Installing Pavers Over Existing Concrete

Once the concrete has dried border pavers will be glued down using mortar or a construction adhesive.

Installing pavers over existing concrete.

Installing pavers over concrete can help to prevent problems like these. Use a quality professional masonry adhesive for this application. For instance installing pavers over concrete for a pool deck may be a risky proposition because if the pool pavers are too high they may create a tripping hazard near the pool or may make people cut themselves when they are entering or exiting the area. According to several paver manufacturers paving blocks can be installed on top of concrete without mortar if you first lay down a 1 2 to 1 bed of coarse sand.

Glue down the last border patio blocks. Start laying the border course along your home butting the pavers against the building and bonding them generously to your existing concrete patio. Work in small areas to ensure the mortar stays wet for paver application. The border course will be the only pavers necessary to bond to the existing concrete.

Choose a pavers contractor who provides a strong foundation and high quality materials for your pavers project. The process is nearly identical to laying a paver patio over ground. The existing concrete pad must slope away min 1 of fall for 8 feet of run from any structures to ensure drainage. Lay the field pavers over concrete as you would on any paver patio.

The most important tip you must create a drainage layer 1 of bedding sand below the pavers. The right foundation extends the life of the paver project. Because of their smaller size individual pavers are less prone to cracking as the material expands and contracts during temperature fluctuations. Place 1 2 of latex modified mortar underneath each paver adhering it to the concrete.

The best process involves digging down 6 to 8 feet beneath the ground. The paver installation process will involve the removal and replacement of unsuitable soil with materials like geofabric that help make the pavers work better and last longer. In doing so you allow for any water to drain away from pavers and off of the concrete slab remember the thinner the bedding layer the greater risk of damaging the pavers. Clean the concrete surface of all dirt oil and debris.

Scrape away the excess sand and cut off the excess landscape fabric with a utility knife. Before installing pavers over concrete the surface is cleaned with pressure washer to remove any dirt or debris.
