Is that a yes or a no? :shifty:

my thought: Why the hell would you do this? Cement board is about as waterproof as a sponge.... Is there some special new cement board that is somehow waterproof and non-porous? Don't tell me it's that new foam backer board :no:

The technique does use a waterproofing in it. No it's not Fin panel. The reason I have come up with it
is that I see the "old school" mud sets not being taught properly. The dinosaurs like myself are dying off and the younger tradesmen are not learning from qualified teachers.

I checked the search box and can't seam to find any threads that talk about it. I just was fishing to see if there was any interest in using stock off the rack cement board ( PermaBase - Durock) to build a 100%
waterproof shower pan.

Not a good idea.

I can see the problem with we young folk forming the base wrong as it would screw up the tile work, but there's always a hot mop underneath, so water leakage shouldn't be an issue. I'm still confuzzled

I am new to this forum and new to the tile trade 39 years ago. I know that this is not the place for advertising. I have figured out a way to use cement board as the shower pan. I will be attending the "Total Solutions" conference in San Antonio in Sept. given by the NCTA and after that I will be using this sight to PURCHASE advertising space and with that display the website link so anyone can check it out.

My question is :

I wanted to know if anyone has seen a post that discusses the use of CBU INSIDE the shower AS the pan.

Are you talking about using CBU for the pre slope?

If so, that's not a new idea.

Please don't take it wrong that I meant the younger tradesmen are not as "skilled. The technique I have
come up with would allow a homeowner with a skill level of say 4 out of 10 do this. No hot mop! The base
is waterproof. Old school mud set used pre-pitch mortar and vinyl liner because they knew that the tile
and grout were NOT waterproof so they expected them to allow water through to the liner and then (in a perfect world) to the weep holes. Since my method is 100% waterproof BEFORE tile it works the same way with much less skill required to get a preferred pitch towards the drain. In all due respect Mel, allow
the possibility to re-think "the way it's done"

let's see the specs and I will submit them to my building dept. :thumbup:

ChrWright , You say that using CBU as a pre-slope is not a new idea. How is it used like this?

Ancient Chinese secret... :shifty:

Kevjob , We are still in the launch stage and have already been contacted by the TCNA for the process to get it into the handbook. That takes time. Your building Dept.will see specs when it makes the handbook

ChrWright , I hear you. That's what I'm talking about.Atleast you are thinking outside the box.

Many people steer me to the Schluter website. I can build a 48x34 shower pan complete for about $200.00
I don't have to order the materials and can pick them up at any "big box" store. Schluter makes great products, but they cost alot more. Next , someone will tell me "you get what you pay for." If you can do the same job for less money that makes sense to me

Ray D , Do you have anything to add?

Good Night Everyone, Thank-you for your comments. Unless a man is willing to listen to other views he will not be able to learn from others wisdom. I do appreciate the wisdom that this forum will bring. I will check back often.

schluter 48x48 shower pan and kerdi installed all corners and dams etc.. 45-60 mins, old school style 3-4 hours with blocking,tar paper, lathe, pre-slope, liner, pan test wait for inspection, final mud layer and curb construction, I can save approx 3 hrs of manual labor and no heavy materials to lug up stairs and:clap: no box stores. :thumbup:
