If the balcony waterproofing has not been properly installed or is already older, liquid can penetrate the building material through small cracks and expand during frost.
Our approach to the renovation of balconies
The cause: moisture penetration
Balcony and terrace coatings are exposed to extreme weather conditions, which can lead to cracks and other imperfections appearing on the surfaces and in the seals. Possible consequences of this are additional surface damage and humidity penetrating the building. Renovation is therefore urgently recommended to prevent further damage.
01 Preparing the renovation
For the renovation job we first remove the surface covering (like the tiles or slabs) and the existing seal, until we reach the load-bearing substructure. If necessary we create a new, slightly inclined surface. We then add an initial primer to the adhesive surface.
02 Sealing the balconies
First, details such as the door connection as well as the wall connection with reinforcing fleece insert are sealed object-specifically using ISOTEC liquid plastic or ISOTEC combiflex waterproofing. Then the surface of the balcony or terrace is finished with the respective waterproofing material.
03 Surface protection of the balconies
In order to protect a previously sealed balcony or terrace, we will apply a protective and wear layer depending on the customer's wishes and the needs of the building. This can consist of a thin layer of marble or quartz gravel, a coating of coloured chips or a superstructure made up of tiles or wood.
For our ISOTEC’s Balcony Renovation we use a system specially developed for this purpose, which thanks to its excellent adhesion to the ground and high crack bridging, is resistant to the extreme weather conditions that balconies and terraces can be exposed to. Depending on the customer’s usage requirements and wishes, we provide various protective layers, ranging in thickness from 4 to 10 mm, for the surface design of a previously sealed balcony or terrace surface.
In order to achieve a successful renovation special attention needs to be given to the details. We have developed solutions for all the adjoining areas found in a balcony renovation, such as window elements, railing posts or drainage channels.
Extensively tested - ecologically certified. The products used in the ISOTEC Balcony Renovation are certified, odourless and free of environmentally harmful substances.
Before and after comparison
- Thin-layer coating system
- Reliable renovation success
- Tested materials
- Increase in value of the property
- No excavation of the existing floor

This always depends on the type of renovation. If only the flooring is removed and redone, it can take 1 to 2 days. If the balcony is completely renovated, it can take over a week.
