How to lay a patio - step by step
Preparation
We chose to use slate paving, but the choice of materials is endless (from sandstone to York stone to concrete), whatever you go for - the method is identical. The key to success lies in the preparation, if you get the ground even at the start and cover it with hardcore rubble (you'll find this at most builders' merchants sold as MOT) you won't go wrong.
We recommend you use a wacker plate to level the ground. It may also help to draw a scale plan of your patio so you can work out the shape and pattern of the slabs, along with the exact amount of materials you will need.
Materials
- Hardcore material, MOT type 1 (£39 at Wickes)
- Building sand (£39 at Wickes)
- Cement (£5.48 for a 25kg bag at Wickes)
- Natural slate paving
- Paviours from Bbradstone.comTools
Shovel, rake, wheelbarrow, wooden level pegs, hammer, spirit level, plank of wood, wacker plate, cement mixer, rubber mallet, bolster chisel, pointing trowel. For tool hire, try www.hss.co.uk
Prepare the ground
First, remove any turf, plants or paving to a depth of about 15cm (6in) to allow room for the hardcore, mortar and paving slabs.
Now barrow in a 5-8cm (2-3in) layer of hardcore. Use a rake to distribute it, and even out any bumps. The rubble will form a good solid base for the patio and will stop you, and the site, getting muddy if it rains during construction.

Secure the base
Use a wacker plate to compact and level the hardcore. Although not essential, this stops the rubble moving around while you lay the slabs, making the base solid.

Plan the level
Wooden pegs hammered into the ground to the same height will mark the level surface of the patio, and you need to make sure they are level with any existing paving and manhole covers. Position several all over the patio site for you to work with, using a spirit level to ensure they are all even.
If the patio is next to the house, it's important to include a slight gradient away from the building so that rainwater simply runs off into an area where it can be soaked up. Again, use a spirit level to help create a steady gradient.

Plan slab placement
If you want a patio with a random design, place several slabs on the ground to work out which shapes work and interlock well together. Alternatively, cut out pieces of paper to represent scaled-down slabs and work out a design on your scale plan.

Mix the mortar
Make a mortar mix of five parts building sand to one part cement. If you're only laying a small patio, you could do the mixing in a wheelbarrow, although generally it'll be quicker and easier to hire an electric cement mixer (see our tools list). Mix more mortar as and when you need it.

Lay the slabs
Lay each slab on a bed of mortar that's about 5-8cm (2-3in) deep, tapping it down firmly with a rubber mallet or pressing down with your hands.

Ensure slabs are level
You need to leave a 1cm (½in) 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 patio
Edge the patio with paviours, laying them on a 5-8cm (2-3in) layer of mortar, as you did with the slabs. Butt them up together and, for a neat fit, use a hammer and bolster chisel to break paviours where necessary.

Wash it down
At the end of the day, wash down the slabs you've laid, making sure you remove any splattered mortar before it can harden and stain the paving.

Fill the gaps
Fill the gaps between the paving slabs using a pointing trowel and the same mortar mix as you used before. Try not to get mortar on the slab surfaces, as again this will stain if it's allowed to set.
