The Paver Base System

A proper paver installation has four layers: compacted subgrade (native soil, compacted), gravel base (4-6 inches of compacted crushed stone), bedding sand (1 inch of coarse sand, screeded level), and pavers (set in pattern, compacted with plate compactor). Skipping the base is the #1 reason paver patios fail — they shift, settle, and grow weeds within 1-2 years.

Paver Patterns and Waste

Running bond (brick pattern): classic look, 5% waste. Herringbone 90°: strongest interlock, ideal for driveways, 10% waste. Herringbone 45°: most visually striking, 15% waste (most cuts at edges). Basket weave: traditional, easy to lay, 5% waste. Herringbone patterns resist shifting under traffic better than other patterns — recommended for any area with vehicle or heavy foot traffic.

⚡ CalcWolf Insight

A plate compactor ($60-80/day rental) is essential for pavers. Compact the gravel base in 2-inch lifts (not all at once). After setting all pavers, run the plate compactor over the entire surface to lock them into the sand bed. Without compaction, pavers will shift and settle unevenly.

Frequently asked questions
How much does a paver patio cost per square foot?
DIY materials only: $4-8/sqft (pavers + base + sand). Professional installation: $10-25/sqft depending on paver type and site conditions. A 15×12 (180 sqft) patio: $720-1,440 DIY or $1,800-4,500 professional.
Do I need polymeric sand?
Yes. Polymeric sand hardens between pavers after wetting, preventing weed growth and ant intrusion while locking pavers together. Regular sand washes out with rain. Polymeric sand costs $20-30 per 50-lb bag and covers about 40 sq ft.
