Sealing and repair
Balcony and terrace refurbishment
With a leaking balcony the visible surface is rarely the problem. Water that gets in through cracks, open joints or a missing edge detail travels into the screed and on into the concrete slab. There it attacks the reinforcement, and a blemish becomes structural damage. So it is not the surface that decides the service life but the waterproofing beneath it – and that stays invisible afterwards.

services offered by the practice
Sealing, building up, surfacing – so that no more water gets into the structure.
Typical occasions
Wann diese Untersuchung sinnvoll ist
- Damp patches on the balcony soffit or on the ceiling of the room below
- Spalling concrete, exposed reinforcement at the balcony edge
- Cracks, hollow-sounding tiles, open or washed-out joints
- Water standing on the surface instead of running off
- The junction with the door sits too low, or was never formed
Methods used
Womit wir am Bauwerk arbeiten
- Survey of the existing build-up and moisture measurement in the screed
- Removal down to a sound substrate, inspection of the concrete slab
- Forming a fall so that water runs safely to the edge
- Waterproofing in liquid-applied membrane – seamless, including around balustrade posts and outlets
- Proper formation of the edge detail, the door junction and the drainage
- Surface to choice: stone carpet, tiles or a coating
What you receive
Das erhalten Sie
- A closed waterproofing layer that is tight at the penetrations too
- A fall that takes water away from the building
- Documentation of the build-up with photographs of every layer
