I have a recent post concerning a contractor I hired to build a 2.5 ft granite rubble type wall mortared on the back side. I live in Atlanta and have red clay soil. He maintains he needs no gravel footing or footing of any sort for the wall while I believe there should be a foot of compacted gravel beneath the wall which should be 1/3 wider than the wall.
I even dug the trench around where the wall will go and he says now, he can’t guarantee it if there is gravel underneath it because it will shift.
Am I crazy? This guy comes highly recommended and I’ve seen his work, but I just can’t believe that he will only guarantee it if laid directly on the ground?? He says he has done it this way for 25 years. I’ve already paid 1/3rd down for him to start work and he delivered about 12 tons of rock to the site. Is this serious enough that I should consider another contractor?
Thanks in advance.
