Minus 19mm Crushed Limestone is typically used as a sub-base for trafficable areas such as driveways and footpaths. The crushed limestone is spread and compacted to provide a firm base for laying and screeding paving sand prior to installing brick pavers or concrete.
Dependent on personal preference, Minus 75mm Crushed Limestone can also be used for this purpose however it is generally used more for roadways and access tracks.
This crushed limestone is a ‘minus’ product, meaning it is not graded to a single sized stone, rather sized from 19mm down to dust/fines.
