Car parks are exposed to heavy loads, changing temperatures, vehicle movement, and water ingress. Over time, these factors can cause concrete slabs to crack, spall, or shift—leading to expensive repairs, safety risks, and operational downtime. That’s where expansion joints become essential.
Unison Joints expansion joints are engineered to protect car park structures by accommodating movement, absorbing stresses, and maintaining surface integrity.
Why Car Parks Need Premium Expansion Joints
Car parks differ from standard floor surfaces because they experience:
✔ Heavy wheel loads from cars, trucks, and service vehicles
✔ High-frequency traffic in all directions
✔ Exposure to rain, UV, oil, and chemicals
✔ Large surface areas with temperature variances
These conditions demand joints that don’t just fill gaps—but actively protect the structure. Built to absorb movement and resist load transfer, these joints provide: Excellent weather resistance for outdoor car parks Superior flexibility for temperature and structural movement High load capacity for vehicles and occasional heavy equipment Custom sizing for exact application Easy installation Seamless integration with concrete surfaces Optional sealants and profiles help Prevent Leaking to lower decks
