MOT Type 3 is a product made from crushed Granite, Basalt, Gritstone or Carboniferous Limestone (depending on source).
MOT Type 3 is a suitable sub-base for driveways, footpaths, permeable paving, concrete bases, car parks, patios, SUDS applications etc.
MOT Type 3 is perfect for driveway sub-bases where the finished surface needs to comply with Sustainable Urban Drainage regulations (SUDS), such as when used with permeable paving.
MOT Type 3 should be laid at 150mm depth when used as a driveway sub base for car traffic. Heavier loadings will require a deeper sub-base and may need to be calculated by a structural engineer. Generally path sub bases should be 75mm depth whilst patio sub bases laid at 100mm depth. Typically, one of our Bulk Bags will cover 5m2 at 100mm depth. For larger areas you may wish to use our quantity calculator located at the top right hand side of this page under the grey "How Much Will I Need" tab. Simply enter your measurements to reveal the required tonnage. Please be sure to enter the length and width figures in metres and the depth in millimetres to give the correct quantity.
MOT Type 3 should be spread with a shovel and compacted with a whacker plate or vibrating roller in layers. It is important the product is properly compacted to prevent settling later on. The depth of installation will depend on the project but we generally recommend 150mm for driveways, 75mm for paths and 100mm depth for patios
MOT Type 3 is produced to comply with the Specification For Highways Works Clause 805 (SHW805). This ensures a consistent product that is resistant to frost heave.
MOT Type 3 is a free draining sub base. Visually it is very similar to Type 1, however, it has a lower fines content and greater void ratio.
