• Sector: Confectionery Company
• Project: Waterproofing of industrial roof with Polyurea STARFLEX HR-S
• Substrate: bituminous membranes and pvc
WHO IS THE COMPANY?
The customer has long (more than 60 years) been known for excellent service and attention to detail. It is a prestigious international confectionery industry that works in Italy with two production plants. Thanks to its manufacturing and sales know-how, it works today in the USA, all EU countries, Turkey, Russia, China, Hong Kong and Australia.
WHAT WERE THE PROBLEMS?
In Italy, the project was carried out in San Giuliano Milanese production plant.
The problems on the roof of the production plant were: water infiltration, due to the presence of several layers of bituminous membranes and PVC applied over the years and now in the process of detachment. The existing coating was subjected to widespread reptation and the presence of numerous plants didn’t guarantee the resistance of the existing coating.
The technical solution proposed by mpm was the realization of a waterproofing system, specific for the rehabilitation of existing coating that had a thickness of 3 millimeters.
Mpm, together with its partner company, has created a totally seamless coating using the STARFLEX ON system, based on polyurea, sprayed directly over the existing one.
First of all, the system involves the substrate preparation, in order to ensure a stable and clean substrate, because there were numerous discontinuities. Subsequently, the membranes in detachment were removed.
After the substrate preparation, it was necessary to apply a high adhesion primer DUROGLASS FF4416 in order to guarantee the correct adhesion to the existing substrate.
Subsequently, STARFLEX HR-S, a pure polyurea spray-applied membrane was used.
Finally, the POLISTAR E/P aliphatic polyurethane top coat was applied.
Top coat in white colour allows to have a high solar reflection, protection against UV rays and improvement of the internal and external temperatures of the roof.
The mpm work, through the inspection of one of our specialized technicians, allows to identify the problems and to solve them definitively without removing the existing one, thus reducing time and work costs.
THE APPLIED SYSTEM
The system includes the following products:
– PRIMER: DUROGLASS FF4416
– WATERPROOFING MEMBRANE: STARFLEX HR-S
– TOP COAT: POLISTAR E/P
