- Substrate: different substrates
WHO IS THE COMPANY?
The customer is a modern company, specialized in meat processing and in the low temperature storage for third parties. It can offer to its clients a huge complex used for low temperature storage with a capacity of about 8.000/10.000 tons. The many years of experience acquired is a guarantee of reliability for its own customers, and for the HACCP implemented system.
The production plant where the work was carried out is located in the province of Milan. The main problems where due to water infiltrations spread on the roof, following the presence of different substrates such as PVC, bituminous membranes and concrete. They were subject to reptation and wore phenomena, not admissible in food environments.
The presence of plants in some areas has determined the discontinuity of the existing coat, no longer guaranteeing waterproofing.
For the restoration and protection of the existing roof, mpm, together with its partner company, studied and provided a totally seamless coat through the use of the STARFLEX ON system, polyurea based, sprayed on the existing one. The work avoided the use of flames, adopting a solution with high elasticity (until 550% in terms of break elongation) able to bridge joints and cracks.
The system provides a special sprayed liquid membrane which, once applied, forms a seamless horizontal and vertical waterproofing roof, without joints and discontinuity points, without the need for demolitions and renovations, able to adapt to different geometries and different materials.
The first phase, after a correct cleaning and arrangement of the existing one, consisted in the application of specific primers for different substrates.
- For the PVC membrane a two component epoxy primer DUROGLASS FF4416, extremely versatile and without drastic time limits;
- for the bituminous membrane, PRIMER 0230, one-component polyurethane with rapid adhesion
- for the concrete substrate DUROGLASS P2 PRIMER, a special epoxy adhesion promoter with high mechanical features,
Subsequently, a waterproofing system was applied using soft pure polyurea STARFLEX HR-S, free of plasticizers and solvents. The installation took place by means of a high pressure bi-mixer spray system.
The spray installation of the mpm polyurea allows to waterproof even the roofs where there are discontinuity points and complex geometries, such as skylights, parapets and plants, thus treating even the most difficult and hidden points, and creating a seamless surface without joints.
mpm’s system provides the following products:
- PVC PRIMER: DUROGLASS FF4416
- BITUMINOUS MEMBRANE PRIMER: PRIMER 0230
- CLS PRIMER: DUROGLASS P2 PRIMER
- WATERPROOFING: STARFLEX HR-S
mpm’s work, through the involvement of our technical specialized office, has allowed us to recognize the problems and to intervene, together with our applicator partner, offering a quick, certified and long-lasting result.
