Pipe Installation in concrete slab 1

[aghazawy]

Is it acceptable to install high pressure UPVC pipe within a concrete slab.

the application is for swimming pool water supply piping system.

Why are you suspicious of allowing this installation?

 

[aghazawy]

this is due to site conditions, in addition to recommendations from pool service's suppliers.

i am worry about the life time of the pipe which may be affected by the direct contact with the concrete, specially at the time of concrete pouring.

UPVC is susceptible to damage from impact of the aggregate if concrete is dropped on it. You also need to make sure the pipe is properly supported and doesn't become bent. Also at the transition from concrete to other soil there is a risk of failure due to sheer and stress concentration.

Have you considered PE or UHMW PE, These are much more forgiving of impact and are inherently more flexible.

If you could use a bigger pipe as a dict then insert the main one or use a flexible pipe in that section might solve many of the issues.

How high is this pressure?

Schedule 40 is the most common piping material for residential underground pools. Piping options include ABS, Schedule 80 PVC, CPVC, and Schedule 80 PVC.

PVC water pipe and PVC electrical conduit are also commonly installed in concrete.

When I have seen these material embedded in concrete (passing through it) it has always been inside of a larger pipe. The larger pipe could be plastic also or sch10 steel.

Typical construction for a residential pool consists of PVC pipes embedded in gunite.

It is also common for PVC conduit to be in the concrete:

Special thanks to Mr LittleInch for his kind threat

thanks again for all.

PVC in pipe grade is usually Type 1, Grade 1 unplasticized (sometimes referred to as PVC-U or uPVC in Europe), more recently classified as Class 12454-C. ASTM D 1784.

bimr, but none of those examples pass from the soil into concrete. The possibility of shear loading bothers me. Fully embedded or just emerging into air I don't see any problem.

I went into my basement and looked. Where my plastic waste lines pass through the floor they are inside a collar that is set in floor, and there is a sealant between the two.

EdStainless, the pictures above don't show it, but how do expect the bottom drain pipe to leave the pool.

Anyway, here are some better pictures showing PVC pipes going through the gunite into the earth.
