We had a gunite pool completed about this time last year 2010. Within 3 months the pool was cracked and is currently about 2 inches out of level length wise and 3/4 in width wise. The pool is 16x32. The soil is clay and is considered expansive. This has caused pipes to break. Has anyone had experience with this problem. Suggestions on possible solutions to stabilize the pool and maybe to bring it near level would be appreciated. Thanks in advance.
