PETROSEAL

Application

Swimming Pool Waterproofing in Pakistan

Swimming pool waterproofing must create a continuous watertight shell before tiling or other finishes, with particular attention to floor-to-wall junctions, lights, inlets, and expansion joints. Petroseal supports pool projects with cementitious waterproofing systems under tiles and polyurea systems where a seamless elastomeric lining is specified. System choice depends on structure type, finish, chemical exposure, and consultant details — not on marketing labels alone.

Technical requirements

  • Sound, cured concrete shell within specified moisture limits
  • Compatible primer and reinforcement at corners where required
  • Flood test before tiling when specified by the designer

Limitations

  • A verified Petroseal pool case study is only published when project records and photos exist
  • Tile adhesive and tile selection remain the finishing contractor’s responsibility

Application sequence

  1. Confirm shell readiness and crack map
  2. Select cementitious or polyurea system
  3. Treat joints and penetrations
  4. Apply waterproofing, cure, flood-test if required, then finish

Common failure modes

  • Waterproofing stopped short of fittings
  • Movement joints not detailed
  • Tiling over uncured or incomplete waterproofing

FAQ

Why do swimming pools leak after tiling?
Common causes include incomplete waterproofing at penetrations, cracked shells, failed joints, and finishes applied before the waterproofing system has cured or been tested.
Is polyurea suitable under swimming pool tiles?
Only when the full system (primer, polyurea grade, and tile interface) is designed and approved for that finish. Many tiled pools use cementitious systems under tiles instead.
