That's the gold standard when it comes to tile methods. Are you planning to submit your "system" to them? Just curious....and it's acceptable by the TCNA ...
Is your method going to come in a kit...or will you just be selling the information on how it's done?
I realize you're all cloak and dagger at this point... but I'm still not hearing anything revolutionary.
Pre-slope with backers
Vinyl liner over that to a clamping drain
Some kind of base over that for the floor tile
Backers to the wall with a liquid & mesh waterproofer
I'm curious about the cost as well. A mini unit of 9235 is still a pricey bugger (plus the mesh comes folded and creased which is a huge PITA). If I recall, the mini unit only does 30 sq ft. Unless there's a unit somewhere that just comes with the 6" roll of mesh. Even the liquid only hydro ban is about $100 a gallon.
As for using the liquid only products with a mesh... that sounds like using a product in a different way than it was intended. Hydroban was specifically designed to be used WITHOUT a mesh.
