How to Calculate Pavers and Base Materials
Installing interlocking concrete pavers creates an attractive, durable hardscape that outlasts poured concrete when built upon a properly compacted foundation. Every installation requires three distinct material layers: the crushed rock sub-base, the bedding sand layer, and the pavers themselves filled with polymeric sand.
Paver Count Formula
Common Paver Laying Patterns & Interlock Strengths
The layout pattern affects both the aesthetic appeal and structural load distribution of your patio or driveway:
Herringbone (45° or 90°)
Highest Interlock Strength. Essential for vehicular driveways because the diagonal joint lines resist tire turning and horizontal creep.
Running Bond
Easiest Installation. Pavers are laid in parallel courses with staggered joints. Simple to cut along edges; ideal for straight walkways.
Basketweave
Classic Colonial Style. Pairs of rectangular pavers alternate horizontally and vertically. Requires minimal edge cutting for square patios.
Stacked Bond
Modern Minimalist. Continuous joints run both horizontally and vertically. Lowest interlock strength; strictly recommended for light pedestrian use.
Cross-Section Anatomy of a Long-Lasting Paver Patio
- Compacted Native Subgrade: Excavated 7 to 9 inches below grade, sloped at 1/4" per foot away from the house, and compacted using a mechanical plate compactor.
- Geotextile Separation Fabric: Heavy-duty non-woven landscape fabric placed between the soil and crushed stone to prevent base rock from sinking into the mud.
- Crushed Aggregate Sub-Base (4" to 8"): 3/4" minus dense grade crushed limestone or quarry process stone compacted in 2-inch lifts.
- Coarse Concrete Bedding Sand (1"): ASTM C33 concrete sand screeded smoothly with 1-inch conduit pipes. Never compact the bedding sand before placing pavers.
- Concrete Pavers: Laid tight with 1/16" to 1/8" joints, secured with snap-edge plastic restraints and 10" steel spikes.
- Polymeric Joint Sand: Swept dry into the joints, compacted with the plate compactor (using a protective pad), swept again, and misted with water to activate the binding polymer.
Frequently Asked Paver Questions
Regular sand washes out during heavy rain and allows weed seeds and ant burrows to penetrate the joints. Polymeric sand contains chemical polymers that cure into an elastomeric, semi-solid joint when activated with water, preventing erosion, weeds, and insect damage while remaining flexible.
Most manufacturers package concrete pavers on pallets containing approximately 100 to 120 square feet of coverage (often 400 to 550 standard 4" × 8" bricks), weighing between 2,800 and 3,200 pounds per pallet.
Laying pavers directly on soil guarantees uneven settling, puddles, and weeds within months due to seasonal freeze-thaw cycles. Pavers can be installed over existing concrete only if the concrete is structurally sound and proper weep holes or drainage mats are installed to avoid trapping water.
