Hello Haralanov,

That's a nice strong heavy box you have there.
You might want to check and add some more sand in the future because vibration helps the grains to adjust which in turn reduces volume.

You might try to bare into the sand some plastic air bubbles from packing material…. If you feel that you are too crazy then I need to disappoint you saying that I know people who pressurize the enclosure and pump inside of the box a replenishable inert gas…


As an alternative to Romy's suggestion you could try a mixture of sand and polystyrene beads as this will prevent the sand to become a compact mass.


Cheers,

Tuga
