Sub Base
Type 1 stone is used in the construction of roads as a sub base material. Also can be used as a footway capping layer.
Scalpings are available in various sizes, however the most common being 40mm & 75mm. These are primarily used in the construction of driveways and pathways as a sub base material. Also can be used as a footway capping layer.
Crusher Run is very similar to Scalpings but can also be used as a fill material.
