Hello,
what is your opinion on buying recycled crushed stone for the house’s foundation slab? We need to overcome a relatively large height (1.2 m (4 feet)), and this could save a considerable amount of money. So far, I have heard mixed opinions but no real explanations.

Yes, it should all be specified in the structural calculations In your post, you only wrote: "first, lay down about one meter of fill sand"
That’s why I pointed out that it’s not that simple!

In commercial construction, it is common practice to demolish existing buildings and process the debris on site into gravel. This gravel is then used for backfilling.

Oraclefile10 Sep 2021 17:23Thanks in advance for the numerous replies. At first glance, this sounds very promising. Firstly, raw materials are reused, and secondly, it apparently saves a significant amount of money. According to our soil survey, the use of recycled aggregate is also allowed and should hopefully not pose any problems. Of course, the planning will be professionally handled on site, so I can’t say much more at this point. However, since two earthworks contractors we consulted, without knowing the site conditions, opposed the use of recycled aggregate, we were a bit surprised.
Assuming the soil survey and structural engineering report give the green light, is there nothing against using it?

So part of the savings will be offset by that cost. I’m not bothered by the recycled gravel, but it does sometimes contain quite a bit of debris.
