PVC toe drain
PVC toe drain
(OP)
I've been browsing online for a good website that lists PVC pipe types (EG. SDR 17) that measure up in accordance with particular ASTM standards (specifically F 949 and D 3034).
I've come across manufacturer's websites that have grids of their products and explain which standards they meet up to.
But does anyone have a good reference of a multitude of pipe types, or is it necessary to check pipes against the standards as I come across them?
Also, where could I find information in regards to design life of particular types of connection joints (cement vs gaskets)?
I'm a new EIT at a design firm and have been put to the task of coming up with a permanent toe drain solution for an embankment improvement. I'm not entirely sure of where to start. I've been researching a bit, but thought this may be of use as well.

Perforated toe drain will be either 8" or 10" and approximately 5000 LF. Depth below surface is between 4-6 feet. The embankment is considered a high hazard potential. Causes of concern are expansion and contraction due to seasonal temperature changes causing cracking and joint leakage. Rigid joints are desirable.
I've been comparing corrugated HDPE vs PVC and other than the price, corrugated HDPE seems better in nearly every way, especially in durability with cold weather. This pipe won't be buried below the frost line.

PVC is a lot more brittle.

Insight on joints would be much appreciated.

I've seen welding used for the solid HDPE pipes used to carry various liquids and slurries long distances around phosphate mines when I was in Florida. They always appeared to work well, but for a perf'd toe drain (which needs to be sand-tight, but not water-tight), I'm not sure there is any justification for that next increment of cost.

Resins shall conform to the minimum requirements of cell classification 345464 C as defined and described in the latest version of ASTM D3350 "Standard Specification for Polyethylene Plastics Pipe and Fittings Materials".

HDPE is more difficult to install correctly because of the flexibility. PVC will be better if everything isn't backfilled exactly right.
The gasketed PVC is also easier to install correctly.
