Torch-on waterproofing systems remain one of the most reliable and proven methods for protecting roofs, podiums, retaining walls, basements, balconies, and below-ground structures against water ingress and long-term structural damage.
Forspec Protective Coatings is expanding its waterproofing range with the release of the new FORZAFLEX torch-applied waterproofing system — a complete multi-layer APP modified bitumen membrane system engineered for Australian conditions.
The new FORZAFLEX system range includes:
- FORZAFLEX BASE 3mm
- FORZAFLEX MINERALE 4.5
- FORZAFLEX RR
- FORZAPRIME
Together, these products form a fully compatible torch-on waterproofing build-up designed for exposed roofs, podium slabs, planter boxes, retaining walls, basements, and critical waterproofing applications.
WHY TORCH-ON WATERPROOFING STILL LEADS THE INDUSTRY
Torch-applied APP modified bitumen systems continue to be widely specified across commercial and civil construction due to their:
- full bonded waterproofing performance,
- durability,
- puncture resistance,
- UV stability,
- and long-term waterproofing reliability.
Unlike liquid systems that rely heavily on film thickness consistency, torch-on membranes create a reinforced waterproof barrier with controlled membrane thickness and engineered multi-layer protection.
This makes them ideal for:
- roofs,
- balconies,
- podium slabs,
- planter boxes,
- retaining walls,
- basements,
- and high-risk waterproofing structures.
FORZAFLEX BASE 3MM
High-Performance Torch-On Base Waterproofing Membrane
FORZAFLEX BASE 3mm is a high-performance APP modified torch-applied membrane designed for use as a base layer or intermediate waterproofing layer in multi-layer membrane systems.
Manufactured with a high-strength non-woven polyester composite reinforcement, the membrane delivers:
- excellent tensile strength,
- dimensional stability,
- puncture resistance,
- and long-term waterproofing durability.
The thermofusible polyethylene film on both sides allows full torch bonding to prepared substrates and overlying membrane layers.
Ideal Applications
- Roof waterproofing systems
- Podium slabs
- Balconies & terraces
- Retaining walls
- Lift pits
- Wet basements
- Below-ground structures
Key Features
- APP modified bitumen technology
Reinforced polyester coreExcellent puncture resistance
- Fully torch bonded system
- High bond strength to concrete
- Suitable for Australian climatic conditions
Technical Highlights
- Thickness: 3.0mm
- Tensile Strength: ≥ 700 N / 50 mm
- Elongation at Break: ≥ 35%
- Watertightness: > 200 kPa
FORZAFLEX BASE 3mm is designed to be overlaid with a suitable cap sheet, screed, protection board, or finishing system and must not remain permanently UV exposed.
FORZAFLEX MINERALE 4.5
Heavy-Duty UV Stable Mineral Cap Sheet
FORZAFLEX MINERALE 4.5 is a heavy-duty UV stable mineral-finished torch-on membrane engineered for exposed waterproofing systems requiring long-term weather resistance and durability.
The membrane incorporates:
- APP modified bitumen,
- polyester reinforcement,
- and factory-applied mineral slate granules for permanent UV protection.
This makes it ideal for:
- exposed roofs,
- balconies,
- terraces,
- podium slabs,
- and above-ground waterproofing systems.
Key Benefits
- Permanent UV resistance
- Heavy-duty exposed membrane protection
- Mineral granule surface finish
- Excellent tensile strength
- Long-term durability
- Full torch bonded waterproofing
Typical Applications
- Exposed roof systems
- Podium slabs
- Balcony waterproofing
- Terrace waterproofing
- Retaining wall waterproofing
Technical Highlights
- UV Resistance: Pass
- Tensile Strength: ≥ 740 N / 50 mm
- Field Seam Strength: ≥ 1.2 kN/m
- Elongation at Break: ≥ 35%
The mineral surface provides permanent UV stability while maintaining high waterproofing performance across harsh Australian weather conditions.
FORZAFLEX RR
Root-Resistant Torch-On Waterproofing Membrane
FORZAFLEX RR is an advanced root-resistant APP modified torch-on membrane specifically engineered for:
- planter boxes,
- landscaped podiums,
- green roofs,
- and retaining structures exposed to aggressive vegetation and root penetration.
The membrane incorporates specialised anti-root additive technology designed to resist biological attack and root penetration through the waterproofing layer.
Ideal Applications
- Planter boxes
- Green roof systems
- Landscaped podiums
- Plaza decks
- Retaining walls adjacent to vegetation
- Below-ground root-resistant structures
Key Features
- Anti-root additive technology
- Root penetration resistance
- APP modified membrane system
- High puncture resistance
- Flexible waterproofing performance
- Engineered for protected systems
Technical Highlights
- Thickness: ~4.0 mm
- Tensile Strength: ≥ 740 N / 50 mm
- Root Resistance: Pass
- Watertightness: > 200 kPa
FORZAFLEX RR replaces standard cap sheets where root-resistant waterproofing protection is required.
FORZAPRIME
High-Performance Bituminous Primer
FORZAPRIME is a high-performance solvent-based bituminous primer designed to improve adhesion between substrates and torch-applied membranes.
Manufactured with modified bitumen and adhesion-enhancing additives, FORZAPRIME promotes strong and uniform membrane bonding across:
- concrete,
- masonry,
- and metal substrates.
Main Functions
- Seals porous substrates
- Binds surface dust and fines
- Improves membrane adhesion
- Enhances torch-on system performance
Typical Applications
- Roof slabs
- Podium slabs
- Balconies
- Retaining walls
- Foundations
- Lift pits
- Metal substrates
Application Methods
- Brush
- Roller
- Low-pressure spray equipment
Technical Highlights
- Coverage: 4–6 m² per litre
- Drying Time: Approximately 1 hour
- Solids by Weight: ~35%
FORZAPRIME forms the critical bond layer between the substrate and torch-applied membrane system.
COMPLETE FORZAFLEX SYSTEM BENEFITS
The FORZAFLEX system has been engineered as a compatible multi-layer waterproofing build-up rather than individual standalone products.
System Advantages
Torch-applied fully bonded waterproofing systems
- UV resistant exposed membrane systems
- Root-resistant waterproofing systems
- High puncture resistance
- Multi-layer compatible build-ups
- Excellent seam fusion performance
- Designed for Australian conditions
- Suitable for below-ground and exposed applications
IDEAL FOR
The FORZAFLEX system range is suitable for:
- Roof waterproofing
- Podium slabs
- Balcony systems
- Retaining walls
- Basements
- Lift pits
- Green roofs
- Planter boxes
- Plaza decks
- Commercial waterproofing structures
WHY SYSTEM COMPATIBILITY MATTERS
Waterproofing failures often occur because incompatible products are combined together.
The FORZAFLEX range was developed as a fully compatible torch-on system where:
- primers,
- base membranes,
- cap sheets,
- and root-resistant layers
are designed to work together as one engineered waterproofing structure.
This improves:
- bond performance,
- seam integrity,
- waterproofing continuity,
- and long-term system durability.
