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.
