what we do

Precast Concrete Aust (PCA) is a Brisbane-based company that makes sustainable precast concrete products from mostly recycled construction and demolition waste. Our products have found use across the civil, mining, agricultural, earth retention and materials storage industries.

​

Our focus is making sustainable precast concrete products. Our concrete products are made from recycled materials without compromising quality, strength or appearance whilst remaining competitively priced and economically viable. Our raw materials are reclaimed from locally sourced construction and demolition waste. We invest heavily in research and development to find novel uses for waste products that currently do not have industrial applications. We offer a whole of life product stewardship program to help clients reuse, repurpose or recycle their unwanted concrete products.

what makes us different

Precast concrete is our one and only game and not a side hustle or a nice to have hobby. 

​

We batch our own concrete from our own raw materials and do not rely on returns from concrete trucks driving around town.

​

We keep stock of our most common items and we are able to make to order as required. We provide realistic timelines and provide updates on orders and dispatch.

​

Cheap concrete block prices may seem too good to be true, and that's because they usually are. Do your research, ask around and come and inspect the blocks if you need to. It could save you a lot of heartache (and money) in the long run. â€‹
