Expansion Joint Systems for Car Parks by Unison Joints

The combination of high volumes of vehicle weight, vibration, shrinkage and expansion are all concerns when designing a safe and stable car park structure. To accommodate such concerns, expansion joint systems for car parks are designed to alleviate thermal-induced movement and to strengthen the structural design.

Since parking is one of the most important aspects of today's mobile community, provisions for parking spaces are now growing at an increasing rate. This means that new parking spaces are being built and existing car parks are being refurbished or extended to meet the growing demand for parking spaces.

The success of a car park is based on its structural and architectural design, safety, security and its ability to traverse premature deterioration caused by leaks, heavy traffic load and water infiltration via joints. Car parks require good resistance to such effects for everyday traffic use. Parking spaces for all major establishments, such as shopping centres, office buildings, hospitals, stadiums, airports, terminals, and wharves - need to cater for not just vehicular traffic - but also pedestrians, shopping trolleys, prams and other forms of traffic.

Car Parks are typically exposed to the following stressors:

Thermal changes and movement
Rainwater
Automotive fluid
Pedestrian and other traffic
Differential vertical movement at expansion joints
Movement caused by seismic activity
Groundwater

Expansion joint systems for car parks can be integrated to fit the structural design and functional aspects of newly constructed car parks and for refurbishing old parking spaces.

By150N/AqP Carpark Expansion Joint Systems from Unison Joints

The By150N/AqP uses the existing AqP polyethylene seal system to create a 100% watertight seal. The AqP (formerly UPB) has been installed to the extent of 17 kilometres of product in commercial and public buildings in Australasia and the Middle East. The AqP has been highly successful in preventing leaks through movement joints both internally and externally for 15 years.

The flexibility and versatility of the AqP expansion joint system make it ideal to use in high-movement areas, such as car parks, wharves, and in other concrete or masonry movement joint applications. Unison's By150N is one of the cover systems offered for use with the AqP. These protective covers offer trafficable support for vehicle, trolleys, and pedestrians, forklifts, maintenance equipment, and other traffic.

ByN is designed for use in open-air and covered carparks with suspended slabs. It is a surface or flush-mount system made of high grade anodised aluminium extrusions and a neoprene pad. The complete system has numerous design advantages over other carpark expansion joint systems: There is no water seal compromise at T and crossover junctions... or at upturns in expansion joints. The By150N system is very simple to install at all locations including wall-to-floor transitions, and therefore provides a neat, professional aesthetically-pleasing finish. This expansion joint system has differential movement capacity, as well as lateral, longitudinal and other directions.

Unison Joints works closely with clients to ensure that their needs and expectations are being met. Unison takes pride in designing and manufacturing building expansion joint systems that meet Australian Standards and the National Building Code.
