Hello everyone,
I’m new here and have a few questions right away.
A few months ago, we bought a bungalow from the 1970s.
Recently, a contractor (renovation company) visited us and said we need to install a splash protection around our house to prevent moisture in the basement rooms. To save on costs, he recommended that we do the excavations ourselves.
So we removed some paving stones that were in the way and wanted to start digging (the contractor requires only about 30 cm (12 inches)?). However, right beneath the paving stones, there are concrete slabs about 3 cm (1¼ inches) thick.
My questions to you are:
- Is 30 cm (12 inches) really enough?
- What kind of 3 cm (1¼ inches) thick concrete slabs are typically found around a house, and can they be removed, or do they serve a purpose?
Best regards from Cologne

Hello,
Since when does a splash guard have anything to do with moisture in basements?
I always understood the gravel strip around the house, which I know as a splash guard, is only meant to prevent the facade from getting dirty from soil. The basement must be sealed with bitumen and dimpled membrane...

Hello Asatru,
please upload a photo so we can understand what you mean.
I understand splash protection exactly as @WildThing describes it. By concrete slabs, I mean patio or walkway slabs that should, of course, be removable.
If it really concerns the bituminous waterproofing on the exterior basement wall, this statement is extremely dangerous:
Soil from relatively deep excavations, for example at the basement wall without any slope or benching, tends to collapse and can bury anyone standing below.
There have already been several homeowners who tried to save money to waterproof their basement and lost their lives.
Best regards,
Yvonne
