How to Install Pavers Over Asphalt or Concrete
When installing pavers over existing concrete or asphalt, there are three primary installation options: sand set, bituminous set and mortar set. Outlined below are the details for how to install pavers over concrete or asphalt and the use cases for each of the three installation options.
Important Considerations Before Laying Pavers Over Existing Concrete
One important step in this process is determining whether the existing concrete or asphalt on the job site is in good enough condition to be overlaid. Major defects in the concrete base, like large cracks, will compromise the integrity of the paver installation.
Another important factor is ensuring you allow for proper drainage of the site. Ensure that the concrete base slopes away from any structures and storm water runoff has been accounted for to prevent accelerated erosion of the surrounding area and so that the installation will remain in good condition.
