The -30mm Ornamental Stone is a chunkier sized product and is used as a cost effective way to replace scoria, and it has a softer more natural appearance. It is a lovely natural product and can be used in garden beds, median strips, pathways and around trees.
The Ginninderra Red Granite has an earthy red colour, when it is first quarried or viewed as a sample it does not appear red but after it has been wet, it oxides and a lovely red colour appears. It is free of African love grass and serrated tussock.
The granite structure insures excellent compaction with an average CBR Value of 60, the plasticity index is 10% and it has a swell rate of 0.0%. (See the latest grading on this site.) The Ginninderra Red porphyry decomposed rock composition makes it unique enabling it to have excellent compaction forming a permanent surface that resists erosion.
It meets the ACT and NSW wearing course specifications as specified in the ARRB group pavement and materials design manual.
