Paving a patio

My parents' patio had sunk. It wasn’t from the usual sources like incessant rain or snow on the roof, but rather from paver blocks that had been laid over decades. To fix the problem, we first had to figure out how to get the patio off the ground, which we did using cinder blocks.Before even thinking of laying paving slabs, you need to prepare your patio area. If you’re upgrading paving slabs that are already in place, dig these up before beginning. Dig a depth of around 150mm across the whole area, making sure the soil is evenly compacted. Then tip in the sub-base, raking it into a consistent depth of 100mm. Make sure it’s smooth, flat and firm.If you're looking to make a small change to your patio and update what is currently there, then here is the guide you need. Here’s how to lay a patio for beginners in 6 easy steps.


Before you can start laying patio slabs, you need to dampen them so they don’t dry out your concrete too quickly. Then, lower your first paving slab into position. Lay it into the concrete mix and gently tap it with a rubber mallet so it’s fixed in place. Ideally it wants to sit 15mm in the mortar. Repeat this process, leaving a 10-15mm gap between each paving slab, until your patio is covered. Once you’ve laid your patio, spray the whole area with water until it’s completely saturated, and leave it to set for at least 24 hours.

Before you start excavating the sub-base area, use a hired cable avoidance tool (CAT) to check for any underground pipes or cables for gas, water, electricity, telephone or drainage services. Pipes and cables should be buried a minimum of 450mm below the surface, but you can't always be certain that this is the case - especially with older properties. If you find buried pipes or cables, you can employ a professional to relocate these, or consider an alternative location for your patio.Lay out the paving slabs in the desired pattern, either where you plan to build your patio or on a clear, flat area of lawn. Allow for your preferred joint size between each slab. Mark out the area for the sub-base using wooden pegs and a builders line. Ideally add an extra 5 to 10centimetres (cm) to every edge of the patio measurement. This will make the sub-base slightly bigger than the finished patio giving it a more secure foundation.

Although the fall has already been set in the sub-base, it’s important to run a set of builders lines marking the perimeter of the patio and the top edges of the paving slabs. This will help you maintain the correct slope when you lay the sl.Take four wooden pegs and mark with a line 115mm from the top. This allows 65mm for the thickness of the paving slab plus 50mm of bedding mortar underneath. (Source:abs.

Position the wooden pegs so they're just outside the project area, but aligned with the borders of the final paved area.For some paving projects you'll need to cut paving slabs. An angle grinder fitted with a stone-cutting disc will make light work of the cuts. Mark the cutting line in pencil on both the surface and edges of the slab and use the angle grinder to follow this until you have a clean Paving slabs are bedded in a mortar mix with four parts sharp sand to one part cement. Measure your quantities using a shovel or a bucket - for example, four buckets of sand for every one bucket of cement.

The colouring is added to a dry jointing mix, following the instructions on the packaging. Take care to use the same dosage if mixing more than one batch, to keep a consistent colour.
