Following the discovery of large cracks in the concrete slabs, a dual use commercial and retail complex in Chatswood was deemed to have structural strengthening issues in the multilevel carpark.
An engineering report was completed and recommended significant structural strengthening was required to 2 levels in the carpark.
The carpark slabs were to be strengthened around the pillars using a unique combination of carbon fibre laminate and carbon rods.
Once completed, the repairs needed to be able to withstand high volume heavy vehicle traffic from both the residential tenants and commercial customers.
The Sika Carbodur rods were laid in the direction of the steel across the slabs whilst the Sika Carbodur S1012 laminate was laid above the rods.
An epoxy repair product Sikadur 31/41 was laid over the top of the repairs to protect the Sika Carbodur, and was sand seeded to an anti-slip and abrasive-resistant surface for the vehicle traffic.
