MOT Type 1 is the construction industry’s go-to sub-base material, renowned for its reliability and performance in a variety of applications. Composed of high-quality granite, limestone, basalt, or gritstone, this crushed aggregate ranges from 40mm down to dust, creating a highly compactable material ideal for creating a solid foundation. With excellent load-bearing qualities, it ensures a durable, stable base for your projects.
Also known as DOT Type 1, named after the Department of Transport (DOT) specification for granular sub-base material, MOT Type 1 adheres to the rigorous standards set by the Department of Transport Specification for Highway Works (Clause 803, SHW 803). This makes it the most widely used approved sub-base in the construction industry, trusted for its performance and consistency.
Unlike scalpings, which contain a higher fines content and have reduced load-bearing capabilities, MOT Type 1 boasts a range of particle sizes that make it both easy to compact and ideal for heavy traffic areas. It’s the perfect choice for highways, car parks, driveways, footpaths, building bases, and other applications where a strong, firm sub-base is essential.
