Sub base materials

Isle of Wight Aggregates


Type 1

MOT Type 1 Sub-Base material is delivered to our wharves by shipment from our parent company’s quarry at North Wales by Cemex. This product is readily available from our Cowes site for collection or delivery. This material is widely used on our roads, various housing, and other large projects.

All the material is tested and conforms to European Standards.

Type 1 reduced fines

This uniformly graded aggregate material is suitable as a permeable subbase layer for porous surfaced areas, although the stone will have some dust in it but not as much as mot type one or two. Reduced fines is mainly used on tennis courts and football pitches or areas such as driveways so that all water does not go direct to drains.
