Belzona Facts:

The old expansion joints were not flexible enough and were allowing rainwater to seep through into the neighboring dwellings causing damp problems. The joints were removed and filled using Belzona® 4521 for the horizontal joints and Belzona® 2211 for the vertical. A layer of Belzona® 2211 was also applied over the horizontal joints to improve the aesthetics of the repair.
