16,000 cartridges of Bostik Xtreme Fix in the Legacy Way Tunnel

Bostik has provided a superior bonding solution to the complex and demanding needs of the Legacy Way Tunnel Project in Queensland. The project required a reliable, high-quality, economical product that cured under reasonable time frames. Bostik Xtreme Fix was selected due to its high performance qualities in combination with factors such as economy and Bostik’s local presence.

The Legacy Way Tunnel stretches around 4.6 km connecting the Western Freeway at Toowong with the Inner City Bypass at Kelvin Grove. The project consisted of an integrated team of 3 principals: BMD Constructions, Ghella, and Acciona.

The tunnel was fabricated using two tunnel boring machines (TBM’s) that were 12.4 m in diameter and 110 m in length. The tunnel ring was placed as the TBM’s progressed. Each ring consisted of a 9 precast elements; the perimeter of each had an EPDM gasket bonded with sealant. More than 4,300 rings and a total of 120,000 m3 of concrete were used.

After trialling a range of products, the client saw Bostik Xtreme Fix as best suited to the project. ‘We trialled two adhesives prior to receiving Bostik Xtreme Fix,’ stated lead engineer Ignacio Sanz ‘Bostik Xtreme was by far the best. There is no special respiratory equipment required during use, does not attack the EPDM, and cures dry. It’s the best adhesive for this job.’

Bostik Xtreme Fix is a high performance grab adhesive that grabs instantly to most surfaces. Some of its superior features are:

  • High strength.
  • Permanent flexible bond.
  • Low VOC.
  • Environmentally friendly.

In total, the EPDM gasket was bonded using 16,000 Bostik Xtreme Fix cartridges.

Local R&D teams are constantly working to ensure products are world class and still relevant to the Australian context.

Clearly evident in this project, Bostik has the capacity to supply high quality products to large, demanding projects.
