Green360 Technologies Limited (ASX:GT3) has joined forces with PERMAcast, Western Australia’s largest precast concrete manufacturer, to produce low-carbon retaining wall blocks for the state’s fast-growing construction market.

Through a newly formed joint venture (JV), equally owned by both companies, Green360 and PERMAcast will develop a range of sustainable concrete products to meet the rising demand for environmentally friendly building materials. The JV will focus on producing retaining wall blocks for use in infrastructure, residential and mining projects, capitalising on the growing trend toward low-carbon construction solutions.

Strategic partnership to meet market demand

The partnership is formalised through a non-binding Memorandum of Understanding (MoU), which outlines the plan for PERMAcast to fund the acquisition of key equipment, including a block laying machine and concrete batching plant.

The JV will then have exclusive rights to purchase the low-carbon blocks at cost from PERMAcast, with all profits from sales retained within the venture.

“We’re excited to take this step with PERMAcast toward bringing low-carbon retaining wall blocks to Western Australia — a region undergoing rapid growth in urban development, infrastructure and resource-driven construction,” said Green360 executive chairman Aaron Banks.

“Having direct control over the production of our low-carbon retaining wall blocks gives us a significant competitive advantage,” he added. “This level of control also allows for accurate carbon accounting, which is increasingly important for infrastructure and residential projects with net-zero or ESG targets.”

Western Australia’s booming construction sector

The 1,000 x 350 x 350-millimetre retaining wall blocks set to be produced are in high demand across several key sectors in Western Australia, including major infrastructure projects, residential housing developments and mining operations.

These blocks are widely used for retaining walls, road corridors, earthworks, port expansions, and flood and erosion control, with key customers including Main Roads WA, BHP, Rio Tinto, Fortescue, local councils, and residential developers.

Given the region’s rapid urban growth and extensive infrastructure upgrades, there is a clear supply gap in the market for large-format retaining wall blocks that meet low-carbon standards. By developing a local production capacity for these blocks, the JV aims to provide a more sustainable and cost-effective solution for projects that require retaining walls with a reduced environmental footprint.

Sustainability at the core

Green360’s low-carbon retaining wall blocks will be produced using proprietary mix designs incorporating industrial by-products, aimed at reducing the embodied carbon typically associated with traditional concrete. This effort aligns with the broader push toward more sustainable construction methods.

This partnership also complements Green360’s ongoing efforts to expand its portfolio of low-carbon materials, including its work with metakaolin, a key component in low-carbon cement production. The company has also recently made progress in upgrading its demonstration plant for large-scale concrete production.

While the MoU with PERMACAST remains non-binding, Green360 anticipates the block laying machine and batching plant will be operational by mid-2026.
