How To Lay A Block Paving Driveway: Step By Step
The secret behind laying a block paving driveway is preparation. Before starting, you’ll need to prepare by getting the right equipment and materials, planning the design of your driveway, and the excavation. Follow our steps and you’ll be able to lay your own block paving driveway – without paying a hefty bill!
Here’s how to lay a block paving driveway:
- Once you’ve decided on a design to suit your requirements, you’ll need to think about the colour of your paving. Top tip – make sure it doesn’t clash with your house bricks by using our Paver Picker tool below!
- Next, it’s time for excavation. Using your spade, dig out at least 150mm below the damp proof course, with a gradual slope (this helps with the dispersion of any surface water). Make sure to create the slope with a ratio of 1:40 fall across the width of your driveway, and a 1:80 fall over the length.
- Using your cement mixer, combine 1 part cement and 6 parts ballast for the concrete foundation – this should be 100mm thick. Your edge restraint (or kerb) should sit on top of this, using a string line.
- Next, with your rubber mallet and trowel, gently hammer the kerbs in position. Once this is done, haunch the kerbs by adding concrete half way up – on the rear side.
- For the primary layer of support for your paving, you’ll need to add at least 100mm of sub-base aggregate – just make sure to spread evenly within the edges of your drive. To ensure a completely even base, add roughly 50mm each time and then firm using your compacting tool. Pass over the area between 6 and 7 times for so that your blocks will remain in good condition over the years.
- Once all of your drive has been compacted, you’ll need to add a layer of building sand and then use your compacting tool. Cover your drive with a second layer so that the sand reaches the line of the final paving.
- Now it’s time to add the blocks. It’s best to start at the bottom of the slope and work your way up. We’d always recommend starting from a straight line or a right angle for the best quality finish. Lay the blocks approximately 10–15mm above your desired finish level – to avoid a build up of the same colour, use blocks from 3-5 different packs at the same time.
- When you’re laying block paving, you’ll encounter blocks that are too big for the space. This is when you’ll need your block splitter to cut the blocks to size – just try not to cut a block smaller than a third of its original size.
- You’re nearly there now! Once you’re finished laying, sweep the driveway to remove any leftover debris that could be on the blocks. Next, apply a layer of building sand so that it falls down in between the empty spaces, then compact again and repeat this process until all the joints are full of sand.
And there you have it! Now you know how to lay a block paving driveway, so you should be feeling ready to give it a go yourself. Just refer back to our steps if you need a little help along the way. Make sure you have everything you need for paving and driveways before you start.
