Has anyone had any experience with using Durock tile membrane in a basement? It’s attractive because of it’s cost relative to Kerdi, and it’s ease of install and thin profile, but USG’s website doens’t make mention of basment use. It’s a “vapor permeable” substrate, but does that mean I’ll have water issues if I use it on a basement floor? What if I use it in conjunction with something like RedGard?
Any advice would be helpful.
