Anatomy of a Long-Lasting Interlocking Paver Patio

Proper base preparation is 90% of a successful paver installation.

Subgrade Soil: Compacted native soil sloped 1" per 8 ft away from house foundations.
Geotextile Fabric: Woven landscape barrier preventing gravel from sinking into subsoil.
Compacted Gravel Base: 4" to 6" of crushed aggregate (Class 5 road base) compacted in 2" lifts.
Bedding Sand: Exactly 1" of coarse concrete sand screeded smooth (never pre-compacted).
Polymeric Sand: Swept into joints and activated with water to form an insect and weed-proof lock.

Frequently Asked Questions

Stone dust holds water and breaks down into silt under freeze-thaw cycles, causing pavers to shift and sink. Use coarse, washed ASTM C-33 concrete sand.

For standard 4x8 brick pavers with 1/8" joints, one 50 lb bag covers approximately 75 to 90 sq ft.
