Gluing Down: Best Practices

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. To view the detailed guide with images, be sure to check out the full article on Tilt-Up Today.
