Overlay pavers uses thin pavers on top of old existing concrete.
Here are 6 reasons why you shouldn’t install Overlay Pavers
Overlay pavers doesn’t provide the 8000 psi strength pavers are known for, making the installation only a paver enhancement, covering the problems underneath.
Overlay Pavers doesn’t include the structural advantage, which consists of compacted soil and compacted gravel, that provides stability to your installation. This makes them solely for a cosmetic enhancement.
Overlay pavers will not fix your existing concrete cracks. Any pre-existing and developing cracks will continue to erode beneath the pavers, ultimately leading to paver separation and erosion.
Access to utilities is very easy with pavers but not with overlay pavers. As both the concrete and pavers need to be removed with overlay pavers, a new installation of concrete and curing will be needed.
Adding a layer of pavers on top of your existing concrete may cause different heights between the pavers to other areas. For example, the driveway and garage area will be different in height.
Adding overlay pavers on uneven concrete sometimes requires more than 1 inch of sand, which is not designed to withhold the weight of pavers causing the sand to sink together with the pavers.
