Hello everyone,

this is my first post in the forum, so please bear with me if not everything is described correctly.

Last November, we bought a house from the 1970s, with an extension from the 1980s that needs renovation.

On May 30th, we experienced heavy rainfall events in NRW, which caused water to enter the basement (about 3cm (1 inch) deep). In the meantime, we found out that the water came through the masonry. After drying the interior, we started working on waterproofing the basement from the outside. During this process, we noticed that a bitumen layer had already been applied, as well as polystyrene insulation. Overall, the basement is dry.

Now to the main questions. What is the best way to proceed? I have already excavated the ground down to the horizontal damp-proof course and removed the old polystyrene. On the web, I found two products that seem suitable for exterior wall repair.

1. pci barraseal® turbo
2. MEM Express-Dicht

Which of these two products is better suited for the work?

I would also like to renew the insulation. What do you suggest here?

Attached are some photos for a better understanding.

Thanks in advance for your help and advice.

Best regards
Patrick

Can anyone tell me approximately how much something like this would cost if done by a professional company?

Hello Katrin

No! Nobody can tell you that before a detailed assessment is done. The damage could be caused by a hole that wasn’t properly sealed anymore and can be fixed with just a few steps, or by widespread settlement cracks caused by a sunken foundation.
It’s more or less like asking, "how much does a car cost."
