Thickest we have ever done is 160psi but never bedded any line of the miles and miles put in and plenty are under trails, roads and ditches. Always just make sure there aren't any big rocks that could fall in first and damage. I even drive down the trench after filled to compact a little. Most is around 5' deep.
