Sephaku Cement shares top tips on how to build a DIY Concrete patio just in time for summer. It’s not just summer bodies that are made in winter; we’re just a few months away from warmer weather, and the ideal time to upgrade you current patio and outdoor entertainment area is during the last legs of winter. 

Outdoor patios create the perfect meeting space for friends and family to convene in a relaxed setting for glorious summer get-togethers day or night. Update your current outdoor entertainment area with a simple DIY installation made possible with a variety of concrete slab options.

Concrete slabs such as flagstone are available in an array of finishes, colours and even design options that result in a one of a kind look in any home. Large or small, concrete slabs are easy to work with and fairly simple to install and offer a lasting result when following a few tips from tried and tested patio installations.  

To follow, see Sephaku Cement’s Top Tips to installing concrete slabs on your patio.

  • Tip 1: 
    Be sure that the concrete slabs are well supported by a stable and sturdy foundation and that they are installed at a slight drop away from the house or surrounding buildings. The ideal would be a 1:40 or 25mm per meter drop.
  • Tip 2: 
    Once you have settled on the size and design of concrete slab, mark the patio’s area and where you plan on placing a more intricate design, it’s best advised to draw the design to scale in preparation of the placement of the slabs or even lay the flagstone slabs out on the ground first to make sure the design fits together to create the desired end result. 
  • Tip 3: 
    When digging out the patios surface area, always prepare the area slightly larger than the end results measurements. Also make sure that the depth of the foundation is able to cater for the subgrade, bedding and the slabs themselves resulting in the patio running flush to the surrounding grounds. Make sure to compact the base before adding the bedding layer using a Plate Compactor which will ensure a steadfast installation that does not shift or rock under foot.
  • Tip 4:  
    When placing the flagstone slabs, this should be done on top of a 25 to 40mm bed of river sand ideally infused with about 10% of dry cement powder. For optimal installation, lightly wet the surface of the bedding and the underside of the concrete slabs which will activate the cement and ensure that the slabs are securely fixed in place. Tap each slab down as they are placed using a rubber mallet or wooden hammer to ensure the level and uniform placement of each.
  • Tip 5:  
    Allow a few days for the slabs to set in place. To ensure that these are well supported and do not rock or wobble when stepped on; fill the gabs between each slab with a premix of mortar. Be sure to brush off any loose material or mortar mix from the surface of the slabs to avoid unsightly blemishes or discolouration. Cover the slabs with polythene sheeting for up to 2 days to finish the job. Wait 21 days before any coating is placed on slabs if required.
