A DIY Guide on How to Lay Crazy Paving

Crazy paving has been a favourite in Aussie backyards for ages, and honestly, it’s not hard to see why. This freeform, irregular stone style is packed with personality, giving patios, garden paths, pool areas, fire pits and more that effortlessly natural, ‘I totally meant to do this’ look.

Unlike uniform pavers that line up like they’re in a marching band, crazy paving uses mismatched pieces of natural stone fitted together like a giant outdoor puzzle. The result? A one-of-a-kind finish that works beautifully for coastal retreats, bush-style homes and pretty much everything in between.

If you’ve been admiring how many Australian homeowners have pulled off crazy paving and you’re wondering how to lay it yourself, you’re in the right place. With the right prep and a bit of patience, you can transform your outdoor space into something that looks professionally installed, even if you’re doing it solo (or roping in a mate for the heavy lifting).

Step-by-Step: How to Lay Crazy Paving

Step 1: Plan and Prepare the Area

Clear your work zone of grass, debris and obstacles. Mark out the layout using stakes and string or spray paint so you know exactly where everything’s going.

Drainage is also a must. Crazy paving needs a slight slope away from buildings so water doesn’t pool and turn your new paving into an accidental bird bath.

Step 2: Create the Base

Excavate the area to a depth that allows for 100–150mm of road base plus the thickness of your stones. Lay the road base evenly, then compact it properly using a plate compactor or hand tamper.

A strong base is non-negotiable. Skip this step, and your stones will shift over time, and not in a cute, artistic way.

Step 3: Add a Bedding Layer

Spread a 30–50mm layer of paving sand or mortar over the compacted base. This layer cushions the stones and gives you the flexibility to adjust heights as you lay them.

If your crazy paving will be in a high-traffic area or exposed to vehicle weight, mortar bedding is the smarter option. Your future self will thank you.

Step 4: Place Your Stones

Start by laying the largest stones first. Fit them together like a puzzle, keeping consistent gaps of around 10–20mm. Tap each stone gently into place with a rubber mallet and check the level as you go.

Aim for an organic, natural look. Random patterns aren’t a mistake here; they’re the whole point.

Step 5: Cut and Shape as Needed

Fill gaps along edges with smaller pieces or trimmed pieces using an angle grinder or stone cutter. Wear safety gear and take your time, because nothing ruins the vibe faster than snapping a stone at the last second.

Step 6: Fill the Gaps (Grouting or Pointing)

Brush outdoor-grade grout or mortar into the gaps, making sure it’s designed for exterior conditions. Compact it gently with a pointing trowel to help prevent cracking later.

Clean excess grout off the stone surfaces before it dries, unless you’re aiming for the ‘oops’ aesthetic.

Step 7: Clean and Seal

Once the grout has cured (usually a few days), sweep the paving thoroughly and apply a high-quality stone sealer.

Sealing helps protect against stains, moss and weather damage, and it’s especially important around pools or damp areas where moisture loves to cause trouble.

Important Tips to Know

• Dry-lay your stones first so you can perfect your pattern before bedding them down.
• Choose colours and shapes that complement your home’s exterior for a cohesive finish.
• Consider flexible mortar mixes in areas with soil movement to reduce cracking.
• If it’s near pools or wet areas, use slip-resistant stones and always seal them.
• Check levels regularly during installation; it’s much easier than fixing uneven sections later.

Crazy paving is the ultimate DIY project for homeowners who want a natural, one-of-a-kind finish that actually looks expensive (without paying someone else to do it). With the right preparation and a bit of patience, you’ll end up with a stunning paved area that stands out from the ordinary.
