I've searched everywhere on this site as well as on google (which just leads me back to this site) and have not been able to find an answer to my question. I've got an in ground salt water pool in our back yard and the diving rock is coming loose. You can put one foot on the rear and one on the front edge and the rear will come up about 1/2". Its pretty scary thinking that the rock is going to follow someone in after a big jump. What do I need to do to re-secure the rock? Do I just need to pry it up and use adhesive for rock and concrete to glue it back down or are there rebar rods going through it which would add difficulty? Any suggestions would be greatly appreciated.
