MOT Type 2 Sub-Base (SHW Clause 804)

A free-draining, compactable sub-base for paths, patios, and permeable driveways.

Type 2 Sub-base aggregate, also commonly referred to as MOT Type 2 aggregate is an unbound mixture of aggregates that is defined by Clause 804 of the Standards for Highway Works. Type 2 aggregate is a finer grade of sub base material than Type 1, and is typically used in applications where a more substantial base layer is required.

Type 2 aggregate can be derived from recycled waste materials sourced from construction and demolition projects, reducing the need for quarrying virgin aggregate. This not only preserves natural resources but by repurposing waste from construction and demolition projects, there is a reduction in the amount of waste going to landfills, promoting sustainable and eco-friendly construction practices.

Our Type 2 aggregate is supplied across our network of quarries nationwide. Whether you're a professional in the construction industry or a homeowner looking to improve your property, our Type 2 aggregate can benefit any project. And, with a comprehensive transportation network, we are able to provide flexible and rapid delivery across the UK. 

Composition

Type 2 aggregate consists of aggregate that is crushed and screened typically to 63mm down to dust. The coarse nature of the aggregate blend means that it provides a free-draining base, making this a popular choice of sub-base for pathways and walkways. Easily compacted, you can also utilise Type 2 as a backfill material.

Benefits

Specifications Compliant

Like MOT Type 1, MOT Type 2 aggregates comply with standards for highway construction, including the Department of Transport’s Specification for Highway Works. This makes it a reliable choice for infrastructure projects where regulatory compliance is essential.

By incorporating recycled materials, MOT Type 2 aggregates offer a more sustainable option for construction projects. Utilizing recycled content reduces the demand for new quarried stone, conserving natural resources and lowering the environmental impact of the construction process.

Compaction and Stability

MOT Type 2 aggregates provide good compaction properties, creating a stable, load-bearing sub-base for projects like roads, driveways, and car parks. Once compacted, Type 2 forms a solid base that supports heavy loads, minimizing settlement and subsidence over time.

Why use A Type 2 aggregate?

MOT Type 2 aggregates are versatile and widely used for constructing sub-bases in a variety of infrastructure projects. Composed of crushed stone and recycled materials, they offer several benefits for groundwork and construction applications. 

The moderate fine content in MOT Type 2 aggregate helps to prevent water from being trapped in the sub-base, which reduces the risk of frost heave in colder climates. This makes it suitable for applications where frost resistance is important, like roadways and driveways, especially in areas with freeze-thaw cycles.

MOT Type 2 aggregates are relatively easy to work with and compact, allowing for quicker installation in construction projects. Its ease of use, coupled with its affordability, makes it a popular choice for both commercial and domestic applications.

  • Car parks: where a stable, load-bearing sub-base is required.
  • General landscaping: such as beneath patios or garden paths.

Specification

  • Complies to all standards outlined in Clause 804 of the Standards for Highways Works
  • Sustainable options available, blending recycled content sourced from construction demolition materials
  • Screened to 63 mm down to dust
