Can You Lay Block Paving On Top Of Concrete?

The replacement or improvement of your driveway is unarguably one of the most expensive projects you can undertake in the exterior of your home. When done by a true professional the results can be impressive and visually appealing, however you’d have to pay huge bucks to have this done. This is exactly the situation with block paving as it is not only time consuming, but also a lot more expensive when compared to other types of driveway.

A large chuck of this cost is associated with the removal of the existing driveway. So assuming your old driveway is concrete, can you simply pave over the existing concrete? If yes, will it save you money? The simple and short answer is yes. It’s in fact advisable to pave over concrete as this will not only add around 20% to your home’s value, but also make it look a lot more attractive and pleasing to the eye.

However, there are some problems associated with block paving over concrete. It may be better to remove the concrete in situations whereby the base is substandard. For instance, if the ground underneath the concrete is failing, there’ll most definitely be problems.

Also, there’ll be some issues with settling (not even the cracks). If your concrete is dropping little amounts every year, these can affect the blocks and ultimately lead to dropping of some sections of the block paving in such a way that they’ll no longer be on the same level as the other blocks. Giving a rise to the possibility of drainage issues, tripping hazard and lots more.

Other issues that may crop up can be triggered as a result of using the wrong size block height as well as totally ignoring or overlooking the undulations of the concrete.

Driveways usually sink because they haven’t been laid properly. They may not have been dug deep enough, or the installer might not have used the right materials. This will need to be corrected at the earliest opportunity, although in extreme cases, the driveway may need to be completly be relaid.

1. Prepare the base If you want your resin bound driveway to last a long time, you need to ensure that you prepare the base properly. Remove any block paving, grass or soil and dig down until you hit solid ground. Lay a sub-base of asphalt for good permeability. If you’re laying over the top of your current driveway, make sure that all cracks are increased into a ‘v’ shape with a saw and ensure the surface is dry and weed-free.
2. Mix the resin You must follow the instructions on the materials you have to the letter if you want the curing process to work. Usually batches come in ‘Part A’ and ‘Part B’. Keep the resin container secure and on a protective surface to avoid splashing, then mix Part A for 10-20 seconds at a slow speed with a helical bladed mixer. Add Part B and mix thoroughly at a slow speed for about 2 minutes until it’s blended together.
3. Mix the dried aggregates and sand with the resin Place a quarter of the aggregates into a mixer, then add the pre-mixed resin and start a stopwatch. You should then add the rest of the aggregates before slowly adding the sand. When you’re happy with that mix, stop the stopwatch. That time is the time that you need to spend mixing any other resin and aggregates to avoid colour variation.
4. Lay the mix on the surface Transfer the mix to the work area then plan a laying route. When the mix is laid out, use a very clean trowel to spread the mix. Clean it regularly during the process to avoid dragging aggregates out of place. Once the aggregates stop moving in a fluid movement and become solid, stop trowelling. Then you can polish the surface to give it an attractive shine.

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.
