Causes
Causes of leaking flat roof membranes
- ▸Damage to the waterproofing membrane due to structural or environmental influences
- ▸Inadequate drainage systems
- ▸Faulty planning and execution
- ▸Incorrect positioning of insulation and vapor barrier
- ▸Condensation moisture due to lack of ventilation
- ▸Deformation and cracks due to thermal stress
- ▸Unsuitable materials during initial waterproofing
Consequences
Consequences of flat roof leaks
- ▸Water penetrates the insulation layer and leads to permanent moisture
- ▸Thermal insulation properties of the insulation layer are lost
- ▸Rising heating and cooling costs due to poor thermal insulation performance
- ▸Increased risk of mold on ceilings and walls
- ▸Summer vapor pressure can damage the waterproofing again
Economic advantage
Modern detection technology from DÖLCO makes insulation layer drying significantly more economical than a complete renewal of the roof waterproofing.
Methods
Solutions for damage minimization
Depending on the roof construction, accessibility, and extent of damage, DÖLCO uses various detection methods -- always with the goal of finding the leak precisely and quickly.
💨
Smoke gas method
Smoke is introduced under the roof waterproofing. Smoke visibly escapes at the leak site -- precise and fast.
🔊
Electro-acoustics
Electrical impulses generate an acoustic signal at the leak. Highly sensitive equipment locates the damage site exactly.
🧪
Tracer gas method
Tracer gas is injected under the waterproofing. A sensor detects escaping gas -- even on hard-to-reach roofs.
💧
Moisture measurement
Determination of the extent of damage in the insulation layer. Basis for the economic decision: Dry or restore?
