I'm just finished assembling and joining my PVC drain pipes for a linear drain installation.
I'm now prepping for my single slope mud bed, and was planning on burying the PVC pipe in it. The thickness of the mud will be 12cm on the high side, descending to 9cm at the drain. One potential issue I see now is that there will be a relatively thin layer of mud on top of the PVC pipe after the mud bed is finished, and I'm worried that this weak spot might cause a crack. By thin I mean around 3/4 inch.
As a DYIer I'm trying to come up with perhaps non-standard solutions so bear with me, but here are some thoughts:
Here are some illustrations to assist.

As a DYIer I'm trying to come up with perhaps non-standard solutions so bear with me, but here are some thoughts:
- If I pack the mud really tightly around the pipe, and perhaps rest the pipes on something something to minimize downward flexing, will this be enough?
- If not, I thought of making a regular wet mortar mix and pour over the entire are to cover up to the top of the pipe. After it cures, place a layer of plywood on top, and then build my sloped mud bed. The mud will still be quite thin at the drain end, but this way, I'll decouple the mud bed from the pipe by use of the plywood, so that any cracks below will not transfer to the dry pack.
- Also, are there any issues with burying the pipes in either wet or dry mortar? Do they need some protection in the form of a sleeve?
