Your finished floorcovering will only be as good as the substrate it is installed over!
This gym floor had similarities to a skate park with the amount of buckling that was taking place in the existing wood. High moisture in concrete is the number one reason for floor failures, as shown here in this 'before' photo at a school we recently started renovating.
We just completed phase I which involved demo of majority of the existing wood and wood subfloor system. We then shotblasted the concrete slab prior to installing a 2 part 100% solid epoxy waterproofing system from Schönox - A Sika Brand, and then primed and poured 85,800 pounds (1,560 bags) of a self leveling underlayment to build up the subfloor height for the new Tarkett Sports floor installation.
This past weekend we moved the bleachers away from the wall in preparation for phase II subfloor preparation where will be pouring 470 more bags to build up the next area prior to completing our installation and painting new game lines.
