🚧 What is MOT Type 1 and Why is it Essential in Construction? 🚧

When it comes to building solid foundations—whether it’s a road, driveway, car park or construction site access—there’s one name that keeps surfacing in the aggregates world: MOT Type 1. But what exactly is it, and why is it so important in the construction industry? Let’s dig in. 🛠️


🪨 What is MOT Type 1?


MOT Type 1 is a crushed aggregate material approved by the Ministry of Transport (MOT)—hence the name. It’s typically made from a mix of crushed limestone, granite, or concrete, and graded from 40mm down to dust. This composition makes it perfect for compacting into a stable base layer.

At Bailey Earthmoving, we supply high-quality MOT Type 1 aggregate straight from the quarry, ensuring your groundwork starts with the right stuff beneath your boots 👷‍♂️.


✅ The Key Benefits of MOT Type 1


  • Excellent Compaction 🔒 – The mix of fine particles and larger chunks ensures tight compaction, creating a firm and level base.
  • Permeability 💧 – It allows for sufficient drainage while maintaining strength—ideal for avoiding waterlogging.
  • Strength & Load-bearing 🚚 – Designed to withstand heavy loads, making it perfect for roadways and HGV-access areas.


If your project involves building something that people (or machines) will be driving or walking on—this is your go-to material.


🏗️ Common Uses of MOT Type 1 in Construction


  1. Road Construction 🛣️
    It’s the primary sub-base for roads, motorways, and laybys—especially where strength and durability are key.
  2. Driveways & Paths 🚶‍♀️🚗
    Whether it's a residential drive or a rural farm track, MOT Type 1 lays the groundwork for longevity.
  3. Car Parks & Loading Bays 🅿️📦
    Its load-bearing capacity makes it ideal for commercial and industrial parking areas.
  4. Foundations for Buildings & Sheds 🏠🔨
    Before pouring concrete, MOT Type 1 creates a level, stable surface that reduces movement and cracking.
  5. Temporary Site Access Roads 🏕️🚜
    For construction sites with heavy machinery, MOT Type 1 helps avoid muddy messes and stuck vehicles.
