We wanted to install some Mats to help out with both Judo and
our son's wrestling. So.... we did.
With a quick search of the internet we found:
The Denver Dojo Inc Best workout floating floor system.
They were a big help in getting us started.
The mats came from Dollamur via Amazon. The mats are the same ones
that Mike Swain uses.
We ended up getting the closed cell polyethylene from:
The Foam Factory.
A quick trip to Home Depot for the plywood and we were ready to go.
We ended up going with 4"x4"x1.5" blocks.
Here's the rough plywood and foam layout:
We ended up counter sinking 6 metal brackets into the plywood in order to
avoid using two layers of plywood. So far it seems to have worked well.
You also notice from the pictures that I ended up hinging the two 4'x5' sections.
This was done so that we had access to our pump room door.
