If you’ve started shopping for recycled bricks in Australia, you’ve probably hit the same wall every homeowner and builder hits eventually: a supplier mentions “A-Grade” and “B-Grade” bricks like you already know what that means, and you’re left nodding along while quietly Googling it on your phone.
You’re not alone. It’s one of the most common questions we get asked at our Smithfield yard, and it’s an important one because ordering the wrong grade can mean re-doing a feature wall, or paying more than you needed to for a retaining wall nobody will ever see up close.
So let’s clear it up properly. By the end of this guide, you’ll know exactly what A-Grade and B-Grade recycled bricks are, how they’re actually graded (hint: it’s not about colour), which one suits your project, and how much you should expect to pay for each.

What Does “Grade” Even Mean for Recycled Bricks?
Here’s the first myth to bust: brick grading has nothing to do with colour or brand. It’s based purely on the physical form and condition of the brick its shape, how many clean corners and faces it has, and how much wear it’s carrying from its previous life.
Every recycled brick that comes through a yard like ours started life in a demolished building a warehouse, a Federation-era terrace, an old factory wall. During the recycling process, each brick is individually inspected by hand and sorted according to its condition. That’s what determines whether it becomes an A-Grade or B-Grade brick, and it’s a genuinely manual, labour-intensive part of the Brick Rescue process that separates a proper recycler from someone just palletising rubble.
A-Grade Recycled Bricks: The Face-Forward Choice
A-Grade bricks are the cream of the crop from a demolition site. They typically have:
- Four good, clean corners on the visible (“top” or “face”) side
- Minimal chipping, cracking or surface damage
- A consistent, presentable finish suitable for work where the brick will be seen up close
Because of this, A-Grade is the grade you want for anything exposed and on display — a feature wall in your living room, a driveway where you’re looking straight down at the brick’s top face, or an architectural facade where every brick is doing double duty as structure and decoration.
Best uses for A-Grade recycled bricks:
- Paving and driveways (where the top face is constantly visible)
- Feature walls, both interior and exterior
- Fireplace surrounds
- Front-facing garden walls and entry statements
- Any project where an architect or designer has specified a particular look
If you’re after that layered, character-rich look you’ll see in our feature blends hand-blended designer combinations built for architects and custom home projects you’re working in A-Grade territory.
B-Grade Recycled Bricks: The Workhorse Grade
B-Grade doesn’t mean “lower quality” in a structural sense – it means the brick has more visible wear, and is graded on its side face rather than its top face. A B-Grade brick is judged on having four good corners from the side, which makes it perfect for work where bricks are laid on top of one another rather than viewed from above.
Best uses for B-Grade recycled bricks:
- Retaining walls
- Garden edging and boundary walls
- Rendering (where the brick will be covered anyway, so face condition matters less)
- Footings and foundations
- BBQ bases and structural work that will be painted, rendered or otherwise concealed
This is where a lot of Australian renovators can genuinely save money. If you’re building a retaining wall that’s going to be rendered, or a garden edge that’s mostly below eye level, paying A-Grade prices for a job that doesn’t need A-Grade cosmetics is money left on the table. Our combo bricks range includes both Combo A and Combo B grades, individually inspected during recycling, so you can match the grade to the job rather than over-specifying.
A-Grade vs B-Grade: Quick Comparison
| Factor | A-Grade | B-Grade |
|---|---|---|
| Graded on | Top face (4 clean corners) | Side face (4 clean corners) |
| Visual finish | Clean, consistent, presentable | More rustic, distressed, variable |
| Best for | Paving, feature walls, facades | Retaining walls, footings, rendering |
| Typical price | Higher | Lower |
| Where it’s seen | Fully exposed | Often concealed or below eye level |
Does Grade Affect Structural Strength?
This is a common and fair worry. The short answer: grading is about appearance and form, not structural integrity. Both A-Grade and B-Grade recycled bricks go through the same cleaning and inspection process, and reclaimed clay bricks are frequently older and denser than many modern equivalents, having already proven themselves through decades of weather and load.
That said, any masonry work in Australia new or recycled should be built to AS 3700, the Australian Standard for Masonry Structures, which the Housing Industry Association confirms sets the minimum design and construction requirements for brick, block and stone structures nationally, and which the National Construction Code references directly. Grade determines where a brick belongs visually your builder or bricklayer will still design and lay the wall to meet the relevant structural code.
Why This Actually Matters for the Environment (and Your Wallet)
Choosing the right grade isn’t just a cosmetic decision it’s part of what makes recycled bricks genuinely sustainable rather than just a marketing term. According to the Australian Government’s National Waste and Resource Recovery Report 2024, construction and demolition waste made up 29.2 million tonnes — 39% of everything Australia throws away in the 2022–23 financial year, and masonry and building materials had one of the highest recovery rates of any waste category nationally, at 84%. Bricks and pavers alone accounted for roughly 85,000 tonnes of the material stream tracked in one state’s most recent waste report.
Every B-Grade brick that goes into a hidden retaining wall instead of landfill is doing exactly the job the recycling system is designed for and it usually costs less than buying new or over-specifying with A-Grade.
How to Decide Which Grade Your Project Needs
Ask yourself these three questions:
- Will the brick’s top face be looked at directly? (Paving, driveways) → A-Grade
- Will the brick be viewed from the side, stacked in a wall people will actually see? (Feature walls, entry statements) → A-Grade
- Will the brick be rendered, painted, buried, or otherwise hidden once the project is finished? (Retaining walls, footings, garden edging) → B-Grade
If your project mixes both say, a driveway that transitions into a garden retaining wall it’s completely normal (and cost-effective) to order A-Grade for the visible run and B-Grade for the structural sections. Our team can help you work out the split when you get in touch for a quote.
And if your project calls for something with even more history and character than standard reclaimed brick, it’s worth looking at our sandstock bricks Australia’s earliest brick type, dating back to the 1800s, prized for heritage restoration and character-driven builds where grading works a little differently again.

The Bottom Line
A-Grade and B-Grade recycled bricks aren’t a hierarchy of “good” and “bad” they’re two different tools for two different jobs. Get the grading right, and you’ll get the exact look you want for feature work, without overpaying for grade you don’t need on structural sections nobody will ever inspect up close.
If you’re not sure which grade fits your project, that’s exactly what our team is here for. Browse our full range of recycled bricks or contact The Brick Pit with your project details, and we’ll help you get the blend, grade and quantity right the first time.
