It depends. If your pool is leaking in an area where it’s washing soil away beneath the concrete slabs, then yes, it could be impacting your concrete. However, if your pool is leaking elsewhere, it’s not to blame.
The best way to know for sure is to have a concrete expert from FSS inspect your pool deck and suggest repair options. Depending on the size of the job, the work can be completed in a few hours and the area is ready to be used in just 15 minutes after installation.
