Waterproofing & Membrane Installation SWMS
Waterproofing and membrane installation for wet areas, roofs, podiums, and below-ground structures — sheet membrane, liquid-applied systems, hot bitumen, and surface preparation.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Waterproofing and membrane installation covers a broad range of high-risk tasks including sheet membrane application in wet areas, liquid-applied systems on podiums and balconies, hot-applied bitumen on roofs and below-ground tanking, and the substrate preparation that precedes each system. The work routinely combines solvent-based primers, two-pack polyurethanes, open-flame or hot-pot bitumen kettles, and elevated or confined work environments — a hazard profile that engages multiple duties under WHS Regulation 2025. Because the work involves hazardous chemical exposure, hot works, and frequently work at heights above two metres, it meets the threshold for High Risk Construction Work under WHS Reg 2025 s291. A documented Safe Work Method Statement is therefore mandatory before any work commences, must be developed in consultation with workers under s47-49, and must be available for inspection by the regulator throughout the task. This SWMS template addresses each system type and the cross-cutting hazards of fumes, heat, and falls.
Hazards identified
7 hazards covered, sorted by priority.
Acute CNS depression, chemical pneumonitis, long-term hepatotoxicity, and breach of WHS Reg 2025 s49 exposure standards
Full-thickness burns adhering to skin, permanent scarring, potential amputation, and notifiable incident under WHS Act s38
Fatal or catastrophic multi-trauma injury and prosecution under WHS Reg 2025 s78 fall prevention duties
Irreversible occupational asthma, permanent respiratory impairment, and workers compensation liability under occupational disease schedule
Structural fire, fatal burns, third-party property damage, and breach of AS 1596 LPG storage and handling code
Acute lumbar disc injury, chronic musculoskeletal disorder, and breach of WHS Reg 2025 s60 hazardous manual task duty
Fractures, head injury from falls onto wet substrate, and notifiable incident under WHS Act Part 3
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Specify pre-formed factory-fabricated waterproofing pans for shower bases where possible to eliminate on-site liquid membrane and primer application entirely.
- 2Elimination — Schedule membrane works before roof structure or balustrade removal so permanent edge protection eliminates fall exposure during application and curing periods.
- 3Substitution — Replace solvent-based primers with water-based or low-VOC equivalents complying with AS/NZS 4858:2004 to reduce inhalation and flammability risk in wet areas.
- 4Substitution — Substitute torch-on membrane with self-adhesive or cold-applied liquid systems on combustible substrates to eliminate naked flame and hot bitumen exposure.
- 5Engineering — Install mechanical extraction ventilation achieving minimum 10 air changes per hour in bathrooms and lift pits before primer application, monitored with calibrated VOC meter.
- 6Engineering — Erect perimeter guardrails to AS/NZS 4994.1 on all podiums and roofs over two metres, with covered penetrations rated for 100kg point load.
- 7Administrative — Conduct daily pre-start SWMS sign-on, SDS review for the specific primer batch in use, and hot work permit with 30-minute fire watch post-torch operations.
- 8Administrative — Rotate workers between primer application and dry trades at maximum two-hour intervals to keep exposure below WHS Reg 2025 Schedule 10 workplace exposure standards.
- 9PPE — Wear A2P2 organic vapour respirator fit-tested to AS/NZS 1715, nitrile chemical-resistant gloves, and Tyvek coveralls during all primer and liquid membrane work.
- 10PPE — Wear heat-resistant leather gauntlets to elbow, face shield, leather apron, and lace-up boots with covered tongue during all hot bitumen decanting and application.
Applicable Codes of Practice
Sets product performance and application requirements; triggers PCBU duty to verify installer competence and primer compatibility with substrate per clause 2.4.
Mandates SDS register, exposure monitoring, and ventilation controls for solvent primers and isocyanate membranes under WHS Reg 2025 Chapter 7.
Triggers hierarchy of fall controls for membrane work on roofs, podiums, and balconies above two metres under WHS Reg 2025 s78.
Governs LPG cylinder placement, separation distances, and securing requirements for torch-on bitumen operations on construction sites.
High-Risk Construction Work triggered
Membrane installation on podium slabs, sloped roofs, and balcony edges routinely places workers within two metres of unprotected fall edges exceeding the threshold.
Tanking lift pits, basement sumps, and water tanks during waterproofing meets confined space criteria with restricted entry and atmospheric hazard from solvents.
Solvent-based primers, LPG torches, and hot bitumen kettles introduce flammable atmospheres and ignition sources requiring formal hot work permit controls.
PCBU must prepare and consult workers on this SWMS before HRCW commences, retain it for two years post-incident, and produce on regulator request; penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
On a mid-rise apartment refurbishment, the waterproofing leading hand arrives at level six to prime and apply liquid polyurethane membrane to twelve ensuite floors and a shared podium balcony. At the 7am pre-start, the supervisor opens this SWMS on a tablet and walks the three-person crew through the hazard register. The crew identifies that today's primer is solvent-based — triggering the inhalation hazard line — and the supervisor cross-checks the SDS, confirms the A2P2 respirators have been fit-tested within the last twelve months, and starts the temporary extraction fans listed in the engineering controls before any drums are opened. The fall hazard line prompts inspection of the podium edge protection, where one guardrail stanchion is found loose; work on the podium is deferred until rectified, and the crew is redirected to the internal ensuites first. Each worker signs the SWMS register, noting respirator serial numbers. Two hours in, an apprentice reports a headache — the supervisor checks the VOC meter (reading above action level due to a wedged door), reopens ventilation, rotates the apprentice off solvent work per the administrative control, and annotates the SWMS field-change log. The document functions as a live operational record, not a filed-and-forgotten compliance artefact.
