ThorHelical 9mm Drive Ties for consistent quality masonry

Assessment of the R.M.I.T. University Bundoora Campus by Mr. Chris Drzewucki of Meinhardt Facades revealed a requirement for the installation of remedial brick ties.

The installation was performed in stages and the initial product used was the 8mm Helifix DryFix Remedial wall tie system on the first two sessions. During the works program an area built with a 300mm cavity was discovered and consideration was given to trial Thor Helical 9mm Drive Ties for this very wide cavity section. Using 450mm long 9mm Thor ties impact driven through the pre-drilled outer brick skin the 80+ ties were installed without any alignment failures to the pre-drilled holes in the far-side leaf. The "precise pitch" manufacturing process resulted in accurate tracking across the cavity.

The third installation session comprised the usage of the existing 8mm Helifix DryFix Remedial wall tie stocks and the balance using Thor Helical 9mm Drive Ties... The site supervisor, Mr. Joe Spagnolo of Vertitech Australia Pty. Ltd., commented that the improved 2nd generation profile of Thor Helical resulted in a dramatic reduction in wastage compared to the previous product. Time saved by not having to extract bent, deformed ties, also improved installation times and costs.
