Benefits
MOT Type 2 provides a durable, low-maintenance solution that improves drainage, prevents erosion, and offers a stable base for various structures. It possesses exceptional load-bearing capabilities and compaction properties, making it an ideal sub-base for roads, driveways, and other areas subjected to heavy usage. Its angular shape not only ensures solid interlock and stability but also contributes to effective water drainage, preventing waterlogging and structural damage.
Applications
MOT Type 2 products are predominantly used in construction and landscaping as a sub-base layer. Its robust structure makes it ideal for supporting heavy loads. Thus, it's commonly found beneath highways, car parks, and driveways. This aggregate's ability to provide a stable, level foundation makes it indispensable for creating solid, long-lasting surfaces. MOT Type 2 is typically used in applications where a more substantial base layer is required. It is often used in the construction of heavy-duty industrial yards or areas with heavy foot traffic.
