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.
