Hello everyone,
I am an absolute beginner when it comes to renovation, also already 65 years old, and therefore can no longer do endless amounts myself. Besides, I simply lack any knowledge, although my wife and I have been researching intensively for weeks in the numerous forums dealing with renovating and restoring, especially old buildings. But you don’t really become proficient there either—because you have been a theorist in this field all your life or even less—so basically completely clueless.
I hope I’m in the right place with my question now. I have also posted some pictures with the question so you can better imagine it.
Fact: Parents’ house from 1955, actually good building substance (father was a mason), only the basement is damp, at least on the walls, especially where the outside stairs lead into the house.
We have already had some experts here who, of course, only want one thing: open up outside, possibly remove the floor inside, injections into the wall—the whole program. We should budget around 40,000 euros. That would be almost total damage, and we really don’t want to accept that. Some non-professionals said the basement isn’t that damp... it could be done cheaper.
Regardless of whether we now dig everything up or want to “inject” from the inside, I first want to do something else because we have to postpone the major construction site anyway for personal reasons. But at least I want to prevent rainwater from continuing to penetrate especially at the stair entrance and in the cracks between the house wall and the floor. The pictures illustrate this quite well.
Now the question: How do I best close the mentioned cracks and this hole at the stair entrance (even if only temporarily)? I have read a lot about everything from simple mortar to 2-component epoxy resin.
Do you have any experience and knowledge that can help me?
I would be grateful for any tip!
Best regards, Kalli
