I’m not exactly sure how high it goes. I would have to check the old photos from the construction phase.

Looking forward to your feedback.

It could also simply be sprayed on. You don’t have any spray protection at all.
Windward side?

To be honest, I don’t really know what a splash guard looks like.
How can I check for that?
Or how can I tell if it’s splash water or rising damp?

You have installed a hard flooring surface right up to the plastered facade. When it rains, water splashes onto the facade. One common solution is to use gravel strips, for example.

Is this the side exposed to the weather?
I assume you also have floor-to-ceiling glass there. After the rain shower, was it not wet at about the same height by any chance?

No, it’s not the weather-exposed side... and I don’t have tall, deep glass. Otherwise, it would be obvious.

Hmm...

I’m uncertain if it’s really splash water... I should probably place a bucket against the wall and after rainy weather, move the bucket and check if it is splash water.
