Sometimes also called DOT Type 1, for the Department of Transport, MOT Type 1 is only lightly permeable, and is therefore not SuDS compliant, according to the Department of Transport Specification for Highway Works.
SuDS compliance relates to Sustainable Urban Drainage Systems, which rates the permeability of construction materials – quite often deciding what the aggregate can then be used for.
This means contractors and site managers would be best opting for MOT Type 3 if they are constructing features or working on projects that need permeability, including roads and other public highways.
If permeability isn’t an important factor for your project, you can order great quality recycled MOT Type 1 aggregate from Grundy & Co. Simply fill in the enquiry form on your screen or email us at sales@grundyandco.com and we’ll get back to complete your order and arrange a convenient delivery.
