Our shockrete pool was installed in Spring 2012 in northern Ohio. We live on a hillside overlooking a large river, with an approximate 56 foot drop from the pool level to river level, on a tiered design. There is approximately 15 feet from the pool edge to the first drop, but that drop has dozens of large, flat boulders installed as a retaining wall for the top level. Approximately 4 years ago, we started noticing more-than-usual water loss, which developed into cracks, then repeated cracking, then severe cracking, and now that plus severe separation of the deck/coping area. We reported it to our builder (who also did the weekly servicing) immediately 4 years ago, and they've patched the cracks and painted the pool multiple times, but they really don't know what's causing it or how to fix it once and for all. Our area doesn't seem to have engineering firms willing to do residential work of this type. Not really sure where to turn to get some help to (1) identify a root cause of all this; (2) suggest whether it can be repaired or if it's a re-build.
