WHAT YOU NEED?
- wooden pegs
- spirit level
- levelling board or vibrating plate
- paving slabs
- building sand and cement, or ready-made mortar mix
- lump hammer
- pointing trowel
2. Lay a 10cm layer of hardcore using wooden pegs as a depth marker. If your patio is against your house it will need to be angled slightly so that water runs away from the building. Use the pegs and a spirit level to guide you in creating this slight slope. Compact the hardcore using a board or a vibrating plate.
3. Lay the slabs down to check you’re happy with the arrangement. Start from the house or a wall or fence if there is one.
4. Make a mortar mix from five parts building sand to one part cement; or use ready-made mortar mix and follow the manufacturer’s instructions. Create a bed of mortar 5 to 8cm deep and lay slabs on it; leaving 1cm gaps in between for grouting. Tap down the slabs with a lump hammer. Check with a spirit level as you go to ensure the slabs are level or maintaining the fall away from the house. Leave the mortar to set for at least 24 hours or a few days.
5. Fill in the spaces between the slabs with a mix of three parts building sand to one part cement (or your ready-made mix) using a pointing trowel. If you get any of the mix on the slabs; remove it. Allow to dry for a few days.
