A solid foundation is key to a paver installation. Numerous problems can surface in a patio or other paver element if the proper foundation isn’t laid. Here are three paver problems that can manifest when the installation isn’t on point. These problems don’t show up within a few days of installation; they arise over time.
Uneven pavers are usually the result of not going deep enough when installing. The base needs to be several inches deep and if it’s not deep enough or even enough you’re going to end up with some problems. Another issue can be the type of soil or base below the pavers. If the soil below has a higher density of clay it can hold more water than sandier soils. During the winter the soil can freeze and expand and that can cause some of the pavers to push up and your whole patio, driveway, walkway, to be uneven and even hazardous.
If you have these problems you’re more than likely going to have to entirely remove the pavers and redo the job in order to repair the issue. If this is the case make sure your base is thick enough and don’t use small gravel or gravel dust because it will act much like clay and you’ll have the same problems all over again.
Puddling and Dips
It’s really imperative that when building the base for your installation that you make sure you’re properly compacting the soil. Areas that aren’t compacted will settle over time and can create dips and you can develop a problem with puddling. The can be fixed by pulling out the pavers in the problem area and fixing your base.
Paver Border Is Tipping Over
When you’re installing pavers you need to have edge restraints. Many times DIY jobs can miss a component and proper edge restraints can easily end up being one of those areas that are overlooked. This can also occur when there isn’t sufficient joint sand swept into the paver joints or it’s poorly compacted. This type of problem can usually be fixed by removing the edges and reinstalling with quality edge restraints and finishing off with the appropriate joint sand process.
