Patio Floor Materials
Having a patio really is a great way to make the most of an outdoor space. And they are not just a summer pleasantry too, with patio heaters and covered outdoor tables there’s no reason not to enjoy it all year round. Here you can find out everything about the patio floor materials.
Sketch out the project on graph paper first to minimize cuts, stagger the joints, and estimate how much material you’ll need. Prepare all the materials like bluestone, hardcore, builder’s level, mortar mix, lump hummer etc. You can also rent a skid-steer loader to clear away debris and dig the patio base. Also, you should locate and mark any in-ground gas, electric, water or phone lines – spray-painting the ground is the best option.
Preparing patio basement
With the help of pegs and strings mark out the position of your patio using. It’s easiest to adjust the size of the patio so that you don’t have to cut any of the slabs. Dig out to a depth of 15cm unless your patio is against the house in which case you’ll need to go an extra 15cm below the level of the damp-proof course.
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.
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.
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.
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.
