The following is a special excerpt of a feature article by GluDown President Chad Bruce published by the Tilt-Up Concrete Association.

It is fair to say that the OSHA 1926.1153 ruling that went into effect in September of 2017 has had a tremendous impact on the construction industry as a whole.

During the annual TCA Convention in Miami, we spoke with several contractors who understood the impact this regulation would have on their current drilling and nailing process.

As part of these conversations, we recognized a need for a best practices guide related to how to use adhesives in the forming process. Here is a quick overview of the guide, highlighting the stages and topics discussed, as well as some wise words from experienced professionals within the industry and a video demonstrating tilt-up forming material spacing. To view the detailed guide with images, be sure to check out the full article on Tilt-Up Today.


Materials

“If you don’t use moisture resistant or treated materials on a job you are gluing, you are asking for trouble.” Russell Frank – CMC Construction Services Dallas, TX
