Major Issues with an Unlevel Pool
The pool will twist, buckle, or even collapse, causing property damage and injury to anyone in or around the pool. Also, the inflatable ring pools are more likely to fold under the force and blow out causing major damage and a safety hazard.

You have three options: coat the sunken section with a sand-and-cement mixture to make the surface higher, raise the sunken section using a process called mudjacking, or raise the sunken section using expanding polyurethane foam.
