Type 1 MOT vs 6F5: The Complete Kent Guide

Choosing the right recycled aggregate for your Kent construction project is crucial for both performance and cost-effectiveness. Two of the most commonly specified materials are Type 1 MOT and 6F5 recycled aggregate.

What is Type 1 MOT?

Type 1 MOT (Ministry of Transport) is a crushed aggregate blend meeting strict gradation requirements. In Kent, we supply both primary and recycled Type 1 MOT suitable for:

  • Road sub-bases - Meeting highway specifications
  • Car park construction - Load-bearing applications
  • Foundation bases - Under concrete slabs
  • Drainage projects - Pipe bedding and surround

What is 6F5 Recycled Aggregate?

6F5 is a recycled aggregate produced from crushed concrete and masonry waste. Popular across Dover, Canterbury, and Maidstone for:

  • General fill - Non-structural applications
  • Hardcore layers - Under buildings and hardstanding
  • Drainage applications - French drains and soakaways
  • Landscaping projects - Base for block paving
