WHO IS THE COMPANY?
The customer is an important company specializing in the import, roasting and marketing of coffee in Europe and worldwide. All the lots are stored in the owned factory, the roasting and packaging of the finished products for their subsequent distribution, also carried out with own means.
In Switzerland, the factory owned production where the intervention was performed, is located in Mendrisio.
The factory owned showed several problems of water infiltration on the roof due to the presence of an old PVC membrane, in danger of rectification phenomena and now being detached. The presence of installations and the complex geometry in some areas no longer guaranteed the tightness of the existing coating.
For the restoration and protection of the existing roof, Mpm together with its partner company has studied and supplied a totally seamless coat through the use of the STARFLEX ON system, based on polyurea and applied by spray directly on the existing one. The work avoided the use of flames with a seamless solution and with high elasticity (up to 550% in terms of elongation at break). The system has a special liquid-sprayed membrane which, once applied, forms a seamless waterproofing coating, horizontally and vertically, without joints and points of discontinuity, without the need for demolition and restructuring, able to adapt to different geometries and materials . The first phase consisted of the application of a specific primer for PVC, two-component epoxy, DUROGLASS FF4416, in order to guarantee the perfect adhesion.
Subsequently, a waterproofing coating was applied through the use of polyurea soft STARFLEX HR-S, free of plasticizers and solvents. The installation took place through high pressure bi-mixer spray system. The spray installation of the mpm polyurea allows to waterproof also the part of roofs where there are points of discontinuity and complex geometries, such as skylights, parapets and installations, treating even the most difficult and hidden points, and creating a seamless surface
In the end, we proceed with a UV- resistant highly reflective polyurethane finish in white color, in order to avoid yellowing problems with temperature reduction function, POLISTAR E/P.
Through the inspection of one of our specialized technicians, the work of Mpm has made it possible to select the existing problems and to intervene, together with our applicator partner, to definitively resolve what has been tackled without removing the existing one and reducing working times and costs.
The system presents the following products:
