Torch-On Waterproofing Services in Gauteng
Durable Flat Roof Protection for Residential, Commercial & Industrial Properties
At RR Roof Waterproofing, we specialize in high-performance torch-on waterproofing systems built to endure South Africa’s toughest weather conditions. Whether it’s a residential garage slab, a commercial rooftop, or an industrial deck, our torch-on applications provide a seamless, long-lasting moisture barrier with up to 10–15 years of protection.
We proudly serve homeowners, property developers, commercial managers, and industrial site operators across Gauteng, ensuring total protection against leaks, damp, and long-term structural damage.
What Is Torch-On Waterproofing?
Torch-on waterproofing involves the application of a modified bitumen membrane, that is heat-bonded to a surface using a blowtorch. Once sealed, the membrane creates a tough, elastic, and UV-resistant surface that protects flat or low-slope roofs from water penetration.
It’s the industry gold standard for flat roofing and slab applications — thanks to its durability, flexibility, and superior sealing performance.
Residential Torch-On Waterproofing
While traditionally used on commercial or industrial buildings, torch-on systems are ideal for residential applications too — especially for homes with flat concrete slabs, garages, balconies, or roof decks.
Applications:
- House and garage flat roofs
- Parapet walls and boundary walls
- Roof-top patios
- Balconies and terraces
- Waterproofing above living spaces (e.g., slab over kitchen/lounge)
Commercial Torch-On Waterproofing
Office parks, retail centers, schools, and mixed-use buildings often feature concrete roofing systems vulnerable to water pooling and expansion damage. We install robust, torch-on systems designed to handle heavy traffic, mechanical installations, and seasonal rainfall.
Used For:
- Shopping centre rooftops
- Educational institutions and clinics
- Corporate complexes
- Apartment building roof decks
Industrial Torch-On Waterproofing
Industrial properties face some of the harshest roof conditions. With vast surfaces, high foot traffic, chemical exposure, and equipment installations — torch-on is the best defense.
Common Installations:
- Factory and warehouse roofing
- Manufacturing plant slabs
- Logistics and storage facility rooftops
- Maintenance walkways or deck platforms
The RR Torch-On Process
Roof Inspection & Quotation: We assess your slab, surface type, pitch, drainage, and existing damage.
Surface Preparation: Cleaning, crack sealing, and priming are done to ensure maximum adhesion.
Primer Application: We apply bitumen primer for bonding strength.
Torch-On Membrane Application: Using high-heat gas torches, we lay and seal the membrane with overlaps and proper detailing.
Detailing & Finishing: Corners, outlets, and joints are reinforced with bitumen and sealant.
Inspection & Guarantee: A full inspection with a written 10 year guarantee.
Why Torch-On Beats Other Waterproofing Systems
- Highly Durable – Lasts over a decade with minimal maintenance
- UV Resistant – Mineral-surfaced versions reflect sunlight and reduce heat buildup
- 100% Waterproof – Seamless membrane prevents even microscopic leaks
- Structural Flexibility – Can expand/contract without tearing
- Versatile – Works on slabs, parapets, planters, and below-ground areas
Why Poor Torch-On Installation Fails
Many so-called professionals cut corners with cheap membranes, poor surface prep, or low-quality torches. This results in:
- Blistering or bubbling
- Lifted corners and overlaps
- Early membrane cracking
- Ponding and internal leaks
