Application Situation
The treatment plant operates several Aeration Basins so they were able to de-water the basin for a sufficient period of time to enable joint preparation, renewal and cure.
Application Method
The application was carried out in accordance with Belzona Know-How System Leaflet FPA-6. A foam backer rod was inserted to expansion joint the proper depth. Belzona 2911 was used to condition the surface area and Belzona 2111 was hand applied to seal the expansion joint.
Belzona Facts
The client had previous experiences with the quality of pump and concrete repairs so they decided to apply the same logic when choosing the material to secure their expansion joint. They did not want to come back and redo this job prematurely - hence the choice for Belzona.
