Follow our simple steps on how to lay a garden patio, below.
You Will Need
Cement mixer, optional
Plank of wood
Lay the hardcore
Clear the area you’ve chosen for your patio to a depth of 15cm to allow room for the hardcore, mortar and paving slabs. Lay 5cm – 8cms of hardcore, using a rake to distribute it and even out any bumps.
Compact the hardcore
Compacting the hardcore
Use a wacker plate to compact and level the hardcore. It’s not essential, but stops the rubble moving around while you lay the slabs, making the base solid.
Level the patio
Levelling the patio
Hammer wooden pegs into the ground – they need to be at the same height to mark the level surface of the patio. Make sure they’re level with any existing paving and manhole covers. Position several over the patio site to work with, using a spirit level to ensure they’re even.
Arrange the patio slabs
Arranging the patio slabs
For a random design, place several slabs on the ground to help you decide which shapes interlock well together. Alternatively, cut out pieces of paper to represent scaled-down slabs and work out a design on your scale plan.
Lay the patio slabs
Laying patio slabs
Make a mortar mix – five parts building sand to one part cement. If you’re laying a small patio, do this in a wheelbarrow, for larger areas it’s worth hiring an electric cement mixer. Lay slabs on a bed of mortar 5cm – 8cm deep, tapping down firmly with a rubber mallet or pressing down with your hands.
Level the slabs
Levelling the slabs
You need to leave a 1cm gap between each slab, which you’ll fill in later with mortar. As you progress, use your spirit level or a plank of wood to ensure the slabs are level with the pegs you banged into the ground earlier.
Edge the patio
Edging the patio
Edge the patio with paviours laid on a 5cm – 8cm layer of mortar, butting them closely together. For a neat fit, use a hammer and bolster chisel to break paviours where necessary.
Wash the patio slabs
Washing the patio slabs
Wash down the slabs when you’ve finished, making sure you remove any splattered mortar before it hardens and stains the paving.
Fill in the gaps in the patio
Filling in the gaps in the patio
Fill the gaps between the paving slabs using a pointing trowel and the same mortar mix as before. Try not to get mortar on the slab surfaces as this will stain if allowed to set.
Patio on a gradient
If the patio is next to the house, include a slight gradient away from the house when laying the slabs, so that rainwater simply runs off into an area where it can be soaked up.
