Roof gardens

cubierta ajardinada

Rooftop systems are a very useful systems that wear the top of the buildings and provide multiple actions such as absorbing rainwater, providing insulation, creating an habitat for wildlife and decreasing stress of the people, providing a more aesthetically pleasing landscape, and helping to lower urban air temperatures and mitigate the heat island effect.

All the concrete structures need to be protected from the rainwater, of course. In this case, using vegetation as a “ green natural finishing”, its need to be protected from the irrigation water too.

TECNOCOAT and DESMOPOL, creates a seamless, continuous skin all over the concrete element protecting it and avoiding the risk of leaks or roots penetration.

Furthermore, this polyurethane membrane, is perfectly water highness, waterproof, ponding water work and supporting the weight of the plantation soil. These systems are approved by EOTA y BBA according European norms.

3. Waterproofing membrane

Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.

4. Finish layer

The company responsible for the design and style of the gardened roof area will need to decide on the various additional coats required for this type of finish.
