Pros and Cons: Installing Pavers Over Concrete

When it comes to laying pavers, we are always looking for shortcuts and money savers to help lower the expense of the project. We all want to have a patio design that is beautiful, but paying to have concrete removed is very expensive, and very hard as well as time consuming if you try to go the DIY route and dispose of it yourself. Many homeowners, encouraged by some contractors, believe that installing pavers over concrete is the best way to save both time and money. But is this really a good idea for the best paver project you can get? This quick paving stones guide will let you know the pros and the cons of installing concrete pavers over an old concrete slab. As you’ll see, the pros are far outweighed by the cons.

PROS

The major pro of installing pavers over concrete is that it saves a bunch of time. Excavating and laying a new aggregate base below the new paver project takes time and money – anywhere from a half a day to three days or more depending on the size and complexity of the job.

For this reason, laying pavers over concrete also saves money. This is because less material will be needed and less labor and time will have to be spent finishing the job.

In addition, contractors like it because it’s simply an easier job to do – they can get in and out much more quickly.

CONS

However, there are many cons to doing this. First, you will be limited in the design of your new driveway, walkway, patio, or other creation. This is because you will have to lay the pavers over the old structure, and thus you’ll be limited to the slab that’s already there.

The other major con is that the strcture below the pavers will not be strong or flexible enough to provide a long-lasting base. When the concrete below cracks, as it inevitably will, the pavers above will also crack and fall apart. What’s the point of installing pavers if you’ll just have to repair or replace them in a few years?
