I'm building a server room that is using plywood as its flooring, which unfortunately is infested by woodlouse, wood beetle, or some kind. I realize it just after the floor is finished being installed.
Since it is impractical to replace the flooring, I'm thinking about apply a new layer, rubber or vinyl flooring on the top of the plywood. The question is, will the insects, bugs, louse, or termites able to penetrate the rubber or vinyl layer? Or is there any more practical alternatives?
Would like to put in a suggestion for either Schluter Ditra or Laticrete Strata-mat.
As uncoupling membranes, they effectively stiffen floors by unitizing the tile layer. For stone installation, Schluter recommends double layer of underlayment. The second layer should be offset from the first layer, not following seams. The second layer should only be attached to the first, not through to the framing. The total thickness only has to be 3/4, but can be thicker as necessary for level matching. The first layer should be at right angle to the joists, along the the long direction of the ply.

Sturd-I-Floor is the "Standard/Grade" in this case. It's a little murky for anyone old enough to expect the A-B-C grading. But it's designed for the job you want to do.

well, I decided to tear down everything and replace it with concrete and granite floor. If I overlaid the infested floor, the pest would just eat the plywood until it was completely deteriorated
