Experience in high-rise construction

Name of project:

Various Gold Coast high-rise buildings



Gold Coast, Queensland


Project details:

Crown Towers

Hymix supplied Multiplex with over 35,000 cubic metres for this 40-story tower, located on the Gold Coast. That included construction of the high-rises 293 luxurious hotel rooms and apartments, its swimming lagoon (the largest in the Gold Coast) and an island linked by two suspension-style bridges.


The concrete had to fulfil very specific high-building demands. A 40 and 50MPa product was developed by Hymix’s technical team for the majority of the building. A super plasticised mix with a high 180mm+ slump was also used for the walls of the Tower.


Over 2400 cubic metres of concrete was poured for the tower’s raft-slab foundation. This proved to be demanding in terms of planning and logistics, as it was delivered over two individual 1200 cubic metre pours, requiring sixty Hymix trucks and six concrete pumps. All concrete was loaded from Hymix’s Southport and Burleigh plants and represented the two biggest single pours on record in the Gold Coast.


Freshwater Point Apartments

This medium-density waterfront complex is located in Broadbeach, adjacent to Jupiter’s Casino. It was developed by Matthews Property Group, a Hymix customer now for over twenty-two years.


The project contains 255 apartments with a wide variety of plan configurations and sizes. It also features extensive on-site facilities including a two-story basement car park, pools, contemporary BBQ areas and a private fishing jetty.


23,000 cubic metres of Hymix 40MPa concrete was used to construct the complex. It gave shape to the design aspirations of Burns Design Architects, producing the buildings elevations with a strong horizontal emphasis as well as the roof overhands, cantilevered balconies, blade walls and suspended frame elements.



Ensuring all of the apartments offered privacy for their occupants was a critical concern, so a range of screening devices including deep balcony hangings, overhanging roofs and external louvred screens were also constructed. Much of this concrete had a painted finish.


All of the concrete was placed by Hymix in a three month period, with pours ranging from 500 cubic metres to 1,100 cubic metres every second day. Each pour was controlled on-site by John Gill, Customer Service Manager and this played a key role in ensuring the project was completed in a remarkably short time frame of only ten months.


ANA Towers and Gold Coast International Hotel

These two Surfers Paradise landmarks were constructed by Barclay Mowlem. Hymix supplied concrete for both projects simultaneously, with over 65,000 cubic metres poured in total.
