another kerdi shower

kazm's picture

I am building a house in a poured concrete slab.  The section for the shower was voided and poured separately in order to get a good slope and create a curbless shower.  The inspector now tells me I must put in a rubber shower liner that goes 4 inches up the walls.  How can I do this with Kerdi? 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

easy answer is........ (post #207306, reply #1 of 4)

go to the Schluter site (or the JohnBridge forum) and watch the video on installs.

Eventho the floors are concrete you need to run a pan.  Some would say you could use a roll-on membrane offered by Laticrete, Custom and probably others.  But, there's still the problem of the "walls" you evidently plan on using to flank the shower floor.

Kerdi and others offer shower pans in certain sizes or you could use the kerdi product and 'build' your own.

 

But no way can you just dump water down a sloped concrete floor to drain and call it done..................

well, at least to pass an inspection.

Yes I know I have to (post #207306, reply #2 of 4)

Yes I know I have to waterproof but isn't that the purpose of kerdi?

I think you simply have to (post #207306, reply #3 of 4)

I think you simply have to show the building official some documentary evidence that certifies Kerdi's ability to perform as a pan liner. Visit their site and look for it. If it is not readily available or obvious, then visit the johnbridge.com website and ask there for some guidance. That site is frequented by many contractors who have run into the same sort of uninformed official.

You must have quit reading too early.

further in my post to was this:

I would also run that Kerdi membrane out the "opening" and around each side wall for water that might get past the opening.

 

You can present the inspector with the back up from Kerdi and show him you intend to properly seal the corners, run the membrane into the "pan style" drain and also run kerdi up the side walls 6" (4 just seems short to me, eventho there's no curb.
