What pipe is this?

[arkham]

It was installed as a drainage outlet, under a couple inches of gravel running under my soon to be driveway. It seems flimsy to me, and is very flexible (that's my foot distorting it with very little pressure). It's black on the inside with a white coating, and the walls are about 0.07" thick.

I couldn't see anything like this on Lowes or Home Depot web sites. I want to make sure I don't have a problem before I pave over it.

Thanks.

I believe that is Hancor 4" x 10' Polyethylene Solid Drainage Pipe, which can be located at Lowe's. Here is their picture:

If your going to have a driveway over the line I would change it to sch 40 PVC. It will stand up far better.

At least swap it out for SDR 35 but SCH 40 will be better.
