John Whipple - By Any Design ltd. Thanks Bud. You and I might know this bud my expeirence of the past three years is that online researchers are in a hurry. They want info and right now.

When I look at your drawing I see a mock up quite close to what we use in the field here in Vancouver but not with a traditional mortar bed and liner and not at 2" off recess.

Traditional liners and mortar bed's require a pre-slope under the liner and a good 1 1/2" of mortar above the liner. Your detail shows more a Quick Drain USA type install and as drawn 2" is too much for that.

I see and help many people every month who have read online instructions and worked themselves into a corner. I would love it if you tweaked this drawing to include more detail and some direction on seeking out a structural engineer.

Thanks.

John Whipple
