Damping between shelves and sandbox


My turntable is sitting on a sandbox. On the top of the sand I have an inch and two inches thick maple board. Between these two wooden boards I am using cork coasters. I`d like to find a better solution, but I don`t really want to use glue. I am thinking to get a non slip mat, but searching for better alternatives.
What would you use?

Both, the turntable, and the int. amp sitting on a DIY sandbox and plinth. The plinth is a bit smaller than the box, so It`s not touching the wood corners but sitting on sand. But, handling sand can be messy sometimes.
What would you mix with the sand so It`s not creating dust?

@onhwy61 The thicker board is a bit wider than the sandbox, so I need to lift it a bit. It`s a really nice maple board, and I am satisfied with the sandbox, trying to keep the foundations. 
@bdp24 ASC`s solution looks good, I am going to contact them
@jab the surface is steady, it`s in a basement with concrete floor. The sandbox supposed to be a "sink" for the resonance coming from the TT. My integrated amp has it own sandbox also, but the board fits there.I found sand is -so far- the best solution for the base what fits my budget too. 
@millercarbon The mineral oil is going to do the job, good idea. What quantity you used for your box? I am considering between four footers, ASC or springs. I think it`s the best not to leave gap between the two boards or am I wrong?  I am keeping the board since it`s a really nice Shun Mook maple board, I really like it. I have tried granite, I think it was "ringing", but I guess I`ve messed up something. My phono stands on 5" MDF (6 layers glued and veneered) and thinking about to DIY it`s final sandbox soon. The bottom and the walls of the boxes are 2" MDF, but If I thought It would be good to upgrade later to real wood. Maybe I should drop the idea :) What footers would you use?
@geoffkait Would you set your springs in between two layers of maple? 
Thank you!
