When to Choose Recycled Aggregates for Your Subbase

Subbase is the backbone of most building projects. Regardless of whether you’re laying a road, car park or pavement, if the foundation underneath isn’t laid correctly, the structure won’t last long.

Traditionally, the construction industry has chosen hardy materials like granite or limestone as subbase, but that doesn’t mean they’re the best choice for every project.

Recycled aggregates are a great alternative that has many of the properties of virgin aggregates, whilst promoting more sustainable construction practices, at a lower cost. Made from old construction waste, typically from demolition sites, materials like bricks, concrete, and asphalt are crushed down and recycled for reuse.

That said, just like other aggregates, recycled aggregates may not be suitable for every project. So, how do you decide? Let’s discuss four situations where recycled aggregates might be a good choice for your project.

1. Budgeting Reasons

If you’re planning a construction project, you’ll need to budget wisely to avoid overspending on construction materials and labour. In many cases, recycled aggregates can be much more cost-effective.

They’re cheaper to produce as the supplier doesn’t have to source virgin materials from the ground. They simply have to crush and clean what’s already there and process those aggregates for construction use.

For projects with a tight budget, this can make a big difference. Whether you’re laying out a long car park or resurfacing a footpath, the costs add up. Saving here means you’ll have more money to spend elsewhere.

You’re not trading off quality either. Recycled concrete aggregates meet the industry standards and perform just as well in many subbase applications.

2. Material Variability

Not all builds need perfect consistency. Some projects can handle some variation in what goes under the surface. In these cases, recycled aggregates can be a great option.

There are many types of recycled aggregates, and this naturally leads to some variability in texture or colour. For non-structural groundwork, footpaths, or light-use driveways, this may not be a problem.

In these cases, the material still compacts well and performs reliably as a subbase. Choosing recycled options when suitable doesn’t just reduce costs, it simplifies sourcing too.

You can often get what you need locally and quickly, without strict specifications slowing your project down. If the project isn’t too demanding and allows for slight material variability, recycled aggregates are a practical and efficient choice.

3. For a Stable, Well-Drained Ground

Ground conditions are a significant deciding factor. If the soil is already stable and drains well, recycled aggregates can work exceptionally well for the subbase.

These aggregates give solid support, especially on ground that doesn’t shift or hold water. Since you aren’t fighting against nature here, the subbase doesn’t need to do all the heavy lifting.

Recycled concrete aggregates, in particular, have great load-bearing strength and compacts well. If the ground is already doing half the job, you don’t need to stress too much over your subbase choice. Recycled aggregates are a more cost-effective choice and fill the gap effectively.

4. Compliance with Sustainability Guidelines

Some local councils now encourage greener construction methods. In certain areas, using recycled materials is preferred, and sometimes, it’s even a requirement.

Recycled aggregates help meet these guidelines without adding extra pressure to your project. They help you cut down on landfill waste, lower your carbon footprint, and support circular economy goals.

If you’re bidding for public contracts or working on council-led building projects, showing sustainable material use can be a big plus. It’s one of those things that ticks a lot of boxes.

To reiterate, you’re not sacrificing performance. Most types of recycled materials meet key compliance standards and will bring lasting results to your project.
