TORCH-ON WATERPROOFING
Torch-on waterproofing uses reinforced APP-modified bitumen membranes that are heat-fused to a properly prepared surface to form a continuous, flexible waterproofing layer. The system is suited to flat roofs on commercial, industrial and residential properties, providing a robust waterproofing solution where correct surface preparation, drainage, laps, joints and detailing are critical to long-term performance.
Drytek undertakes torch-on waterproofing projects ranging from individual buildings to larger commercial and industrial developments, including flat roofs, retaining walls and other concrete structures. We assess the existing surface condition, identify the required preparation and repairs, and install the system with particular attention to parapets, outlets, penetrations and other critical details.
Drytek provides torch-on waterproofing for developers, architects, main contractors and property owners across new construction, refurbishment and re-waterproofing projects.
COMMON PROBLEMS
These are the most common ways flat roof waterproofing fails. Recognising the signs early can mean the difference between a straightforward repair and a full re-waterproof.
Poor falls or inadequate drainage can leave water sitting on the roof surface for hours or days after rain. This adds constant pressure on the waterproofing layer and creates pathways for water ingress that get worse over time.
Ageing membranes and coatings can crack, blister or split as they reach the end of their service life. Once this happens, they gradually lose their ability to keep water out, allowing moisture to reach the structure below.
Parapets, wall junctions, outlets and expansion joints are common failure points on any flat roof. Once the detailing around them deteriorates, these areas become a direct route for water to enter the building.
Cracks and porous areas in exposed concrete give water a direct way to penetrate the surface. Left unaddressed, this leads to dampness, staining and structural damage below, often before it's visible from above.
TORCH-ON APPLICATIONS
Torch-on systems can be used across a range of waterproofing applications, from residential flat roofs to larger commercial surfaces and below-ground areas.
Torch-on membrane systems provide a durable, long-lasting waterproofing solution for flat roofs. Proper surface preparation is essential to performance, and our team handles this as standard on every installation.
Deteriorated waterproofing doesn't always mean a full roof replacement. Once we've assessed the surface, re-waterproofing restores protection and extends the roof's remaining lifespan.
Torch-on systems scale to larger commercial and industrial surfaces, including parking decks and exposed concrete structures. We work around site access and operating hours where needed.
Torch-on membrane isn't limited to flat roofs. It's also effective for below-ground and vertical applications like foundation walls. Suitability is confirmed on site before work begins.
