Control joints on concrete structures are crucial for expansion and contraction; however, over time, the flexible sealant fails due to various reasons such as weather, age, salt, wind, etc. TMI Coatings, Inc. (TMI) was hired by a farmer and rancher-owned cooperative, Cenex Harvest States (CHS), to complete over 17,000 linear feet of joint sealant repair, consisting of removal and replacement at one of their facilities in Louisiana. The joint sealant had failed, triggering water intrusion into the concrete buildings, and causing water damage. With help from the CHS, TMI devised a plan to rig the building safely and complete sealant repair work in a quality manner.
- On two separate concrete buildings, TMI utilized specialized rigging to access 100% of the buildings that were 120’ to 180’ in the air.
- TMI removed failed sealant and backer by routing out the joints on all horizontal and vertical joints. The joints were then cleaned to remove foreign debris and other contaminants.
- A new closed-cell backer rod was installed where the old backer rod was removed.
- Lastly, an elastomeric polyurethane sealant was installed, which allows excellent flexibility as the weather changes with the seasons.
TMI was able to complete over 17,000 linear feet of sealant repairs safely. The safety manager onsite complimented the crew on always following their rules while working onsite. And the Director of Terminal Operations said the quality of TMI’s work is a 9/10. Countless Happy Customers.
