HDPE double wall pipe

Anybody have any experience with this product. Looking to doing a bunch of field/pasture crossings with it and wonder how well it stands up to loads. Shouldn't be much more than 10 ton loads with 15 tons max. I read on other sites where quality and depth of fill on top is the key factor. At least 12-18" of quality sand/gravel. I have used galvanized culverts up to this point, but they are far to pricey around here for small, occasional crossings. :cowboy:

Have a couple of these for 5-6 years. Several 18 wheeler loads of feed across them a year with no problems. Maybe 12" of fill on top. Mine are 10" diameter.

been installing it for yrs in storm drainage systems and I also use it for culverts
main thing is get plenty of coverage
I prefer 2" rock for coverage at least a ft thick then cap it with smaller rock

If you put at least 18" of fill on top of it and keep it at that level or better then you won't have problems. Fill depth is the key to all pipes. I have put many in and we will have gross weights over 80,000 lbs and no problem. Gravel will help keep from eroding this depth down to the critical area and you will know it when you get there.
