WESTFIELD CARINDALE – REPLACEMENT OF FAILED CAR PARK EXPANSION JOINTS WITH HEARD GROUP CAR PARK EXPANSION JOINT WATER SEAL SYSTEM
Heard Group Expansion Joint Installations has been replacing failed carpark expansion joint systems throughout the centre’s multi-storey carparks since 2015.
As the centre’s budget allows, Heard Group Expansion Joint Installations has been working through the numerous square metres of rooftop car park replacing the centre’s failed expansion joint covers with the Heard Group Car Park Expansion Joint Water Seal.
The Heard Group Car Park Expansion Joint Water Seal is a car park expansion joint with a 100% water proof barrier, that allows motor vehicles pedestrians and trolleys to easily traverse the joint. No noise, no water leaks, no trip hazards and no expensive aluminium rails required.
The previous car park expansion joints were causing the centre’s management major headaches each time it rained. That is, each time it rained water would leak through the failed expansion joint and into the retail stores below causing both retail tenant and customer complaints. The metal cover plates were also a significant noise hazard. When cars traversed the failed joint they would make loud banging sounds as a result of the fixings continuously becoming loose and unable to be held into the concrete slab by fixings. The joints were also causing pedestrians to trip when they attempted to cross them and trolleys pushed by customers were difficult to get over the joint. This resulted in further complaints to management and in some case personal injury.
Unfortunately when the failed expansion joints were removed they left spooled and cracked concrete as a result of the fixings cracking the concrete slab during thermal movement. The Heard Group Polymer Nosing System was used to repair the damage to the concrete. The Polymer Nosing System is an elastomeric epoxy repair system that is stronger than concrete. It’s used to not only repair spooled and cracked concrete but also as a bedding filler for expansion joint covers.
