How to Build a Patio

Building a patio can be generally straight forward if you keep it simple. A common flooring material is pre-cast concrete slabs that are stenciled with a textured pattern. Many of the slabs can be heavy so it will involve some heavy lifting and you may be advised to seek help from a friend or partner to move into place some of the heavier slabs. Generally you should look at spending around three days to complete your task and the first step in building your patio must begin at the planning stage. Also take note of where rain drains off the roof, you will need to think about how to channel the water away.

 

Once you have decided which area of your garden you want to position the patio, you must draw a plan on paper. The plan should be to scale so you may want to use graph paper. Including the full dimensions of your patio and highlight and include all the fixtures like fences, gates, house, sheds, barbecues and preserved lawn areas. Make sure the patio is at least positioned 2.5cm below the home’s damp proof course that is near the base of the walls. This is to avoid heavy rain running into the walls of your home and causing rising damp.

Remember if your patio is to be made up of several different sizes and shapes (crazy paving) you may end up having to cut or chip several of the slabs so a straight border matches like a puzzle piece. It is important to remember to have a slight decline in the patio so that it slopes away from the home. Using a spirit level to check a constant gradient is best. Many local Government regulation do differ slightly regarding slope, however if you allow 0.25cm drop in every 1.5m you will find water will drain enough and sill ok for an almost flat table. The easiest way to measure this is to use a thin clear plastic hose and gravity, all you have to do is measure the difference in drop as water level will be the same at both ends. You could alternatively build a drainage channel within the patio.

Next step involves measuring up. Work out the area of your patio in square meters. If you have purchased a pack of paving slabs it will state on the labeling how much area those packs will cover. If you use various sized paving slabs, as in crazy paving, then you will not need to measure up. Next you mark up the patio using string, pegs and a builder’s square. Draw lines on the pegs which indicate working depth. The working depth indicates the surface of your completed patio.

At this stage we now rake over any divots or bumps and smooth our patio surface. After you have removed any weeds or grass, lay down some mortar over your compact surface.
Use a plastic sheet to mix the bedding cement. Make sure the levels of mortar are even. Then you can lay down your patio slabs. Always start at the corner where the house perimeter starts. Once you have filled the gaps by pointing you let the mortar dry out for a day then clean.
