I am a licensed contractor and have used soil solutions a few times on Oil tank Decommissions,the first time we used them they took forever to finish the job, we had a hole in yard for like 2 weeks, finally after 3 phone calls we finally got them out to finish the job, on another job, However once they were out digging, they hit our main water line and broke it, luckly we have installed a bunch of these, but still its costs money mat & labor. but they at least finished in a timely manor. Just make sure they do a good locate so this doesnt happen,(its very common to have the water line or other utilites in the way, so keep that in mind if its close to something it is hard to excavate around a water line or other lines (average depths are placed at 2')
