The TurfWorld MOT Type 1 Sub Base is designed for professional landscapers, contractors, and DIY enthusiasts who require a heavy-duty, load-bearing foundation for construction projects like driveways, patios, and garden paths. Its key benefit lies in its Department for Transport (DoT) specification grading, which ensures superior compaction and long-term stability to prevent sinking; however, users should note that the significant 850kg weight requires mechanical handling or a clear plan for heavy-duty site access.

For most domestic driveways, a depth of 100mm to 150mm is standard after full compaction.
No, MOT Type 1 is a structural sub-base. It should be topped with a decorative material like gravel, sand, or paving slabs.
You will need professional delivery equipment; do not attempt to move the bag manually. Ensure your site has access for a heavy goods vehicle (HGV) with a crane.
Yes, while it compacts into a solid mass, the graded nature of the stone allows for natural drainage, preventing water from pooling under your paving.
It means the material meets the official standards set by the Department for Transport for use in highway and public construction, guaranteeing high quality and structural reliability.
Ensure you are using a mechanical vibrating plate compactor rather than hand-tamping, and check that the material depth is uniform across the entire area.
If the material is bone-dry, lightly dampen it with water before using the compactor; moisture helps the fine particles bridge gaps between the larger stones.
Preparation for this product involves clear site access, as the bulk bag will be delivered via a crane-equipped vehicle. Ensure the drop zone is flat, solid, and easily accessible from the roadside.
Compatibility:
This aggregate is compatible with most surface materials including block paving, flagstones, resin-bound surfaces, and asphalt. It should not be used as a final aesthetic top layer, as it is strictly a structural sub-base.
Care:
While MOT Type 1 is a low-maintenance, inert material, it must be protected from rainfall before installation if kept in the bag for an extended period to prevent the fines from becoming overly saturated and difficult to work with. Once installed, it requires no maintenance provided it is covered by a suitable paving or surfacing material.
