Our Challenge: Waterproofing a Roof in Winter with a Temperature of 2 Degrees Celsius and 93% Humidity
Application of Waterproofing systems made out of Polyurethane-reinforced polymethyl methacrylates
In this example, we will show how an 85m² large rooftop terrace can be waterproofed in winter.
First, the mixing area is prepared and the reinforcing mesh is cut to size.
Here, the systemic primer of the surface can be recognized as a dark strip.
Additionally, penetrations of the roof are boarded up if working on them directly is not necessary.
At 11:32 AM the waterproofing work begins.
For this project, reinforcing mesh is placed on vertical surfaces while still wet. (Wet-on-wet technique)
It is also of note that the used waterproofing system is well-suited for wood, concrete and plaster bases, as well as metal and bitumen.
At 11:40 AM the surface waterproofing begins.
Like before, the surface reinforcement is applied “wet-on-wet”.
To keep the application time under 20 minutes, a second team starts working. This way no compound failure can occur with hardened material.
The third reinforcement track is installed at 11:57 AM. At the same time, edge finishes are being prepared in time for the next track.
Soon the 4. and 5. Reinforcement tracks are already being worked on.
At 12:37 AM the majority of the roof has already been waterproofed.
The last tracks are installed in opposite direction.
The waterproofing is complete at 13:30 AM.
Within two hours, an 85m² roof is waterproofed, can be used 30 minutes later, and all with better technical values than most roof sheetings.
