Final Compaction and Joint Filling

What happens here

Once all pavers are laid and initially adjusted, the entire driveway surface needs to be compacted using a vibratory plate compactor. This step achieves the final interlock of the pavers, locking them together and embedding them firmly into the bedding layer. After compaction, fine-grained joint sand (often polymeric sand) is spread over the surface and swept into all the paver joints. The surface is then wetted, which activates the polymers in the sand, causing it to harden and create a flexible, durable bond that helps prevent weed growth, insect infestation, and erosion of the joint material.

Goal: Lock pavers in place and fill joints for stability and longevity
