Any advice, hints, or tips on building a platform/sub-floor for our wrestling room would be appreciated. Does anyone have any plans or specifications?

Coach we use the blue 4x8 sheets of insulation, used for houses. I think it is an inch thick. I really like it, zero issues/problems, seems to keep the mats dry, etc. It's not cheap, but also seems to soften the mats. Let me know if questions.

We purchased foam blocks with adhesive on them and put them on the back side of plywood to create a subfloor that had some "give" to it. I have also used plastic pallets in my barn which has significant forgiveness.

Mr. Cokeley, where did you purchase your foam blocks?

we used 3/4" plywood on 1/2" furring strips for the base, then 1/2" resilite foam glued to the plywood. Pretty expensive but made a very good solid floor with a sufficient give.

Regan, did you put the insulation on plywood, and how did you bond to keep from slipping?

Thanks for the insight
so did not use two layers of plywood since you used 3/4"??
I'm planning to use 3x3x3 foam blocks and two layers of 3/8" plywood
still pretty expensive also

just one layer of plywood, raised slightly on strips to allow air flow under and a little spring. Nothing cheap about doing it right.
