Stone Testing

Confidence + Consistency

All Bamstone products have undergone extensive qualitative and quantitative testing by Stone Initiatives, an independent NATA-accredited laboratory specialising in dimension stone, to ensure consistent and premium supply of Australian bluestone.

Industry stone testing determines the properties of the material and its fitness for use in public and private spaces. Stone is a natural product that can vary in appearance and physical properties throughout the quarry. Regular testing allows us to understand the strengths, weaknesses, and any variability within the stone.

Over the years, Stone Initiatives have conducted extensive research and testing of Bamstone bluestone. This testing ensures that the products we provide, derived from the natural bluestone resource at our local quarry site, are of incredible quality – setting the bar high on a global scale.
