Welshpool Concrete (Carlisle) WA
Holcim Australia (Holcim) is proposing a redevelopment of the existing Welshpool Concrete Plant located at 12 Cohn Street, Carlisle within the Town of Victoria Park.
The existing Welshpool Concrete Plant (Carlisle) is located within the Welshpool industrial area (refer to map). It has been in operation since 1959 and is central to Holcim’s servicing of the Perth metro area.
In May 2021, Holcim received approval for the redevelopment of their Welshpool plant, reconfiguring the plant layout and construction of a new concrete batch plant within the site’s existing boundaries. There is now a further need to upgrade the Welshpool site to cater for increased demand from this facility and to serve as a replacement for the impending closure of Holcim’s existing East Perth Concrete Plant.
Holcim’s Welshpool Concrete Plant (Carlisle) is critical to the future development of the Perth CBD and inner metropolitan area. When Holcim’s and Heidelberg’s East Perth Plants close at the end of 2027, it will be the closest plant located to the Perth CBD and vitally important for the uninterrupted supply of concrete (including high specification concrete which must be used within 60 minutes of batching) for a variety of major projects.
Welshpool Concrete Plant (Carlisle) is located within the Welshpool industrial area.
What is Proposed?
The redevelopment will involve construction of a new modern concrete batch plant that is efficient with a reconfigured plant layout within our existing site boundaries. The upgraded plant has been designed to environmental and safety best practice and will have a design life of approximately 50 years, including:
- installation of several additional noise walls within and on the boundaries of the site
Site model.
- facilities for the storage of aggregate (sand, gravel and crushed stone) including an enclosed aggregate storage tower approximately 20.38 metres in height, cement (six cementitious silos with an overall height of 31 metres) and additives and production of concrete
- staff amenities, e.g. office, meeting and training rooms and kitchen
- facilities for the parking and washing out of agitators (concrete trucks)
- car parking for production employees, agitator drivers and visitors (23 parking bays)
These upgrades are proposed to take place over a two-year period commencing in March 2026.

Assessment Process and Study Outcomes
Holcim has submitted a Development Application to the WA Planning Commission under the Part 11B Significant Development Pathway. The Premier has authorised for the application as he deemed the project to be of State importance “on the basis that an uninterrupted supply of concrete is a vital component in delivering a variety of projects in the Perth CBD and inner metropolitan area”. This application is open for public submissions from 10 July through to the 10 August 2025.
Holcim is also preparing a Works Approval Application to be submitted to the Department of Water and Environmental Regulation.
As a part of this process, Holcim has commissioned a number of technical studies to identify potential impacts associated with the redevelopment on our neighbours and appropriate mitigation measures to manage any impacts. These studies have included noise, traffic, air quality, lighting, surface water and visual assessments and preparation of a landscape plan. Key elements of these studies outcomes are included in the Community Information Sheet – July 2025.
