Belzona 2211 was applied to seal the joint. To further seal and encapsulate the joint, bridging tape was applied over the expansion joint prior to the application of the Belzona 3111 system.This also provided an aesthetically pleasing finish.


Belzona Facts:

Belzona 4141 provides a durable joint nosing, whilst Belzona 2211 provides a highly elastic long-term waterproof seal in the joint. The Client ordered two more expansion joint repairs after this one.
