The Outdoor & General DIY Guide
Laying your own pavers is easier than you think—if you follow the right steps. At Outdoor & General, we recommend the flexible installation method, ideal for patios, paths, courtyards, and even driveways.
This guide walks you through everything you need to know to install pavers the right way, first time
What is the Flexible Method?
The flexible method involves laying pavers on a compacted crushed rock base with a layer of coarse washed sand underneath. Pavers are not fixed with mortar—they’re locked in place with jointing sand and edge restraints.
It’s easy to repair, drains well, and suits most outdoor spaces.
Step 1: Measure & Order Materials
Start by measuring your area and order about 5–10% extra pavers to allow for cuts and waste.
You’ll also need:
- Crushed rock (road base – not crusher dust)
- Bedding sand (washed coarse river sand)
- Jointing sand (silica or polymeric)
- Edge restraints (concrete haunch, steel, or timber)
- Tools: plate compactor, screed rails, straight edge, string lines, rubber mallet, PPE, and a saw or grinder
Step 2: Excavate the Area
Excavate to allow for:
- 75–100mm compacted base for patios and walkways
- 150mm compacted base for driveways
- 20–30mm bedding sand
- Paver thickness (typically 30–60mm)
- Make sure the area has a 1–2% slope away from structures for water runoff.
Step 3: Prepare & Compact the Base
Spread crushed rock evenly in layers. Lightly wet the base to help bind the material, then compact thoroughly with a plate compactor. A solid base is critical for long-term stability.
❌ Do not use crusher dust—it lacks the structure needed to lock in properly.
Step 4: Screed the Bedding Sand
- Lay screed rails and spread coarse washed river sand to a consistent 20–30mm thickness.
Use a straight edge to screed level, then gently remove the rails and fill any gaps. Avoid walking on the screeded sand.
Step 5: Lay the Pavers
- Start from a fixed corner or straight edge. Use string lines to keep rows aligned.
- Leave 3–5mm gaps between pavers
- Blend from multiple pallets for natural colour variation
- Tap each paver gently into place with a rubber mallet
Step 6: Install Edge Restraints
Install edge restraints to hold the layout in place and prevent movement. Use:
- Concrete haunching
- Aluminium or steel edging
- Timber for garden paths
- Ensure the edge is firm and set below paver height.
Step 7: Cut to Fit
Trim pavers as needed using a brick saw or angle grinder. Always wear safety gear when cutting.
Step 8: Fill the Joints
Sweep jointing sand into all gaps.
Use:
- Silica sand for standard applications
- Polymeric sand for better resistance to weeds, ants, and washouts
- Avoid dry cement mixes unless experienced—they can cause permanent staining.
Step 9: Compact & Finish
- Run a plate compactor over the pavers (with a protective mat or carpet under the plate). This beds the pavers into the sand and locks the joints.
- Sweep away excess sand and top up joints if needed.
Final Tips
- Sweep regularly or use a blower to keep the surface clean
- Use pressure washers sparingly (under 1000 psi, fan spray, 50cm distance)
- Reseal every few years in exposed or high-traffic areas
