Bad Concrete in Fence Post Holes - Advice?
We had about 30 6x6 10ft posts installed about 3 weeks ago. Fence guys showed up with a mini concrete mixer trailer (they mixed at site). They went down 3 feet with the holes and poured concrete.
Currently the concrete still appears very damp and crumbles when I tap it with hammer. When I broke a piece off, I found twigs in the concrete. I assume they tried stretching the batch will backfill soil (clay) and extra water.
Question is, Can I ignore this? I've heard of people using gravel instead on concrete which is kind of what I have now. I live in Saskatchewan Canada where the winters can get down to -35C. Just concerned how the fence posts will look after a couple of years.
Thanks in advance
I would have him redo the work if possible. The dirt itself will actually settle and tighten the post fine but that is not what you paid for.
We're probably in the same climate zone as you are (Zone 7, I think) and here, we put the fenceposts down 4 feet, to account for frost heave...Now we get winters, but nothing like your winters so I would have thought 4-feet deep to be standard, but I guess not. Was there a contract?
