Steps to Laying Your Concrete Patio

 

1. Decide on the Location and Design

• Location: Choose a shaded or private spot as desired.
• Design: While curved designs look beautiful, square or rectangular shapes are easier to lay.
• Purpose: Determine if the patio will be for entertaining, an outdoor kitchen, or a walkway.
• Mark the Area: Use string lines and pegs to outline the patio, ensuring proportions fit well with your garden and house.

 

2. Excavation

• Dig the Bed: Work slightly outside your marked area, digging a 105mm-deep bed.
• Surface Level: Ensure the finished surface level is at least 150mm (two house bricks) below any adjacent damp-proof course.

 

3. Laying the Base

• Sub-base: Lay a sub-base of hardcore or crushed stone to provide a stable foundation.

 

4. Mixing the Mortar

• Mix Ratio: Use a ratio of four parts sand to one part cement.
• Consistency: Mix until you achieve a smooth, workable consistency.
• Apply Mortar: Spread an even layer of mortar on the prepared base in sections.

 

5. Laying the Concrete Paving Slabs

• Start from a Corner: Begin in one corner, working your way across.
• Position Slabs: Gently tap slabs into place with a rubber mallet, ensuring they are level and evenly spaced.
• Check Level: Regularly check with a spirit level for a consistent surface.

 

6. Finishing Touches

• Drying Time: Allow the mortar to dry for at least 24 hours.
• Fill Gaps: Fill gaps between slabs with jointing compound or sand to enhance appearance and secure slabs.

 

Maintenance Tips

• Cleaning: Periodically clean with a mild detergent and water.
• Avoid Chemicals: Steer clear of harsh chemicals that can damage the surface.
