MOT Type 1 0-40mm is a crushed material, usually made from granite or limestone. 

Our MOT Type 1 0-40mm consists of crushed granite stones that can form the sublayer for road surfaces, driveways, patios and pathways. Hardwearing, this gravel provides a load bearing sub layer and a flat surface which is suitable to top with asphalt, concrete, shingle, block and natural paving. The fine mixture within the MOT Type 1 ensures there are minimal voids in the sublayer when compacted creating a solid standing sub-base for any building or landscaping project

 

MOT Type 1, also known as subbase, is a coarse-grained mass commonly used as a layered material covering the subgrade (native material). Thanks to its hardwearing and strength, this granular aggregate is perfect for roads, driveways, patios, paths and even artificial grass.

MOT Type 1 meets the quality standards required by the Ministry of Transport (hence MOT) and it’s a granular material ideal for compact sub-base. MOT Type 1 is made up of a mix of larger pieces measuring 40mm down to dust which compacts strongly to form a solid base, making it a great option to use on: 

 

  • Roads
  • Pavements
  • Drives
  • Patios
  • Garden paths
  • Car parks
  • Trench fills
  • Over-site fills

 

MOT Type 1 forms a stable sub layer that is needed to create a barrier between subgrade soils. Its’ function is to help prevent the pumping of fine-grained, subgrade soils, as it can lead to the loss of soil material beneath the slab edges and joints. It also provides a load-bearing capacity and flattens the surface prior to a top coating of block paving, pavers, shingle, asphalt or concrete. Thanks to its small and dust-like particles, it ensures minimal gaps in the sublayer when compacted.

 

How much MOT Type 1 should be used for hard landscaping?

MOT Type 1 forms a hardcore sub-base for all hard landscaping projects from patio paving to slab laying to driveway paving to artificial grass. It can also be used as a filling material. Usually, MOT Type 1 is laid at a compacted depth of 100mm (around 4 inches) for most patio projects and at a compacted depth of 150mm (around 6 inches) for domestic driveway projects. Compaction should be achieved by using a wacker plate also known as a Vibrating Plate compactor.

MOT Type 1 is commonly used by our clients for its levelling and filling purposes.
