ᐅ Concrete slab partially removed, reinforcement exposed

Hello,

about two weeks ago, the footing slab for our house was poured. Overall, the work seemed very clean and solid, as far as I can tell. This week, the masonry work on the ground floor started. During this, it was discovered that the formwork for the footing slab was not properly squared. As a result, on one gable side, the footing slab slightly protruded below the masonry. The overhang increased along the width of the house from 0 to about 6cm (2.4 inches).

Now the general contractor has chiseled away the overhang along the house width. The reason given was that otherwise the insulation would not fit. The background is that we are also having brick cladding. The bricks will rest on a frost guard approximately 80cm (31.5 inches) deep.

Where the footing slab was chiselled away, the reinforcement is partially exposed. How should this be assessed? Is it sufficient to coat it with bitumen waterproofing?

No, probably not. But if someone claims to have worked according to DIN standards, they must have them and be able to prove that the criticized point is actually compliant (by showing the specific section in the DIN). That’s how I was able to put pressure on everyone involved during the construction, and they had to make corrections. Because nobody actually had those standards ^^

If things get really serious, of course, you can buy the standards yourself or work for a company that has a DIN subscription. Otherwise, for many well-known DIN standards, there are explanatory documents available that include excerpts from the original part as well.

Are DIN standards now freely accessible?

Yes, although not for free. However, you can often find a library nearby that provides access.

But it must be a very, very well-organized library. Even our university library had maybe 5.

No wonder the university library doesn’t have a printed copy.
University staff can easily access any DIN standard online and download the respective PDF.

You are underestimating the commercial aspect of the German Institute for Standardization... it is not an academic charity organization.
But sure, with a bit of effort, you can get them.
