So, you’re thinking about building a retaining wall? Maybe your backyard’s slowly sliding into the neighbor’s pool, or you just want to level that slope for a killer patio. Whatever the reason, let’s get one thing straight: retaining walls aren’t just stacked bricks hoping for the best. They’re the unsung heroes of landscaping, holding back soil, managing water, and—let’s be honest—making your yard look chef’s kiss.
Here at The Brick Pit in Australia, we’ve seen it all: from Pinterest-perfect walls to “wait, is that supposed to lean like the Tower of Pisa?”. Let’s walk through everything you need to know, including why mortar isn’t just fancy glue and why second-hand bricks might be your new best friend.
Retaining Walls 101: What Even Are They?
Think of a retaining wall as a bouncer for your yard. Its job? To keep soil, rocks, and water in their lane. But unlike bouncers, they don’t need intimidating muscles—just good design and the right materials.
Why Build One?
- Stop erosion: Slopes love to crumble. A wall says, “Not today, gravity.”
- Create usable space: Turn a hillside into a flat oasis for a veggie garden or fire pit.
- Boost curb appeal: A well-built wall adds value (and makes your neighbors a little jealous).
FYI, if you’re in Australia and staring at a crumbling slope right now, The Brick Pit crew can help you sort it—no judgment if your current wall resembles abstract art.
Choosing Your Bricks: New, Recycled, or Sandstock?
Bricks are like ice cream flavors: there’s no one-size-fits-all. Let’s break down your options:
- Recycled bricks: Perfect if you love character (and saving cash). These bricks have stories—chips, weathered edges, and that rustic charm. IMO, they’re ideal for gardens or heritage-style homes.
- Sandstock bricks: Rough-textured and durable. They’re the gym junkies of bricks, built to handle harsh Aussie weather.
- Paving bricks: Smoother and flatter. Great for paths or walls that double as seating.
Pro tip: Always ask, “How many bricks in a pallet?” before ordering. Most pallets hold 400–500 bricks, but sizes vary. At The Brick Pit, we’ll help you calculate exactly what you need—no guesswork required.
Building Your Wall: Tools, Mortar, and Not Cutting Corners
Alright, let’s get our hands dirty. Here’s the lowdown on building a wall that won’t faceplant after the first rainstorm.
What’s Mortar, and Why Should You Care?
Mortar is the “glue” holding bricks together. But it’s not just slapping on some cement mix. The right blend (usually sand, cement, and water) ensures your wall stays upright. Skimp on quality, and you’ll have a crumbling mess faster than you can say, “Oops.”
How to Lay Bricks on the Ground (Without Regrets)
- Dig a trench: Depth depends on wall height, but aim for at least 6 inches.
- Add a gravel base: For drainage—because soggy bricks are unhappy bricks.
- Start laying: Use a string line to keep things straight. Mortar each brick’s edges, and tap them level.
- Backfill with gravel: Prevents water pressure from turning your wall into a waterfall feature.
Common rookie mistake: Forgetting drainage. Water is sneaky—it’ll undermine your wall faster than a toddler dismantling LEGO.

We’ve hauled away enough DIY disasters to fill a landfill. Avoid these face-palm moments:
- Skipping the base: Gravel isn’t optional. Your wall isn’t a sandcastle.
- Ignoring local regulations: Some councils require permits for walls over 3 feet. Check first, or enjoy a hefty fine.
- Using mismatched bricks: Sure, mix recycled and sandstock bricks—but intentionally, not because you ran out mid-project.

FAQs: Your Burning Questions, Answered
1. “Can I use paving bricks for a retaining wall?”
Technically yes, but they’re better for shorter walls or decorative edges. For anything over 2 feet, opt for sturdier sandstock or concrete blocks.
2. “How long does mortar take to dry?”
It sets in 24–48 hours but reaches full strength in about 28 days. Don’t rush it—patience is a virtue, and all that.
3. “Do I need a pro, or can I DIY?”
Small walls? Go for it! But if your slope resembles a cliff face, call in the experts. The Brick Pit can recommend trusted landscapers if needed.
