Type 1 Sub Base

Type 1 Sub Base, also known as MOT 1 Sub Base has crushed gravel stones mixed with stone dust that form the sublayer for patios, concrete bases and pathways.  Hardwearing, this gravel provides a load bearing stable layer and a flat surface prior to a top coating of asphalt, concrete, shingle or block paving. The fine mixture also ensures minimal voids in the sublayer when compacted.
