Application Method:

The application was carried out according to a modified version of Belzona System Leaflet FPA-1. The areas were cleaned and prepared to remove contamination and deteriorated concrete and to square up areas. Dust, dirt, and debris were vacuumed away. A 11/2” thick steel plate was bonded into place, using Belzona 1121. Stainless steel reinforcement was inserted into concrete vault walls, using Belzona 1121. Top side of steel plate was roughened. Belzona 4154 was mixed with clean, crushed granite and used to fill area to within 1 inch of the top of the repair area. The area was then conditioned with Belzona 4911 and top coated with 1" of Belzona 4131 to produce a finish that is smooth and level with the concrete substrate.

 
 

Belzona Facts:

Customer required minimal out of service timefram,and was looking for a long lasting, durable solution. Solution had to be Engineer certified. Solution had to handle weight of loaded dumpster trucks and roll-offs. Reasons Belzona was selected was attributed to the confidence in team based upon other previous application successes, ability to provide engineered solution, minimal downtime and right solution. Alternative technologies customer had in mind – welding and concrete pour, which did not meet downtime requirements and engineers were skeptical of concrete pour methodology.
