Hello Basti The offer is too vague for me. Is the price for the material already included? Is the compaction as requested? You can also unload and spread the material. Then go over it once with the vibrating plate. It is then compacted as well. But not properly. That should be specified exactly. Especially if such a bargain price is offered. Steven
Hello 305er There is a small mistake in thinking. The RCL or Z/0 is finely crushed construction debris. It is used for backfilling under the floor slab. I wouldn’t dump that in the garden. You could maybe get material from the neighbors. And then 30cm of topsoil. Steven
