Preparing the Foundation
When it comes to laying block paving, a solid foundation is key to ensuring a durable and long-lasting result. Before you start, make sure you have all the necessary materials, including coarse sand, compacting plate, and of course, those beautiful paving blocks.
The Sub-Base Layer
First things first, you need to create a sturdy sub-base layer. This layer acts as the backbone of your paving project, providing stability and preventing any unwanted movement. Dig down to a depth of at least 10 inches, allowing for 6 inches of hardcore, 2 inches for a sand base, and 2 inches for the blocks themselves.
Once you’ve dug out the area, it’s time to firm down the sub-base layer using a compacting plate. Give it a good old pat-down to ensure a solid and level foundation. Remember, a little extra effort at this stage will go a long way in the longevity of your block paving.
The Bedding Layer
Now that your sub-base layer is in place, it’s time to create the bedding layer for your paving blocks. This is where the coarse, grit sand comes into play. Spread and level the sand on top of the sub-base layer to a depth of around 25-40mm. You can call this sand by various names such as sharp sand, concreting sand, Zone 2, or Class M. Whatever you choose to call it, just make sure it’s coarse and gritty!
To Membrane or Not to Membrane?
One question that often pops up is whether or not to use a membrane between the sub-base and the bedding layer. In most cases, for light-use constructions like driveways, patios, and footpaths, a membrane is not necessary. The sub-base and bedding layer will provide sufficient drainage. However, if you’re dealing with a particularly problematic area, it might be worth considering a membrane for extra peace of mind.
Time to Lay the Blocks
With the foundation in place, it’s finally time to lay those beautiful paving blocks. Start by choosing a pattern or design that suits your taste and the overall aesthetic of your property. There are countless options to choose from, so take your time and get creative!
When laying the blocks, make sure they are placed directly onto the bed of coarse, grit sand. Take care to ensure they are level and evenly spaced. A little bit of attention to detail here will make a big difference in the final result.
As you progress, periodically check that the blocks are still level. Adjust as necessary to maintain a smooth and even surface. Remember, the key to a professional-looking block paving project is precision and consistency.

Finishing Touches
Once all the blocks are in place, it’s time for the finishing touches. Use a compactor plate to gently press the blocks into the sand, ensuring they are securely set. This will help prevent any unwanted movement and keep your block paving looking pristine for years to come.
Finally, give your newly laid block paving a good sweep with a broom to remove any excess sand. This will not only give it a clean and polished appearance but also help the blocks settle into their final position.
Enjoy Your Beautiful Block Paving
Congratulations! You’ve successfully laid your block paving and created a stunning addition to your property. Now all that’s left to do is sit back, relax, and enjoy your beautiful new outdoor space.
Remember, proper preparation and attention to detail are the keys to a successful block paving project. With the right foundation and a little bit of creativity, you can transform any outdoor area into a stylish and functional space that will stand the test of time.
