A surface of concrete pavers can look level on installation day and still settle early when the ground below moves. Proper paver base compaction gives patios, walkways, and driveways the support they need through Southwest Florida rain, sandy soil, and daily vehicle traffic.The visible pavers matter, but long-term performance depends on base preparation and the compacted layers below. Water control, correct material, and mechanical compaction create a consistent foundation for interlocking pavers.
Key Takeaways
Use an aggregate base made from angular crushed stone, such as crushed limestone, limerock, or dense graded base, instead of native sand for patios, walkways, and driveways.
Install aggregate in controlled 2- to 4-inch lifts and use mechanical compaction on every lift before adding more material.
Plan the slope before excavation. A 1% to 2% fall away from buildings is a practical target for many projects.
Keep bedding sand thin, usually about 1 inch, and don’t compact it before the pavers are set.
Stop work during base preparation if the subgrade is wet, soft, or pumping water under equipment.
Secure edge restraints and fill the joints with joint sand after final surface compaction.
