Beginners’ guide: How to lay paving slabs

Paving Preparation:

• Measure and plan your project carefully.
• Order the right amount of stone.
• Consider renting equipment like a mini excavator for larger areas to save time.
• Ensure good drainage to avoid water pooling on the surface.
• Mark out your area using a tape measure or string.
• Dig down about 15 cm (6 inches) deep.

 

The Sub-Base:

• Spread crushed concrete evenly over the area.
• Compact it thoroughly with a vibrating plate machine.
• Aim for a thickness of at least 7.5 cm (3 inches).

 

Preparing A Cement Mix:

• Wear safety gloves.
• Mix 4 or 5 parts building sand, 1 part cement, and water until smooth.
• Apply a 5 cm (2 inches) thick perimeter course of mortar to the sub-base.

 

Laying the Paving Slabs:

• Lift stones properly to avoid back strain.
• Get help for heavy stones and wear steel-toe boots.
• Position each stone flat on the mortar.
• Use a rubber mallet to tap stones to the right level and slope.
• Check for consistent gaps and edge levels.
• Let it set for 24-48 hours.

 

Final Touches and Sealing:

• Fill gaps between slabs with jointing compound.
• Spread the compound using a trowel and brush.
• Make it smooth for a neat look.
• Optionally, apply a sealer to protect the paving from weather.

Allow any efflorescence to develop before sealing to avoid trapping it in the stone. If there’s no sign after 6-8 weeks, you should be okay to seal.
