Waterproofing system
Swimming Pool Waterproofing Systems
Swimming pool waterproofing systems combine a continuous shell barrier with detailing at lights, inlets, floor-wall junctions, and movement joints. Petroseal supports cementitious under-tile systems and polyurea options where specified. Flood testing before finishes is recommended when required by the designer.

FAQ
- What is the best waterproofing under swimming pool tiles?
- Cementitious systems are commonly used under tiles. The correct choice is the one approved in the project specification for the shell and finish.
