After stripping out most of the mess pic 1
The floor which I believe is the weakest point in all A/S, needed to be water proofed from leaks from above.
Also the floors need to be strengthened; I removed a rotted section, refastened with self tapping screws here and there.
I used epoxy resin and one layer of 6 Oz fiberglass cloth, just like a boat.
It only added 15 lbs, cost about $140 in materials. No odor or special equipment.
Time 4 hours.
The results are amazing I can walk anyplace and the flex is gone, rock solid.
Next 1/4" Promax insulation R-14 will be laid on top of the floor then, Pergo.
All the old insulation under the floor (the source of many problems) was removed.
