Concrete-free slab – Mesh under Advantech subfloor?
Some background: I’m building a small addition in Maine, Zone 6A. The floor will be concrete-free, with layers as follows (from bottom to top):
*stego 15mil VB
*2 layers of Advantech
I’ve read/watched most of the various articles/videos for concrete-free slab construction. There was one video in particular that used a plastic mesh product under the Advantech. I like this approach, however, I’m not sure which product would be suitable, and have not been able to re-find the video. I’m hoping that someone here might be able to recommend a product or steer me to the video.
I’m interested in adding the mesh for 2 reasons: If any moisture accumulates in the assembly it would not sit directly against the Advantech, and would have improved drying potential. Also, I’m considering adding a small access panel (in pantry) to allow pumping in the event there was ever flooding (plumbing leak above floor).
