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.

The 14-level hospital at Westmead serves as the centrepiece of the New South Wales Government’s $1 billion-plus Westmead Redevelopment. Designed by HDR Rice Daubney, this comprehensive healthcare facility features two new emergency departments – one for adults and one for children with dedicated entry points, 20 new operating and interventional suites with highly specialised technology and equipment, a new Cardiac Comprehensive Care Centre, over 300 new patient rooms, and extensive education, training and research areas and facilities. The scale and complexity of this landmark healthcare project demanded waterproofing solutions capable of meeting stringent hospital standards across diverse applications.

To meet the highest performance and sustainability standards, the project focused on:

• Delivering reliable below-grade waterproofing protection for lift pits and basement structures supporting critical healthcare infrastructure
• Providing vapour-permeable membrane systems with excellent freeze-thaw durability suited to long-term healthcare facility requirements
• Ensuring high-quality, flexible waterproofing with outstanding adhesion properties for concrete, masonry and natural stone substrates throughout the complex

Envirosystems Solution

Envirosystems Hydrostatic 1 solution was installed during the early works stage to the lift pits at Westmead Hospital. Based on advanced cross-linking polymer technology, Enviro Hydrostatic 1 is a single-component flexible polymer-modified cementitious membrane. The addition of water to the Hydrostatic 1 powder forms a high-quality liquid membrane system designed for application over concrete, masonry and natural stone substrates.

The cured film provides a watertight membrane that remains permeable to vapour diffusion, offering excellent freeze-thaw durability and outstanding adhesion properties essential for below-grade applications. This system proved ideally suited to the demanding requirements of the Westmead Hospital Redevelopment, providing reliable waterproofing protection for critical infrastructure supporting the 14-level healthcare facility and its specialised medical services.

Project Details

The $790 million redevelopment transformed Liverpool Hospital into a world-class medical hub and one of New South Wales’ leading health precincts. This comprehensive project included the reconfiguration of existing car parks, a new kitchen facility, a new mortuary, helipad upgrades and a temporary education facility to enable continuous hospital operations throughout construction. The Liverpool Health and Academic Precinct will feature approximately 900 beds (an increase of over 20 per cent), significant expansion in ambulatory services with almost double the chemotherapy treatment spaces, expanded women’s and children’s services including 16 new birthing suites and 50 NICU and Special Care Nursery beds, a larger emergency department and intensive care unit, additional theatres, and a new multi-storey car park.

To meet the highest performance and sustainability standards, the project focused on:

• Delivering low-VOC, environmentally responsible waterproofing systems suitable for sensitive healthcare environments with strict standards
• Providing reliable protection across diverse applications including mortuary facilities, kitchen areas, helipad surfaces and expanded clinical spaces
• Ensuring long-term durability and performance for critical healthcare infrastructure serving one of Sydney’s fastest-growing regions

Envirosystems Solution

Envirosystems was used for the Liverpool Hospital redevelopment, delivering waterproofing solutions across the early works phase and preparing for the main construction programme. The specification addressed diverse applications including car park reconfigurations, the new kitchen facility, mortuary, helipad upgrades and temporary education facilities.

The Envirosystems products provided reliable, environmentally responsible waterproofing protection suited to the demanding requirements of healthcare infrastructure. The systems ensured appropriate performance standards for sensitive medical environments while supporting the hospital’s continued operations throughout the staged transformation into a world-class health and academic precinct serving the Liverpool community and broader region.

Project Details

This project involved the complete reconstruction of an outdated 20-storey 1970s office building, transforming it into a signature development in the heart of Sydney’s CBD. The existing building was stripped back and rebuilt to include a new high-performing, environmentally responsive facade system, setting a world-class standard for energy efficiency in commercial buildings. The development encompasses A-grade office space, premium retail and basement car parking, and won an MBA award for Site Safety Commercial Projects $50 million and over.

To meet the highest performance and sustainability standards, the project focused on:

• Delivering low-VOC, environmentally responsible waterproofing systems aligned with the building’s world-class energy efficiency and sustainability credentials
• Providing specialised solutions across diverse applications including green roofs, portable water tanks, wet areas, plant rooms and blindside membranes
• Ensuring UV-resistant and root-resistant systems capable of protecting complex building elements in a premium CBD development

Envirosystems Solution

Envirosystems was selected as the supplier of low-VOC waterproofing membrane systems for the reconstruction of 20 Martin Place, adding to the list of high-profile tier-one developments incorporating Envirosystems technology. Products were selected based on proven track records in similar projects and the environmentally friendly nature of the solutions, ensuring alignment with the building’s sustainability objectives.

The comprehensive list of products included Enviro 200P Ultra for wet area walls, Enviro Epoxy RC for pump room floors, plant rooms and sumps and Enviro HP1600 for blindside membrane applications. These Enviro products proved to be high-quality, low-risk alternatives to other waterproofing systems on the market, delivering reliable protection across the diverse applications of this critical CBD infrastructure.
