The Project
Project Details
Crown Towers Perth represents the largest hotel constructed in Western Australia, incorporating 500 luxury rooms, suites and villas within a world-class resort complex spanning over 40,000m². The hotel tower consists of 453 standard rooms and 47 villa and suite rooms with high-end gaming and ultra-lounge spaces. A new three-level podium links the existing Crown Metropol hotel complex with Crown Towers, containing a new hotel reception, bars, restaurants, ballrooms and conference facilities.
To meet the highest performance and sustainability standards, the project focused on:
- Delivering robust below-grade waterproofing and gas mitigation protection across the entire 40,000m² building footprint
- Providing ultra-fast curing systems to optimise construction scheduling and enable rapid return to service across multiple work zones
- Ensuring long-term chemical resistance and wear performance suited to a luxury hospitality environment with high operational demands
Envirosystems Solution
Envirosystems selected Enviro HP1600 to use across 40,000m² of the Crown Towers Perth project, deploying this heavy-duty spray-applied polyurea system for its proven track record in waterproofing and gas mitigation applications. As a two-component spray-applied system, Enviro HP1600 optimises the fast-setting properties of polyurea technology, allowing areas to be returned to service quickly and supporting efficient construction sequencing across the extensive project footprint.
Enviro HP1600 exhibits excellent waterproofing capabilities combined with low VOC content of 13g/L, high wear resistance and chemical resistance essential for hospitality infrastructure. Installed with the custom-designed Envirosystems gas venting system, Enviro HP1600 provided comprehensive protection across the entire Crown Towers development. As part of the Enviro HP Series range of premium spray-applied polyurethane and polyurea elastomers, the system delivers ultra-fast curing and superior waterproofing properties backed by extended warranties when applied by accredited applicators.
