Crazy Pavers vs Concrete Pavers — Adelaide Comparison

Crazy paving and concrete pavers are at opposite ends of the paving spectrum — one is rustic, irregular and labour-intensive, the other is uniform, modular and fast. The right choice depends on the look you want, the budget, and the maintenance you’re willing to do.

At a glance

	Crazy paving	Concrete pavers
Look	Rustic, organic, irregular	Clean, uniform, modular
Per-sqm cost (installed)	$130–$220	$70–$95
Lifespan	30+ years	25-40 years
Repairability	Hard — replace whole sections	Easy — replace individual pavers
Drainage between joints	Slower, mortar-bedded	Faster, jointed with sand
Best for	Heritage homes, character courtyards	Driveways, large patios, pool surrounds

What is crazy paving

Crazy paving uses irregular, broken pieces of natural stone (sandstone, slate, bluestone, granite) laid in a random pattern. Joints are mortared, not sand-jointed like modular pavers. The labour is largely in shaping cuts, dry-fitting the puzzle, and grouting joints to a smooth finish.

The natural-stone version uses real broken stone. Cheaper crazy-paving variants use concrete pieces designed to look broken — they save 30-40% on materials but lose much of the character.

What concrete pavers are

Concrete pavers are pre-cast modular blocks (typically 200×100, 400×400, or 600×400 mm) laid in a regular pattern with sand-bedded joints and edge restraint. The volume material across Adelaide. Available in dozens of colours and finishes.

Cost comparison

For a 50sqm courtyard in Adelaide:

• Crazy paving (real stone): $7,000–$11,000 installed
• Crazy paving (concrete substitute): $5,500–$8,500 installed
• Concrete pavers, mid-spec: $3,800–$4,800 installed

Crazy paving is roughly twice the cost of concrete pavers — most of that is labour, not material.

Where each works

Crazy paving suits:

• Heritage homes (especially stone or rendered)
• Adelaide Hills properties
• Mediterranean-style gardens
• Courtyard spaces where the paving is a feature
• Curved or irregular shapes (the chaos hides the curves)

Concrete pavers suit:

• Driveways (modular pavers are wear-rated)
• Large paved areas (set-up costs amortise better)
• Pool surrounds
• Modern-design homes
• Sites where speed of install matters

Lifespan and durability

Crazy paving (real stone): 30-50 years easily. The mortar joints can crack and need re-pointing every 15-20 years.

Concrete pavers: 25-40 years for the volume product. Higher-spec pavers last longer; the bedding and edge restraint determine more than the paver itself.

Repair difficulty

Concrete pavers are easy: lift the damaged paver, re-set on fresh sand, replace.

Crazy paving is hard: cracking a single piece often means breaking out a section, sourcing matching stone, re-mortaring. After 20 years, exact-match stone is hard to source.

Joints and weeds

Mortared joints in crazy paving don’t grow weeds easily but can crack in winters with ground movement.

Sand-jointed concrete pavers grow weeds in the joints unless you maintain them. Polymeric sand jointing reduces this but isn’t permanent. Joint maintenance every 3-5 years.

Drainage

Concrete pavers drain through the joints — water passes through into the sand bed and away. Crazy paving with mortared joints sheds water like a slab — it needs proper falls and may need surface drains.

Common mistakes

• Crazy paving on a poor base. Mortared joints stress when the base moves. A proper crushed-rock subbase is essential — more important than for sand-jointed pavers.
• Concrete pavers without edge restraint. Pavers walk over time. Concrete kerb or hidden steel along edges.
• Wrong sealant. Some natural stones need sealing (sandstone, limestone). Some don’t (granite, bluestone). Seal the wrong stone and you trap moisture.

Maintenance

Crazy paving: pressure-wash every 2-3 years. Re-point cracked mortar joints every 15-20 years. Reseal natural stone every 5-7 years.

Concrete pavers: weed and re-sand joints every 3-5 years. Pressure-wash every 1-2 years. Optional sealing for stain resistance.
