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.

Urutan pekerjaan yang direkomendasikan

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.

Hold point: Membrane application should not start until slope, substrate and penetration details are accepted.

Alat, peralatan dan akses: 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.

Hold point: Do not tile, screed or cover until membrane thickness and critical details are checked.

Alat, peralatan dan akses: 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.

Hold point: Finish works should not proceed until test result, protection and photo evidence are complete.

Alat, peralatan dan akses: Water test kit, Stopper, Moisture meter, Protection board tools

Norma konsumsi material untuk perencanaan

Rentang konsumsi adalah benchmark perencanaan. Kuantitas final harus dicek terhadap gambar, spesifikasi, kode lokal dan data supplier.

Material atau resource Basis Rentang rencana Unit Catatan
Liquid waterproofing membrane Waterproofed area 1.5-2.5 kg/m2 Use supplier dry-film thickness for final quantity.
Primer Prepared substrate 0.15-0.30 kg/m2 Depends on porosity.
Corner tape Internal corners and movement joints 1.00-1.20 lm/lm Allows laps and waste.
Protection layer Membrane area 1.05-1.15 m2/m2 Required before high-risk follow-on trades.
