During the dig of our DIY pool we have struck gravel, the gravel ranges from Pea Gravel to large rock the size of 2 fists all mixed also with some clumps of clay, when wet it moves easy, ie when I stood in it I sank about an inch as the gravel displaced around my feet. Now that it has dried it is fairly hard. This goes for about 1/2 the width of the pool to 1/2 the length of the pool. I didn't dig most of the hopper because of this, but now that it is dry I can finish off by hand (not looking forward to that) the rest of the deep end. The shallow end was solid clay the full width - so no issue there. It looks like the half end that I chose for the deep end was back filled many years ago as I also found broken bricks etc.
So now that I have a huge hole in the yard, is this gravel mix an issue, can I construct the pool on top of this? I will have this inspected by local authorities on Monday so would like it fixed by the inspection if possible?
Other than that the dig went fairly well, a little leveling but not too much, hopefully the kit will arrive this week and the inspection goes well I can start putting up the walls this weekend and bolting it all together.
Thanks for any help.
