• Identify and mark out the area to be excavated.

• Dug out the area until you reach a suitable level

• Ensure that the proposed finish level is 150mm underneath the damp proof course in any of the adjoining building’s brick.

lEdge Restraints

• Build a 100mm depth-thick concrete foundation with the help of a concrete mixer, 1 part cement and 6 parts ballast.

• Position the kerb unit on top of the level with a string line and spirit level.

• Use a trowel and rubber mallet to mortar the kerb unit to the foundation.

• Haunch the back of the kerb units in such a way that the concrete reach half way up the kerb’s rear.

lSubbase

• Put the crushed concrete in the edge restraints and ensure it’s at the desired level of 50mm.

• Use a vibrating plate to compact and level

lScreeding

• Apply a layer of sharp sand (to 50mm depth) and campact it using a vibrating plate.

• Apply second layer of sharp sand (to 20mm depth) on top of the first layer.

• Level the second layer to the correct falls.

lInstallation Of Paving

• Lay the block paving starting from the bottom of a slope.

• Ensure the blocks are placed at about 10mm to 15mm above the required finish level.

• Make sure the blocks used are between 3-5 packs as you proceed with your desired pattern. You may need to cut smaller block pieces to fill smaller gaps.

lFinishing Touches

• Clear out the area to ensure no debris is left on the blocks.

• Put kiln dried sand and brush across the whole of the area, ensuring the sands falls between the blocks’ joints.

• Compact the drive with the vibrating plate.

• Brush more kiln dried sand over the area and compact again

• Repeat the process until the joints are full of sand.

Have you decided to install block paving and wondering what the best sand to be applied to the joints is in order to achieve a perfect job? Well, you’re at the right place! This is one of the most frequently asked questions when it comes to block paving and we seek to give you a reliable solution once and for all.

The best sand for block paving is a kiln-dried sand. It’s an extremely fine sand which has been dried in a kiln to get rid of all the water before it’s incorporated to achieve the best results. Therefore, the sand contains no moisture and is commonly used to fill the joints of block paving to keep the paving’s structure rigid and strong. It also goes a long way to prevent the ingress of water while stopping the paving from moving and becoming loose. The major reason why the paving sand must be dried is to allow it flow easily into the joints as well as the block paving’s gaps. As result of this smooth flowing to the bottom of the joints, there will be no sand sticking to the sides of the pavers.

Another major reason why kiln-dried sand is commonly applied to the block paving’s joints is to prevent water from penetrating the paved area. It also tightens the individual pavers together to prevent from moving and becoming loose. In the event whereby you happen to leave the joints of your block paving without kiln dried sand, it’s highly likely that they’ll sink as a result of water penetration and the blocks will become very loose. After washing block paving, it’s very important to also replace any sand washed off in the process once the paving is dried to prevent water ingress into the joints.

If you want to give your concrete paving slabs a new lease of life, it’s possible to paint them. This is a great option if your slabs are looking tired or you want a new look, but you don’t want to invest in new paving.

Before you go ahead, you need to make sure that your slab paving is clean and dry. And if it’s been sealed, you’ll need to strip this off. Make sure you get a paint that’s specifically designed for the job so you get the best results.

There’s no doubt that weeds coming through your block paving can be unsightly and annoying. But, it’s relatively easy to get rid of weeds that are growing in the joints between your block paving. To start, pull out the larger weeds, and then you can use a pressure washer or firm bristled brush to remove the smaller weeds and debris from the joints in your block paving. It’s best to then refill the joints with additional sand to ensure your block paving remains level. Regularly brushing your block paving and treating with weed killer will help to prevent the weeds from reoccurring.

A resin bound driveway is made from resin and aggregates that are mixed together to create a smooth, flat surface. They’re often called ‘stone carpets’ because they offer a decorative finish that is durable and requires very little maintenance. It has lots of little gaps that allow water to drain into the ground, which means that you won’t get pooling or flooding around your property.

You can choose from lots of different colours and types of aggregate (stones) so that your resin bound driveway complements your property. Most contractors recommend choosing a darker aggregate because they are more resistant to the sun, but if you choose a good UV-resistant resin you should be able to have a lighter stone that doesn’t get too bleached by the sun.

To lay a resin bound driveway, resin and aggregates are mixed in a forced action mixer to create a mixture that a tradesperson will then pour and trowel onto a prepared base. It will become smooth once it’s cured, and the stones will all be contained, so you won’t have to spend time sweeping gravel back onto your driveway. The only maintenance that’s needed is to wash it with soapy water every now and again and sweep away any debris. Just make sure you don’t use chemicals or oils, as this might damage the coating.

While many professionals will recommend a pressure washer to clean block paving, it’s possible to clean your paving without one – just scrub the affected areas with a firm bristled brush and use plenty of soap. Then, rinse off the area with clean water.
