PTC Chatswood Carpark structural strengthening

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 Sikacarbodur S1012 Laminate was laid above the rods
• An Epoxy repair product Sikadur 31/41 was laid over the top of the repairs and to protect the Sikacarbodur and was sand seeded to an ant slip and abrasive resistant surface for the vehicle traffic
