How To Lay Block Paving

Do you wish to know how to install block paving? We’ve got you covered! Here, you’ll find a useful step by step guide that’ll provide you with all the necessary information to lay a wide range of block paving products available in the market today. You must, however, note that the installation of block paving can be a tricky affair and should not be attempted unless you have undergone a proper training or have a good experience in the field. If otherwise, we’d advise you to leave the task for a reliable block laying professional to guarantee the best results and also avoid making costly mistakes.

lDesign

• Draw up a design to perfectly suits your needs.

• Decide on the type of block as well as colour.

lExcavation

• Use a mini excavator or a JCB ( depending on the size of the job) to excavate the driveway.

• 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.

1. Prepare the sub-baseThe driveway company will excavate, or dig, the existing surface down to a depth of around 200mm. They will remove any debris from the area may place it in a skip or arrange for it to be removed in another way. When they dig down to the sub-base of your previous driveway, they will assess how much hardcore they need and arrange for that to be delivered to the site. They will then spread the hardcore across the sub-base to create a level surface to pour the concrete on. Most good contractors will apply a gel to any walls and doors to protect them from concrete splashes. They will also add any gulley tops, manhole covers or shuttering that’s required.
2. Installation and imprintingNext, the tradespeople will have the concrete either poured from a large mixer vehicle or barrow it in from a mixer and pour onto the surface. They level it with rakes, then add a colour surface hardener in a colour of your choice. This will give the driveway its permanent colour. They will then wait until the concrete has hardened to the correct consistency for imprinting the pattern, then will use special tools and stencils to make the pattern that you asked for. They will then spread a colour powder called a release agent over the surface, and leave to dry for 1 to 2 days depending on the weather conditions.
3. CleaningWhen the contractors return, they will add crack control cuts into the concrete. This is important because concrete expands and contracts in the heat, so there needs to be some give to stop any larger cracks from forming. Then everything is power washed clean, and a chemical wash is also used on the concrete to ensure it’s completely dust-free. The installers will ensure all your walls and doors are clean, which will hopefully be an easy job if they used wall gel.
4. SealingThe final step is to seal the driveway. There needs to have been at least two dry days before the tradespeople can do it, so you might find it’s best to have your pattern imprinted driveway installed in the summer. The contractors will blow any debris away from the surface and dry any damp areas where necessary. They will then add an anti-slip agent to the sealant and brush it on. It’s best to not walk or drive onto your new concrete driveway for about 4 days after sealing to allow everything to set. But after that, you’re ready to use your new driveway!

• What colour you choose
• What pattern you choose

• Where you live
• How big you want your driveway to be
• What colour or design you would like
• Whether any additional work will need to be completed to prepare the area for the driveway

Driveway work is usually done in the warmer half of the year. This is partly to avoid bad weather. If you want to get ahead and avoid waiting for a contractor to be free, you should try getting in touch with a professional in the early spring so a date can be booked for install as soon as practically possible.

No, pattern imprinted concrete shouldn’t be slippery. Most good driveway installers will add a special anti-slip agent to the sealant before they brush it onto your driveway, so it will stop it from being slippery.

It’s important to ask a driveway company how they will seal your driveway when you get a quote from them. If an untrustworthy company seals your driveway badly, it can cause a thick and extremely slippery surface, so it’s vital that you ask any contractor what their procedure is before you engage them.

It’s also important to remember that pattern imprinted concrete isn’t a ‘non-slip’ surface – it’s just not slippery. You could still slip over on a concrete driveway, just like you could on tarmac or a block paved driveway. Also, once you’ve walked and driven over your driveway for a few months, its skid and slip resistance will increase as it weathers and builds up tiny specs of dirt on it. Pattern imprinted concrete is often used in high footfall areas in places like shops, fast food restaurants and theme parks, so if there was a significant slip risk these businesses wouldn’t use it.

You might think that you could ask your contractor not to seal the driveway to make it less slippery, but it could actually do the opposite. By sealing pattern imprinted concrete, it means that moss and algae is much less likely to grow, which can be extremely slippery to walk on if it’s left to its own devices. If moss does form on your driveway, the sealed surface is much easier to clean as you can simply pressure wash it away; this is not as easy to do on a non-sealed surface.

Whether you think resin bound driveways are expensive or not will depend on your perception. While resin bound driveways are the most expensive up front, they should last much longer than other types of driveway. You should expect a resin bound driveway to last at least 25 years, if not longer, while a concrete or asphalt driveway may last between 15-20 years. A pattern imprinted driveway may last even less time due to the maintenance required to keep them looking pristine.

It’s also worth considering that resin bound driveways are good permeable surfaces, so will drain well and keep water from pooling around your property. This will keep your property maintenance costs down, since pooling water or flooding around your home could cause damp in your walls which is a very expensive problem to fix.

Resin bound driveways are by far the most attractive type of driveway to have. There are no loose stones to sweep up, no weeds to pull out from the gaps, and there’s no extensive power washing required to keep them looking good. If you want a driveway that gives your home true kerb appeal and you value your time, resin bound driveways don’t seem that expensive.

The other factor that can make resin bonded driveways less expensive is that sometimes you can lay them on top of the existing surface. For example, if you already have a concrete or asphalt driveway that is in good condition with no large cracks, a driveway contractor may be able to lay the resin and aggregate mix straight over the top, which will cost much less money than if you have to dig up the existing driveway and start from scratch.
