How does leak detection in facades and cavity walls work?
The process of detecting facade and cavity wall leaks involves several steps and utilizes a wide range of tools and techniques suitable for every type of building. We use only advanced equipment such as endoscopy cameras, moisture meters, thermographic cameras, and ultrasound detection to pinpoint leak sources with millimeter precision. Thanks to our partnerships with suppliers like FLIR Systems and Tramex, we always work with reliable technology. Because we don't require demolition, your home remains intact.

- Infrared thermography: With thermal imaging cameras we visualize cold bridges, leakage traces and crack formation within the cavity wall.
- Endoscopic inspection: Using microscopic cameras, we investigate moisture sources and defects between the facade bricks and the underlying structure.
- Dye or tracer gas methodology: Using a harmless dye or a tracer gas mixture, we can see exactly where moisture is finding its way in.
- Humidity measurements: We use digital meters to map moisture values and distribution with pinpoint accuracy.

Types of facade and cavity wall leaks
There are various causes and types of facade and cavity wall leakage, each requiring its own impact and approach.
- Moisture penetration: Loose joints, porous bricks or inadequate facade insulation allow rainwater to penetrate inside.
- Capillary rising damp: Suction from the ground causes water to rise up into the wall. This often causes damage at the bottom of the facade.
- Cavity wall bridges: Construction errors or insulation material that completely fills the cavity can form bridges, allowing water to migrate in.
- Incorrect connections: Poor detailing in window frames, expansion joints or lintels can cause water infiltration.
