TESTIMONIALS

BAR BEACH

A major N.S.W. coastal apartment housing development suffering wall tie failure employed the services of A.G.M Construction Pty. Ltd, (02) 9644 3777, to install many thousands of remedial wall ties.
The Site Manager Mr Bill Hooper had used several types of ties and found the Thor Helical 9mm 316 Stainless Steel CDTies™ to have the least number of installation failures compared to other brands and technologies. As commented, all members of their remedial tie installation crew believe the Thor Helical 9mm CDTies™ to be superior and claim a preference for them especially now with the new lightweight CDTie™ setting tool that they have been using since mid-January. The “precise pitch”profile and the increased central core provide better tracking across cavities and allow successful installation into far harder bricks without bending. Their team have found other brands don`t track as well and have shown a tendency to miss the inner leaf hole and simply bend into the cavity.

Economically, savings have been made by greatly increased installation rates, less failed, wasted, bent ties, (and their removal costs), whilst using Thor Helical 9mm CDTies™. As with any remedial procedure the total installed costs, (material plus labour), are what count!
Thor Helical 9mm CDTies™ are accredited to carry the European Technical Approvals
identification mark.

BUNDOORA CAMPUS

Specification Description

Thor Helical 9.00mm nominal O.D., 316 grade stainless steel, helically roll – formed wire having a characteristic cross-sectional area of 14.88mm² and a pitch accuracy variation of no more than 0.5% from any given probate pitch along the axis.

Assessment of the Bundoora Campus of R.M.I.T. University 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 sections. During the works program an area built with a 300mm wall cavity was discovered and consideration was given to trial Thor Helical 9mm CDTies for this extremely wide cavity section. Using 450mm long impact driven Thor 9mm CDTies through the pre-drilled outer brick skin the 80+ ties were installed without any alignment failures at the R.M.I.T University Bundoora Campus, Victoria with thepre-drilled holes in the far-side inner leaf. The “precise pitch” manufacturing process provided accurate tracking across the cavity.

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