Frequently Asked Questions

Q

How do I calculate how many pavers I need?

Divide your project area (sq ft) by the paver size (sq ft). For 4×8" pavers (0.22 sq ft each): 200 sq ft ÷ 0.22 = 909 pavers. Add 5-10% for cuts and waste, especially for diagonal patterns.

  • Standard 4×8" brick pavers: 4.5 pavers per sq ft; 6×6" pavers: 4 per sq ft; 12×12" pavers: 1 per sq ft
  • Running bond pattern wastes 5%; herringbone 45° wastes 10%; circular patterns waste up to 15%
  • Order by the pallet — typical pallet holds 400–540 pavers (4×8") or 120 (12×12") and costs $250–$600
  • Measure your area in feet and convert paver dimensions to feet: 4" = 0.333 ft, 8" = 0.667 ft
  • Keep 20–30 extra pavers stored for future repairs — matching discontinued colors years later is extremely difficult
Q

How much sand do I need under pavers?

You need 1 inch of bedding sand under pavers. For 100 sq ft, that's about 0.31 cubic yards or 500 lbs of sand. Also add polymeric sand for joints: about 50 lbs per 100 sq ft.

  • Bedding sand: 1" layer of coarse concrete sand (ASTM C33); never use mason or play sand
  • A 200 sq ft patio needs ~0.62 cubic yards of bedding sand (roughly 1,000 lbs or half a ton)
  • Polymeric sand fills joints and hardens when wet — budget 50 lbs per 100 sq ft of paver surface
  • A 50 lb bag of polymeric sand costs $20–30 and covers approximately 50–75 sq ft of standard pavers
  • Screed the bedding sand with 1" PVC pipes as rails for a perfectly level surface before laying pavers
Q

How deep should the gravel base be for pavers?

Paver base depth depends on use: Patios need 4" gravel base. Driveways need 6-8" for vehicle weight. Add 1" sand leveling layer on top. Total excavation: 6-10 inches plus paver thickness.

  • Walkways: 4" compacted gravel base is sufficient for pedestrian traffic only
  • Patios: 4–6" gravel base; add geotextile fabric underneath to prevent soil migration
  • Driveways: 6–8" gravel base for cars; 8–12" for heavy vehicles like RVs or trucks
  • Compact gravel in 2" lifts with a plate compactor — each lift compresses ~20% and must be wetted
  • Total excavation depth = gravel base + 1" sand + paver thickness (2.375" standard) = 7.4–11.4"

Heavy vehicles8–12"1"11.5–15.5"
Q

How much do pavers cost installed?

DIY paver cost: $3-6 per sq ft for materials (pavers, sand, gravel). Professional installation: $10-25 per sq ft total. Concrete pavers cost less than natural stone or permeable pavers.

  • Concrete pavers: $0.50–$2.50 per paver; natural stone: $3–$10 per paver
  • Base materials (gravel + sand) add $1–$2 per sq ft regardless of paver type
  • Professional labor runs $6–15 per sq ft depending on pattern complexity and local rates
  • A 200 sq ft DIY patio costs roughly $600–$1,200 in materials; professionally installed: $2,000–$5,000
  • Permeable pavers cost 20–30% more but may qualify for stormwater management rebates in some municipalities
Paver TypeMaterial Cost/sq ftInstalled Cost/sq ftLifespan

Permeable$4–$8$12–$2225–40 years
Porcelain$5–$12$15–$3030–50 years
Q

What paver pattern is best for driveways?

Herringbone (45° or 90°) is strongest for driveways due to interlocking. Running bond is easiest for DIY. Basketweave adds visual interest. Avoid stacked bond for driveways as it can shift under load.

  • Herringbone 45° is the strongest pattern — used in airport runways and commercial parking lots
  • Running bond is the easiest DIY pattern with only 5% waste and simple straight cuts
  • Herringbone 90° is slightly easier to lay than 45° but equally strong for driveways
  • Basketweave and stacked bond patterns are decorative but not recommended for vehicular traffic
  • Border pavers in a contrasting color or orientation add a professional finished look for $1–2/linear ft extra

Calculating Pavers, Sand, and Gravel by Project Size

A 200 sq ft patio using standard 4×8-inch brick pavers at 4.5 pavers per square foot requires roughly 900 pavers before waste — plus 5–10% extra depending on the laying pattern. Running bond adds 5% for cuts, while herringbone at 45° adds 10% because diagonal cuts at the border waste more material. For a 200 sq ft herringbone patio, budget 990 pavers (900 × 1.10).

Bedding sand runs 1 inch deep under the pavers: 200 sq ft at 1 inch of depth equals 0.62 cubic yards or approximately 1,000 lbs of coarse concrete sand (ASTM C33). Polymeric sand fills the joints at roughly 50 lbs per 100 sq ft, costing $20–$30 per 50-lb bag. For 200 sq ft, plan on two bags totaling $40–$60.

Gravel base depth depends on the application. Patios need 4 inches of compacted gravel, while driveways require 6–8 inches to support vehicle weight. A 200 sq ft patio with a 4-inch base uses approximately 2.5 cubic yards of crushed gravel at $40–$50 per yard. The concrete calculator can help estimate alternative slab foundations if pavers are not the right fit.

Paver Patterns and Their Waste Factors

Running bond is the simplest pattern with only 5% waste from straight border cuts, making it the go-to choice for DIY installers. Pavers are offset by half their length in alternating rows, creating a staggered brick look. A 200 sq ft patio in running bond wastes just 10 sq ft of material.

Herringbone at 45° is the strongest pattern — interlocking pavers resist lateral shifting under vehicle loads, which is why it appears on airport runways and commercial parking lots. The tradeoff is 10% waste from diagonal border cuts, adding $50–$100 in extra paver cost for a typical driveway. Herringbone at 90° is slightly easier to install with 8% waste but equally strong.

Basketweave and stacked bond patterns create attractive geometric designs for patios and garden paths. However, their parallel joint lines make them unsuitable for vehicular traffic because loads can push pavers sideways along the continuous seam. Border rows in a contrasting color add a professional finished edge for $1–$2 per linear foot of additional material.

Tip: Always order 20–30 extra pavers beyond the waste factor and store them for future repairs. Matching discontinued paver colors years later is extremely difficult.

Building the Right Base: Gravel Depth by Application

The gravel base is the most critical part of paver installation — 90% of paver failures (sinking, shifting, heaving) trace back to an inadequate base. Compact gravel in 2-inch lifts with a plate compactor, wetting each lift before compacting. Each layer compresses roughly 20%, so you need to start with 20% more loose gravel than the finished depth.

Geotextile landscape fabric between the soil and gravel prevents fine particles from migrating into the base and weakening it. A 200 sq ft project needs about 250 sq ft of fabric (accounting for overlap) at $0.15–$0.25 per square foot. This $40–$60 investment prevents thousands of dollars in rework.

Total excavation depth equals gravel base + 1 inch of sand + paver thickness (2.375 inches for standard brick pavers). A patio digs to 7.4 inches, while a driveway digs to 11.4 inches. Rent a mini-excavator ($200–$300/day) for projects over 300 sq ft — hand-digging 400 sq ft to 10 inches removes roughly 12 cubic yards of soil.

Material Costs: DIY vs. Professional Installation

DIY paver installation costs $3–$6 per square foot for materials alone. For a 200 sq ft patio using concrete brick pavers, expect $600–$1,200 total: $450–$800 for pavers, $50–$80 for sand, and $100–$200 for gravel. Add $50–$100 for edge restraints, polymeric sand, and landscape fabric. The gravel calculator helps dial in the exact base material quantity.

Professional installation runs $10–$25 per square foot including labor and materials. That same 200 sq ft patio costs $2,000–$5,000 installed by a contractor. Labor accounts for 60–70% of the professional price. Complex patterns (herringbone, circular) and multi-level designs push toward the higher end.

Natural stone pavers cost 2–3× more than concrete but last 50–100 years versus 25–50 for concrete. Permeable pavers cost 20–30% more than standard concrete but may qualify for municipal stormwater rebates that offset the premium.

  • Concrete brick pavers — $0.50–$2.50 each; 25–50 year lifespan with minimal maintenance
  • Natural stone (bluestone, travertine) — $3–$10 each; 50–100 year lifespan, unique appearance
  • Permeable pavers — $4–$8 per unit; reduce runoff by 80–90%, may earn stormwater credits
  • Porcelain pavers — $5–$12 each; stain-resistant, frost-proof, modern aesthetic
  • Plate compactor rental — $80–$120/day; essential for proper base and final paver seating

Step-by-Step Paver Installation Process

A well-executed paver project follows the same sequence whether it is a 50 sq ft walkway or a 500 sq ft driveway. Skipping or shortcutting any step — especially excavation and compaction — leads to settling, gaps, and weed growth within 1–2 seasons.

Budget 2–3 full days for a 200 sq ft DIY patio: day one for excavation and base gravel, day two for sand and paver laying, and a half day for cutting, jointing, and final compaction. The deck calculator can help compare whether a paver patio or wooden deck better fits your budget and timeline.

  1. 1

    Excavate to depth

    Dig 7.5–11.5 inches below finished grade depending on application. Slope 1/4 inch per foot away from structures for drainage.

  2. 2

    Install landscape fabric and gravel

    Lay geotextile fabric, then spread crushed gravel in 2-inch lifts. Compact each lift with a plate compactor until no movement is visible.

  3. 3

    Screed bedding sand

    Spread 1 inch of coarse concrete sand (ASTM C33). Use two 1-inch PVC pipes as screed rails for a perfectly level surface.

  4. 4

    Lay pavers and cut borders

    Start from a straight edge or corner. Maintain consistent 1/8-inch joint spacing. Use a wet saw for clean border cuts.

  5. 5

    Compact and joint

    Run the plate compactor over the pavers to seat them into the sand. Sweep polymeric sand into joints, mist with water to activate the binding agent.
