Highly compactable
Using processed 20mm, 26mm, 50mm, 80mm or larger compactable aggregate, Heidelberg Materials Coarse Slab Fill delivers a stable surface during construction and is also suited to filling hollows in a cut and a range of other applications. It can be covered post-construction with a concrete slab or planting.
Clean and uncontaminated
Our rock comes from virgin sources that we control so it’s always free of recycled materials, weeds, seeds, organics and other deleterious materials.
Consistent sizing
As the world’s largest aggregate producer, we maintain high quality rock sources in quarry reserves around Australia, and our Coarse Slab Fill is laboratory tested as per project requirements.
