Torch-on bitumen modified sheet membranes
Technical product reference for torch-applied SBS and APP modified bitumen sheet membranes used in balcony, terrace, podium, and flat roof waterproofing. Covers system classification, base and cap sheet selection, brand comparisons, and key application requirements for Australian Class 2 strata buildings.
What are torch-on bitumen modified sheet membranes?
Torch-on modified bitumen sheet membranes are factory-manufactured waterproofing sheets composed of a bitumen binder modified with either SBS (styrene-butadiene-styrene, an elastomeric rubber modifier) or APP (atactic polypropylene, a plastomeric modifier), reinforced with polyester or fibreglass carrier, and applied by gas torch to create a fully-bonded waterproof membrane layer. They are a well-established system for balcony, terrace, podium slab, and flat roof waterproofing in Australian remedial building practice. A two-layer system — base sheet plus cap sheet — is standard for balcony remediation on Class 2 strata buildings. The mineral granule-surfaced cap sheet provides a UV-stable, exposed or lightly trafficable finished surface where tiles or screed are not required.

Soprema Sopralene Flam 180 AR
SBS modified bitumen — torch-on base sheet
SBS elastomeric modified bitumen — polyester-reinforced torch-on base sheet
System Description
Sopralene Flam 180 AR is Soprema's SBS (styrene-butadiene-styrene) elastomeric modified bitumen torch-on base sheet, polyester-reinforced, with anti-root properties for balcony, terrace, and podium applications. It is the base/underlay layer in a two-layer torch-on system — not a finished surface on its own. Applied by gas torch to a correctly primed and prepared concrete substrate, the sheet is fully bonded at laps with minimum 100 mm side and 150 mm end lap seals. A Soprema-approved cap sheet (Sopralene Flam 250 or equivalent) is applied over the base sheet to complete the two-layer system. Lap seam integrity and corner detailing are the primary quality hold points in torch-on application.
Technical Properties
- SBS elastomeric modifier — higher elongation and cold weather flexibility than APP-modified systems
- Polyester reinforcement — good dimensional stability and tear resistance under torch application
- Anti-root formulation — suitable for podium, planter box, and balcony applications where root resistance is specified
- Factory-manufactured sheet — consistent thickness and composition across the entire roll
- Suitable for two-layer torch-on systems on concrete balconies, terraces, and podium slabs
Limitations
- Base sheet only — must be overlaid with a compatible cap sheet — do not leave as the exposed surface
- Requires licensed gas torch applicator — torch-on application is not suitable for unlicensed or inexperienced operators
- Fire watch required during and after torch application on occupied buildings — confirm fire management requirements with the principal
- Primer mandatory on all concrete substrates — confirm Soprema-compatible primer with technical representative
- Lap seam quality is the primary failure mode — all laps must be correctly heated, bonded, and inspected during application

SBS vs APP, and base sheet vs cap sheet
SBS vs APP modified bitumen
- SBS (elastomeric) — rubber-modified — higher elongation and flexibility — better cold-weather performance — the dominant specification in Australian balcony and residential waterproofing
- APP (plastomeric) — plastic-modified — harder, more rigid — better UV and heat resistance in some formulations — commonly used in hot climates and flat roof applications
- For most Australian strata balcony remediation, SBS is the standard specification — confirm the required formulation with the principal or waterproofing consultant
Base sheet + cap sheet — two-layer system
- Base sheet — applied directly to the primed substrate — provides the primary waterproofing layer and the bonded interface with the concrete
- Cap sheet — applied over the base sheet — provides UV protection, surface finish, and the final weatherproof layer — mineral-faced cap sheets can be left exposed
- Two-layer systems provide redundancy at lap seams — the most robust specification for Class 2 balcony remediation
- Single-layer systems may be permitted in some applications — confirm against the project specification before substituting
Fire safety and applicator licensing — mandatory requirements
- Torch-on application requires a licensed gas torch waterproofing applicator — this is not a system that can be applied by an unlicensed contractor
- A fire watch is mandatory during and after torch application — an approved fire extinguisher and fire watch person must be present throughout application
- On occupied strata buildings, a fire management plan must be prepared and approved before commencement — the principal, building manager, and fire authority must be notified where required
- Torch application must not occur adjacent to flammable materials, combustible substrates, gas lines, or penetrations without specific fire protection measures in place
- Do not specify torch-on systems in locations where naked flame is prohibited by building management, strata by-laws, or fire safety orders without confirming compliance first
- A hot works permit may be required for application in strata buildings — confirm with building management and the principal before scheduling application
