For the 2026 Cranbourne Park car park project, Unison Joints manufactured and supplied 660 metres of waterproof expansion joint seals.
The waterproof seal supplied was Aquo P, a purpose-designed expansion joint water seal suitable for car parks, waterproof decks and other concrete structures where movement and water ingress need to be managed.
Why Waterproofing Expansion Joints Matters
Expansion joints allow sections of a concrete structure to accommodate movement caused by temperature changes, shrinkage, structural movement and other factors.
A failed or deteriorated joint can allow water to penetrate into the structure, potentially contributing to deterioration of surrounding concrete and reinforcement.
Aquo P is designed as a waterproof expansion joint seal, incorporating UV inhibitors and high movement capability. Its welding technology also allows the seal to be formed at junctions and upturns, helping create a continuous waterproofing solution.
With Cranbourne Park accommodating close to 1,700 vehicles and serving millions of visitors each year, maintaining the integrity of its car park infrastructure is an important part of ongoing facility management.
The project showcases the application of a purpose-designed waterproof expansion joint seal in a busy commercial environment, providing a solution engineered for movement while helping protect the underlying structure from water ingress.
The Cranbourne Park project is another example of the importance of selecting the right expansion joint system for demanding car park environments.
