Triflex Roof Refurbishment over Bitumen Membrane in Italy

BRIXEN/ITALY, July 31, 2017 – Brixen Primary School in South Tyrol had plans to install photovoltaics on its flat roof, but first the roof waterproofing needed refurbishment. Triflex, a German-based company for construction chemicals, provided the solution: Triflex ProTect, a waterproofing system developed for flat roofs. The liquid applied waterproofing could be applied over the existing bitumen membrane, which spared the school the expense of replacing it.

The roof waterproofing of Brixen Primary School in northern Italy had to be redone in order to install photovoltaics. The existing bitumen sheeting was already 12 years old and quite damaged.
One condition when carrying out the task was that the refurbishment work had to have a minimum effect on the running of the school. This ruled out the removal of the existing bitumen roof membrane, as it would have been hugely time-consuming and expensive.
Furthermore, it had to be possible to complete the work quickly, as not much time was available: the deadline for installation of the photovoltaics had to be met in order to receive a state grant. This meant both roof refurbishment and photovoltaic installation had to be completed by the deadline. The time frame was around four weeks.

Brixen Primary School had plans to install photovoltaics on its flat roof. For this purpose contractors waterproofed the surface with Triflex ProDetail and Triflex ProTect.

Triflex provided the solution: the liquid applied waterproofing could be applied over the existing bitumen membrane, which spared the school the expense of removing and replacing it. Adhering to the deadline was not a problem because the system proved to be quick and easy to apply.

First, the contractors cleaned the bituminous surface and then waterproofed the many roof penetrations and wall junctions with Triflex ProDetail. The existing bitumen membrane did not have to be primed.
In the next and final step, the surface was waterproofed with Triflex ProTect, a waterproofing system specially developed for flat roofs.
Thanks to Triflex ProDrain and Triflex ProTect, the roof is now protected against penetrating moisture details are integrated into the surface. bi
