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.

Patios do not require lots of maintenance. They will only need occasional cleaning to make sure that the material keeps its original appearance. It's always best to clean your patio with a pressure washer and occasionally tap each slab or brick just to check the sand underneath hasn't washed away.

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.
