- Interlocking paving uses concrete blocks laid tight, with sand-filled joints and firm edges, so they lock together and spread load across the surface.
- It is widely used for driveways, parking areas, complexes and paths.

Laying Patterns
Rectangular blocks laid in herringbone lock best under turning vehicles. Stretcher bond suits paths. Zigzag blocks are also laid in herringbone or stretcher bond.
Edge Restraints
Interlocking paving only locks if the edges are held. Without kerbs, a concrete haunch or a wall, the blocks creep outwards and the joints open. Check every quote includes edge restraints.
Where Interlocking Paving Works
- Driveways, in 80mm blocks.
- Parking areas and complex roads.
- Commercial entrances and walkways.
- Patios and paths, in thinner blocks.
Common Problems With Interlocking Paving
- Ruts where the base was too thin.
- Joints opening where edges have failed.
- Weeds where joint sand has washed out.
- Sunken patches over service trenches.
How Interlocking Paving Is Laid
- Base. Excavate, lay and compact the base.
- Edges. Set the kerbs or concrete edge.
- Laying. Screed sand, lay blocks tight, cut edges.
- Lock-up. Brush in joint sand and compact until joints are full.

Frequently Asked Questions
What is the difference between interlocking and bevel pavers?
Zigzag interlocking blocks key together on their shape. Bevel pavers are rectangular and rely on the pattern and jointing to lock.
What thickness do I need for a driveway?
80mm is the norm for vehicles.
Why do interlocking pavers spread?
Usually because the edge restraint is missing or has failed.
Can interlocking paving be lifted and reused?
Yes. Blocks can be lifted for repairs or service work and relaid.
