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. 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. To install pavers over concrete using a mortar set application. Installing pavers over concrete can help to prevent problems like these.

Clean the concrete surface of all dirt oil and debris. The right foundation extends the life of the paver project. Place 1 2 of latex modified mortar underneath each paver adhering it to the concrete. Work in small areas to ensure the mortar stays wet for paver application.

The most important tip you must create a drainage layer 1 of bedding sand below the pavers. The best process involves digging down 6 to 8 feet beneath the ground.

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. Lay the field pavers over concrete as you would on any paver patio. The process is nearly identical to laying a paver patio over ground.
