Sub base
Sub base is an important part of the layering required to make a suitable outdoor foundation, used most often for drives, gardens and pathways. Subbase sits above the subgrade level and below the base course. Having all the layers in place will allow for a solid foundation that will not be affected by movement and it will also allow excellent drainage.
