Prices for Exposed Aggregate and Stamped Concrete depend on surface texture, concrete mix, edge work, and site conditions. This guide presents cost ranges in USD, with clear low–average–high estimates and per-unit specifics where relevant. The main cost drivers include material type, labor time, pattern complexity, and preparation requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Project scope | $3,000 | $8,000 | $15,000 | Patio, walkway, or driveway |
| Per-square-foot | $6 | $10 | $18 | Average ranges vary by texture |
| Pattern complexity | $0 | $2,000 | $6,000 | Stamp patterns add cost |
| Edge work | $300 | $1,000 | $3,000 | Curves or decorative borders |
| Prep & demolition | $500 | $2,500 | $5,000 | Existing slabs or repairs |
Overview Of Costs
Cost ranges reflect typical residential applications in the United States. For Exposed Aggregate and Stamped Concrete, the overall price difference hinges on aggregate size, release agents, stamp set wear, and sealing needs. Assumptions: region, slab size, maintenance interval.
Cost Breakdown
The following table summarizes a standard project, including both total project ranges and per-unit figures where applicable. The values assume a typical 500–1,500 square foot area and common preparation steps such as cleaning, leveling, and backfill.
| Category | Materials | Labor | Equipment | Permits | Contingency | Taxes |
|---|---|---|---|---|---|---|
| Exposed Aggregate | $2,400–$5,500 | $2,800–$5,000 | $500–$1,200 | $0–$600 | 10–15% | 0–8% |
| Stamped Concrete | $3,000–$6,800 | $3,000–$6,200 | $600–$1,250 | $0–$700 | 12–18% | 0–8% |

What Drives Price
Texture and pattern complexity heavily impact cost. Exposed aggregate uses embedded stones and a release agent; stamping requires interlocking mold patterns and multiple color pours. Site preparation (grading, drainage, and crack repair) can add 5–20% to the base price. Sealing and maintenance add ongoing costs of about $0.50–$1.50 per sq ft every 2–3 years.
Regional Price Differences
Prices can vary by region due to labor markets and material availability. In urban West Coast areas, expect higher labor rates; in rural Southeast regions, material transport and subcontractor availability influence totals differently. Typical delta ranges by region: West Coast +10–25%, Midwest +5–15%, Southeast -5–10% relative to national averages.
Labor, Hours & Rates
Labor costs accrue from surface preparation, formwork, stamping or aggregate embedding, and curing. A 1,000 sq ft patio may require 40–90 hours of crew time depending on texture and pattern. Hourly rates commonly range from $50 to $100 per hour for skilled masons and finishers.
Additional & Hidden Costs
Hidden costs can include extended curing time for heavy aggregates, edge restoration, and drainage adjustments. Sealers, color hardeners, and release agents add to material expenses, typically $0.60–$2.00 per sq ft. Demolition or disposal of old surfaces can incur $200–$1,200.
Real-World Pricing Examples
Scenario cards illustrate typical job configurations and costs.
Basic: Small Patio with Simple Stamp Pattern
Specs: 400 sq ft, simple 1-color stamp, standard edge. Labor: 24–40 hours. Per-unit: $8–$12/sq ft. Total: $3,200–$4,800. Notes: Minimal site prep, standard sealer at completion.
Assumptions: suburban site, no complex drainage, basic stamp set.
Mid-Range: Larger Patio with Exposed Aggregate Border
Specs: 900 sq ft, exposed aggregate main surface with decorative border, medium complexity. Labor: 40–70 hours. Per-unit: $9–$14/sq ft. Total: $8,100–$12,600. Notes: Involves stone mix, release agent, and two-step sealing.
Assumptions: moderate site prep, standard aggregate color.
Premium: Driveway with Custom Stamp Pattern and Sealed Finish
Specs: 1,200 sq ft, multiple stamps, color integration, edge work, enhanced sealer. Labor: 70–110 hours. Per-unit: $12–$18/sq ft. Total: $14,400–$21,600. Notes: Higher material variety, longer curing window, premium sealer.
Assumptions: larger project, complex layout, good drainage.
Maintenance & Ownership Costs
Final costs should include resealing every 2–3 years to maintain surface integrity, typically $0.50–$1.50 per sq ft per reseal. For aggregate surfaces, occasional stone exposure may require re-etching or re-polishing. Five-year cost outlook often adds 5–15% of initial price for maintenance and minor repairs.
