We use landscape bricks to hold the rebar up off the rock so we know we will get the proper amount of cement under and around it.
We finish up other "shnibbly-bits", like setting the main drains to height, plumbing the skimmers, and adding the "key-way." The key-way is what the pool deck will rest on ensuring it does not sag.
Steps are framed in, all rough-in plumbing is done, piano-wire is set. We just need some mud!
