Waterproofing work sequence

Waterproofing succeeds or fails at interfaces: substrate, corners, drains, penetrations and movement joints. The sequence must keep details visible until they are inspected and tested.

Secuencia recomendada de trabajo

01

Prepare substrate and details

Make the base clean, stable and shaped for water movement.

  • Check slope to drains, surface strength, moisture and crack condition.
  • Form coves, corners, upstands and pipe penetration details.
  • Prime only after dust, laitance and loose material are removed.

Punto de control: Membrane application should not start until slope, substrate and penetration details are accepted.

Herramientas, equipos y acceso: Moisture meter, Scraper, Vacuum, Primer roller, Slope gauge

02

Install membrane and reinforcement

Create a continuous system through field areas and critical details.

  • Apply the specified coats, sheets or membrane system at required thickness.
  • Reinforce corners, drains, joints, pipe sleeves and thresholds.
  • Protect fresh membrane from dust, trades and mechanical damage.

Punto de control: Do not tile, screed or cover until membrane thickness and critical details are checked.

Herramientas, equipos y acceso: Wet film gauge, Detail brush, Roller, Membrane scissors, Joint tape

03

Test, protect and release to finishes

Prove the waterproofing before it becomes inaccessible.

  • Carry out flood, ponding or local water testing where suitable.
  • Photograph drains, corners, upstands and penetrations.
  • Install protection before screed, tile or equipment installation.

Punto de control: Finish works should not proceed until test result, protection and photo evidence are complete.

Herramientas, equipos y acceso: Water test kit, Stopper, Moisture meter, Protection board tools
