Proper edging prevents your tarmac driveway from crumbling at the edges and gives it a professional finish. Brighton homeowners have several kerb options to contain their tarmac and handle the area’s clay soil movement.

Choose concrete kerbs for maximum durability. These precast units resist Brighton’s freeze-thaw cycles and provide excellent edge support for heavy vehicles. Install them on a concrete foundation 150mm deep.

Block paving edges offer flexibility and visual appeal. Use concrete blocks or natural stone to create borders that complement your home’s style. Professional contractors ensure proper installation techniques that allow slight movement without cracking.

Installation Requirements

Dig edge trenches 200mm wide and 250mm deep. The clay soils common in Brighton expand when wet, so proper depth prevents movement damage.

1. Excavate the perimeter to required depth
2. Lay 100mm of compacted hardcore base
3. Pour concrete haunch against the kerb back
4. Allow concrete to cure for 24 hours before laying tarmac

Drainage Considerations

Install channel drains where your driveway meets the road. Brighton’s rainfall requires proper water management to prevent edge erosion and surface damage.

Position kerbs 25mm above the finished tarmac level. This height prevents water pooling whilst allowing easy vehicle access without scraping.

Avoid timber edging for tarmac driveways. Wood rots quickly in Brighton’s damp conditions and provides insufficient support for the tarmac edges. If you’re considering different surface options, concrete driveways also require careful budgeting for proper installation.
