In the Weberhaus we purchased from 1994, we discovered an open gap in the ground slab during the bathroom renovation on the ground floor:
I am wondering what the purpose of this hole is, since no pipe runs into it. Could it be a planning or construction error?
In the original documents, I see several openings in the foundation, so it is possible that others may also be unsealed:
The waterproofing as required according to DIN 18195 would presumably not be sufficient under these circumstances? According to the following quote from the contractor for the floor slab, these and possibly other existing openings should have been sealed!?
Do you see any risks that moisture or similar issues could have caused damage to the floor and wall construction? Should this be inspected by a professional?
Most importantly, what is the best method to close this hole? Bitumen, epoxy, ...?
Does the wall or the wooden beam need treatment, drying, sealing, ...?
Thank you very much.
