Dark retaining wall blocks, Rockhampton

"This EPD covers all dark coloured concrete retaining wall blocks produced at our Rockhampton Queensland location which manufactures under the Austral Masonry brand.

The life cycle of concrete retaining wall blocks starts with extraction of sand, gravel from quarries and mines and production of cement.

The processed materials are then mixed with oxides and moulded into the desired block shapes in a manufacturing plant. "
