Белзона Факты
Belzona solution has a long successful history providing long term performance. After 5 years in service, Belzona® 4521 application was reviewed and showed no signs of leakage after several hours of hard rain. An intentional pinhole was added during installation to test failure resistance. Pinhole also remained unchanged after 5 years. A conventional silicone joint material installed on the other part of the bridge began leaking within 12 months of being placed.
