Hello everyone,
attached are two pictures of the frost protection layer that has already been laid on our future paving area. Is this frost protection size appropriate, or should I apply a "levelling layer" with smaller aggregate before the bedding?
I am concerned that with the larger aggregate, I won't achieve a smooth and even surface after compaction, and that the 3–5cm (1–2 inches) bedding layer might be too thin, causing the frost protection to protrude.
Regards,
Jörg

No, there is a step/platform in the house.
Yes, exactly, so 10-12 cm (paving & bedding) and 10-15 cm new frost protection layer --> 20-27 cm excavation.
But only if it is necessary for frost protection. If you think that this frost protection layer alone will provide a proper substructure, I would of course omit the second frost protection layer.
