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
Key Differences:
| Specification | Type 1 MOT | 6F5 Recycled |
|---|---|---|
| Standards | BS EN 13285 | WRAP specification |
| Compaction | Excellent | Good |
| Load bearing | High | Medium |
| Cost | Higher | Lower |
| Availability | Consistent | Variable |
When to Choose Type 1 MOT in Kent:
- Highway and road construction projects
- Load-bearing applications requiring certification

When to Choose 6F5 Recycled:
