@EveConiferous@shitpost_2049 Theoretically the house wouldn’t sink since its foundation is built on the stone, hence the pile foundation. The only problem with the sand is that it’s not porous enough for water to get through, so drainage and other problems would be an issue which is why sands not a good fill
@EveConiferous@shitpost_2049 I would have to disagree. The base of their foundation is not sand, it’s actually the stone. He is using a pile foundation which avoids the poor soil, the sand, to get to hard rock. Where I disagree with his design is that he should have used gravel backfill
