LEGACY WAY TUNNEL
DEEP CRACK INJECTION

Our CHEMRITE® CILV was selected to be used in the Brisbane's Legacy Way Tunnel to repair cracks in a 28 meter long post-tensioned beam. CHEMRITE® CILV is a flowable crack repair system specifically formulated to achieve high strength, whist still maintaining a good pot life at a very low viscosity.

 

Based on the size and location of the cracks in the beam, a combination of low and high pressure was required to inject the repair material into the cracks. Its low viscosity allows CHEMRITE® CILV to be pumped at both low and high pressures, which made it ideal for this job.

​

After completing the repair, cores were taken to confirm penetration. Approximately 20 cores were taken across the beam cracks. Penetration of CHEMRITE® CILV into the cracks was measured to a depth of up to 1000mm, confirming its effectiveness.
