Base plate

Hello

so the dice have been cast for gravel.

Hello

two or three questions for the practitioners:
The usual material for the capillary-breaking layer here is limestone gravel 0-45. Now I have calculated that I need 4.1 m³ for a 15 cm layer. A lot of volume is lost due to compaction. I plan to order 5 m³. Is that enough?
Now about compaction: I have a vibrating plate. But it only weighs 60 kg. I imagine placing the limestone gravel in layers of 3-4 cm and then vibrating. Is that realistic, or won’t I be able to compact the layers properly?
I built a 20 kg tamper. How does that look? After five minutes of tamping, my tongue is hanging down to the floor, but should I tamp again after vibrating?

A load-bearing reinforced concrete slab will be placed on it. From experience, I would say that your compaction with the vibrating plate is sufficient. The compressive stress will not be very high, as you are creating a very large area.
