A DIY Guide on How to Lay Crazy Paving

Crazy paving has been a popular choice across Aussie backyards, and for good reason. This freeform, irregular stone layout is full of character and charm, making it perfect for anyone who wants a natural, creative touch to their patio, garden path, pool area, fire pits and more. 

Unlike uniform pavers, crazy paving uses mismatched pieces of natural stone arranged like a puzzle, giving each project a unique look that suits coastal retreats, bush-style homes and everything in between.

If you’ve been inspired by how many Australian homeowners have styled their crazy paving and are wondering how to lay crazy paving yourself, you’re in the right place. We can help you transform any outdoor space with a finish that looks professionally done, whether you’re doing it on your own or with some professional help.

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 with stakes and string or spray paint. Consider drainage as crazy paving needs a slight slope away from buildings to prevent water pooling.

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 and compact it well with a plate compactor or hand tamper. A solid base stops stones from shifting over time.

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 helps you adjust their height. For areas with heavier use or vehicle traffic, mortar bedding is recommended.

Step 4: Place Your Stones

Start laying the largest stones first, puzzling them together with consistent gaps of about 10–20mm. Tap each stone gently into place with a rubber mallet and check for level as you go. Aim for an organic look – random patterns add charm!

Step 5: Cut and Shape as Needed

Fill gaps along edges with smaller stones or trim pieces using an angle grinder or stone cutter. Remember to wear safety gear and take your time to avoid breaking stones unintentionally.

Step 6: Fill the Gaps (Grouting or Pointing)

Brush outdoor-grade grout or mortar into the gaps, ensuring it’s suitable for exterior conditions. Compact gently with a pointing trowel to prevent cracks later and clean excess grout from stone surfaces before it dries.

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 protects against stains, moss and weather damage, especially important around pools or damp areas.

Crazy Paving Tips

• Dry-lay your stones first to perfect your pattern before bedding them down.

• Choose colours and shapes that complement your home’s exterior.

• 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 easier than fixing uneven stones later.
