The right recycled aggregate in the right application performs every bit as well as quarried stone. And at a price that makes the decision straightforward.
Recycled aggregates have come a long way. Once considered a budget alternative to quarried stone, they are now a mainstream material choice across construction, landscaping, and groundworks. They’re tested to the same industry standards, available next day, and significantly kinder to the environment.
The challenge for most people isn’t whether to use recycled aggregates. It’s knowing which one to use. Get it right and your project runs smoothly, performs well, and comes in on budget. Get it wrong and you’re dealing with settling, drainage issues, or a surface that doesn’t hold up the way it should.
Here’s a straightforward guide to the main types of recycled aggregates and where each one works best.
Why Choosing the Right Aggregate Matters
Not all recycled aggregates are the same. They vary in particle size, grading, load-bearing capacity, and the applications they’re suited to. Using the wrong material, even if it’s high quality, can cause problems that are expensive and time-consuming to fix.
The good news is that matching the right material to the right job isn’t complicated once you understand what each product is designed to do. And if you’re ever unsure, our team is always happy to advise before you order.
The Main Types of Recycled Aggregates and Where to Use Them
MOT Type 1 Recycled — The Go-To Sub-Base
MOT Type 1 recycled is the most widely used aggregate in construction, and for good reason. It compacts easily to create a firm, stable base that doesn’t shift or settle under load. If you’re laying a driveway, constructing a pathway, or pouring a concrete slab, this is almost certainly the material you need beneath it.
Best for:
- Driveways and car parking areas
- Pathways and footpaths
- Under concrete slabs
- Roads and access routes
Our recycled MOT Type 1 is manufactured in accordance with the WRAP protocol and independently graded and certified, so you can be confident it meets the same standards as its quarried equivalent.
6F2/6F5 Aggregate — Cost-Effective Capping
6F2/6F5 is a 125mm down to dust material used primarily as a capping layer beneath MOT Type 1. Think of it as the layer that raises and levels the ground before the sub-base goes down. It’s one of the most cost-effective materials available for bulk fill and site preparation, and it’s particularly popular on larger projects where volume matters.
Best for:
- Capping layers beneath MOT Type 1
- Roads and haul roads
- Building foundations
- Footpaths and site levelling
If your project involves significant groundworks or you need to raise site levels before laying a finished surface, 6F2/6F5 is usually the most economical way to do it.
Washed Clean Aggregates — Drainage Done Right
Available in 40-20mm and 75-40mm sizes, washed clean recycled aggregates are the material of choice wherever drainage is a priority. The washing process removes fines and dust, leaving a clean, open-textured stone that allows water to pass through freely.
Best for:
- Soakaways and land drains
- Foundations and sub-bases where drainage is required
- Type B filter media
- Haul roads
If you’re installing a soakaway, creating a drainage layer beneath a patio, or working on any project where water management is a factor, washed clean aggregates are the right call.
Washed Recycled Pipe Bedding — Protecting Your Pipework
Available in 10-5mm and 20-10mm single sizes, recycled pipe bedding is used to surround and protect underground pipework during installation. It provides a stable, cushioning layer that prevents pipes from shifting or being damaged by sharp edges in the surrounding ground.
Best for:
- Surrounding drainage and utility pipes
- Trench reinstatement
- Flagging, screeding, and blinding
- Block paving
Our washed recycled pipe bedding is regularly tested to British Standard BS EN 13242, ensuring consistent quality and performance with every delivery.
Choosing the Right Recycled Aggregate for a Driveway
Driveways are one of the most common domestic applications for recycled aggregates, and the material selection follows a straightforward logic.
Start with a layer of 6F2/6F5 to level and cap the ground if needed. Follow with a compacted layer of MOT Type 1 Recycled as the sub-base, typically 150mm deep for a standard domestic driveway. If you’re finishing with block paving, a layer of washed recycled pipe bedding provides the ideal bedding sand.
This combination gives you a driveway that drains well, handles vehicle loads without shifting, and is built to last, using recycled materials throughout.
Key Questions to Ask Before You Order
Before selecting a recycled aggregate, it’s worth working through a few quick questions:
- What is the surface going on top? Concrete, block paving, tarmac, and loose stone all have different sub-base requirements.
- How much load will the area take? A pedestrian path needs a different specification to a vehicle access road.
- Is drainage a concern? If water management matters, washed clean aggregates or open-graded materials may be more appropriate.
- What volume do you need? Calculate your area in cubic metres and allow extra for compaction, typically 10-15% additional material.
If you’re working through any of these questions and want a second opinion, our team can help you work out exactly what you need before you commit to an order.

FAQs
What is the difference between MOT Type 1 recycled and 6F2 aggregate?
MOT Type 1 is a precisely graded sub-base material used directly beneath finished surfaces such as driveways, paths, and concrete slabs. 6F2/6F5 is a coarser capping material used beneath MOT Type 1 to raise levels and provide a stable platform. On many projects, both are used together.
Which recycled aggregate is best for a driveway?
For a standard domestic driveway, a compacted layer of MOT Type 1 recycled is the most common sub-base choice. For block paving driveways, washed recycled pipe bedding is used as the bedding layer. 6F2/6F5 may also be used if the ground needs levelling first.
Are recycled aggregates suitable for drainage applications?
Yes. Washed clean aggregates in 40-20mm or 75-40mm sizes are specifically suited to drainage applications including soakaways, land drains, and filter media. The washing process ensures good water flow through the material.
How do I calculate how much aggregate I need?
Measure your area in square metres and multiply by the depth in metres to get cubic metres. Allow an additional 10-15% for compaction and wastage. Our team can help you calculate the right volume if you share your project dimensions.
Can PP O’Connor deliver recycled aggregates to domestic projects?
Absolutely. We supply both trade and domestic customers across Greater Manchester and the North West, with next-day delivery available and flexible load sizes to suit projects of all scales.
