How We Tame Runaway Soil (and Look Good Doing It) With Recycled Bricks
Alright, let’s talk dirt. Specifically, the kind that’s trying to make a break for it down your slope every time it rains. Frustrating, right? You’ve put sweat into your garden, and erosion feels like nature’s rude way of undoing all that hard work. Well, grab a cuppa, because we’ve got a solution that’s tough, gorgeous, and kinder to the planet: recycled bricks.
Yeah, you heard us. Those beautiful old red bricks, maybe some character-filled sandstock bricks, or sturdy paving bricks that have already lived a life? They’re absolute rockstars (or should we say brickstars?) for holding your ground. And honestly, using second hand bricks or reclaimed bricks feels pretty darn good – like giving history a second act while saving cash and landfill space. Win-win-win. Down here in Australia, especially with our wild weather, we need solutions with grit. At The Brick Pit, we see it every day – folks turning what others see as waste into garden gold. Seriously, next time you’re pondering brick disposal, think twice!
Why Recycled Bricks Absolutely Rock For Stopping The Slip & Slide
Let’s be real, not all erosion fixes are created equal. Concrete sleepers? Functional, sure, but a bit… meh. Timber? Can rot faster than you can say “termite buffet.” But old used bricks? That’s where the magic happens. Here’s why we’re obsessed:
- Built Tough, Lasts Longer: These bricks have already weathered decades, sometimes over a century! They’ve been fired hard, making them incredibly resistant to cracking and weathering compared to many new materials. They laugh in the face of Aussie sun and downpours.
- Eco-Warrior Cred: Choosing recycled bricks means less demand for new clay extraction and firing (which uses serious energy). You’re literally pulling resources from the waste stream. Feels good, doesn’t it?
- Drainage Champs: Unlike solid concrete, the gaps and porous nature of old bricks let water seep through slowly, preventing the pressure build-up that causes washouts. They manage water, not just block it.
- Instant Character: That mellow patina, the subtle colour variations, the occasional chip telling a story? New stuff just can’t replicate it. Your reclaimed bricks add soul and timeless style instantly.
- Budget Friendly: Often significantly cheaper than new bricks or fancy retaining systems, especially when you find a good local source. More money left for plants!
Finding Your Brick Treasure Trove (Hint: We Can Help!)
“Okay, sold,” you say. “But where the heck do I find these recycled bricks near me?” Great question. Scavenging skips isn’t exactly practical (or legal!), and random online listings can be hit-or-miss.
This is where knowing your local players pays off. For folks in Sydney, Brisbane, Perth, or honestly anywhere across this wide brown land, sourcing quality second hand bricks takes a bit of know-how. You want a supplier who understands salvage, grades bricks properly (so you’re not getting a pile of rubble), and ideally, has a decent range.
- Demolition Sites (Carefully): Sometimes you can find them, but access and quantity are unreliable.
- Marketplace Listings: Can be okay for small projects, but inspect carefully! Hidden cracks or mortar issues are common.
- Specialist Yards: This is where we shine. At The Brick Pit, salvaging and sorting reclaimed bricks is our jam. We’re based in Australia and focus on giving top-quality old used bricks, sandstock bricks, and paving bricks a new life. Why trek all over town when you can find the closest, most reliable source? Give us a buzz – we likely have exactly the character-filled bricks you need, sorted and ready, saving you hours hunting for the nearest option. Finding the right bricks shouldn’t feel like a quest for the Holy Grail!
Get Creative: Brick-tastic Ways To Stop Erosion In Its Tracks
So, how do we actually use these beauties to fight the good fight against erosion? Let’s ditch the boring textbook stuff and look at some practical, stylish ideas:
H2: The Heavy Hitter: Building a Recycled Brick Retaining Wall
This is your go-to for serious slopes. A proper retaining wall made from stacked recycled bricks creates terraced levels, turning a problematic slope into usable, erosion-free garden space.
- H3: Dry-Stacked Charm: No mortar needed! This method relies on careful stacking and slightly stepping each row back into the slope (called “battering”). It’s forgiving, allows perfect drainage, and looks beautifully rustic. Perfect for red bricks or sandstock bricks.
- H3: Mortared Might: For taller walls or a more formal look, mortar adds strength. Pro Tip: Use a lime-based mortar for better flexibility and breathability with old bricks.
H2: Terracing with Tact: Smaller Walls, Big Impact
Don’t need a massive wall? Create smaller terraces using low brick structures. Plant herbs, veggies, or flowers on each level. It breaks up the slope visually and functionally.
H2: Edging Excellence: Brick Borders That Hold The Line
Simple but super effective! Use brick edging along garden beds or paths on gentle slopes. It:
- Defines the space beautifully.
- Stops soil from washing onto paths or lawns.
- Prevents grass roots from invading beds (a sneaky form of erosion!).
Lay them flat, on end (soldier course), or at an angle for different looks. Paving bricks work great here too!
H2: The Stream Saver: Rocking Brick Check Dams
Got a natural gully or channel where water rushes? Small, strategically placed weirs built from recycled bricks across the flow slow the water down, letting sediment drop out before it washes away.
H2: Gabion Genius: Bricks Meet Wire Cages
Love the industrial look? Fill wire gabion baskets with reclaimed bricks instead of rocks. Creates incredibly strong, porous retaining structures. Bonus: It’s a fantastic way to use slightly damaged bricks that are still structurally sound!
Getting Your Hands Dirty: A Basic Guide to Building a Dry-Stacked Brick Retaining Wall
Ready to build? Here’s a simplified rundown for a dry-stacked wall (always check local council regulations for walls over a certain height!).
- Plan & Prep: Mark your wall line. Dig a trench deep enough for a solid base (around 150-300mm deep, wider than your bricks). Bold point: A proper base is NON-NEGOTIABLE for stability.
- Base Layer: Fill the trench with compacted road base or gravel. This provides drainage and prevents sinking. Level it meticulously!
- First Course: Lay your first layer of recycled bricks firmly into the base. Angle them slightly back into the slope (about 10-15 degrees). This “batter” is key.
- Stack & Stagger: Place the next layer, staggering the joints like brickwork always should be. Tap each brick gently with a rubber mallet to seat it firmly. Continue building up, maintaining the slight backward lean.
- Backfill & Drain: As you build, backfill behind the wall with gravel or free-draining soil. Bold point: Install agricultural drain pipe behind the wall at the base, leading to an outlet. This is CRUCIAL to prevent water pressure buildup.
- Cap It (Optional): A final layer of bricks laid flat can give a neat finished top.
Oopsies We See Too Often (Learn From Our “Experience”!)
We’ve seen the good, the bad, and the downright muddy failures. Avoid these common pitfalls:
- Skipping the Drainage: Seriously, this is the #1 reason walls fail. Water must escape. Gravel backfill + ag pipe = happy wall. No drainage = bulging, cracked mess.
- Wimpy Base: Trying to build straight onto soil or sand? That wall is going on a journey downhill. Compacted base material is essential.
- Ignoring the Batter: Stacking bricks straight up? Gravity will win. That slight backward lean is your friend.
- Mixing Brick Types Willy-Nilly: While character is good, wildly different brick sizes or strengths in one course makes stacking stable bricks a nightmare. Sort them roughly by size/thickness.
- Forgetting About Frost (In Some Areas): While less common across most of Australia, if you do get frosts, ensure bricks are rated for it (most old ones are, but check).

Your Burning Brick Questions, Answered
Q1: Are recycled bricks strong enough for a retaining wall?
Absolutely! In fact, many old used bricks, especially dense red bricks or sandstock bricks, are often harder and more durable than some new bricks due to historical firing methods. The key is sourcing quality, uncracked bricks and building correctly (proper base, drainage, batter). We wouldn’t sell them for retaining if they couldn’t hack it!
Q2: How much do recycled bricks cost compared to new?
Generally, recycled bricks are significantly cheaper – often 30-50% less than new equivalents. The exact price depends on type, quantity, and location (getting them from nearby sources like The Brick Pit helps keep transport costs down). FYI, you’re paying for the brick, not the energy to make a new one, plus you’re skipping landfill fees.
Q3: Can I use bricks with old mortar still on them?
You can! It’s called “mortar-cleft.” For dry-stacking, a bit of mortar might even help with friction. For mortared walls, just ensure the mortar bed is thick enough to accommodate the unevenness. For a super clean look, you can have them cleaned, but it adds cost. IMO, a bit of old mortar adds character – it’s proof of their history!
Wrapping It Up (Without Any Loose Soil!)
So, there you have it. Fighting garden erosion doesn’t mean sacrificing style or your eco-conscience. Recycled bricks offer a uniquely beautiful, durable, and sustainable solution. Whether you’re building a mighty retaining wall, some chic brick edging, or creative terraces, those second hand bricks have got the grit to get the job done.
It’s about working smarter, not harder, and giving incredible materials a second life. Next time you see a pile of old used bricks destined for brick disposal, see the potential!
