Masonry Wall Reinforcement Blast Loading Upgrade
Rhino Carbon Fiber was contacted by the restoration contractor, who was responsible for repairing a chemical processing facility, after a catastrophic explosion and the resulting fire. As repairs were made, all of the walls had to be upgraded to handle the blast loads specified by the consultant designing the repairs. This included reinforcing two sides of a three-story stairwell, as well as several other walls in the building. The main reason the reinforcement was needed was to protect individuals and system components in these areas if there happened to be another explosion.
The restoration contractor was on a tight schedule to complete the repairs and get the facility operating again. Upon contacting Rhino, a representative was on the project the same day to investigate the application and start working on the possible solutions. Uzman Engineering out of Malvern, PA put together the structural design to meet the requirements of the project.
As the design was being completed, Rhino worked with the restoration contractor and the consultant to investigate the surface preparation requirements. Upon completing on-site bond testing in multiple areas within the structure, it was determined that portions of the existing coating could remain and that the CFRP could be bonded directly to the roughened surface coating. In other areas, the bonds failed prematurely or between layers in the coating so the coating had to be removed.
Rhino was also able to coordinate the work that was necessary with one of their own contractors. This contractor was not only able to meet the tight project deadlines but also worked around several other contractors performing various tasks to restore the facility. Another major benefit of using Rhino’s products is that all of the materials were able to be shipped right away. When dealing with these types of projects, having to wait for inventory to arrive in order to fulfill the needs of a project is not an option.
By using Rhino Carbon Fiber’s reinforcement products, the General Contractor was able to meet the needs of the project while staying on schedule and on budget.
