Exposed Aggregate Concrete Price Per Square Metre in the United States 2026

When buyers search for exposed aggregate concrete cost per square metre, they typically pay for materials, labor, and finishing services. The price ranges reflect slab thickness, surface texture, and region-specific labor rates. This article presents realistic low, average, and high costs in USD per square metre, with per-unit details where relevant, to help budget planning and quote comparisons.

Assumptions: Midwest to Southern labor rates, standard 60–80 mm slab thickness, standard aggregate, basic sealant, normal access.

Item	Low	Average	High	Notes
Exposed aggregate finish cost per m²	$55	$70	$95	Includes surface preparation and sealant
Preparation and base concrete per m²	$25	$40	$60	Includes forming, rebar, and concrete mix
Pattern selection (coarse vs fine aggregate) per m²	$5	$10	$20	Higher for custom blends
Labor for finishing per m²	$15	$25	$40	Troweling, washing, curing
Sealing and curing per m²	$5	$8	$12	Includes two-coat sealant
Total installed cost per m²	$105	$153	$227	Assumes standard 60–80 mm thickness

Base Materials and Concrete Mix That Drive Price

The most influential cost factor is the concrete mix and the aggregate blend. Typical exposed aggregate uses a standard Portland cement mix with decorative stone, recycled glass, or natural stone chips. Material choices alone can swing per-square-metre pricing by roughly 10–40% depending on chip size, mineral content, and supply quality. Per-m² ranges account for a basic mix versus premium blends with larger chips or specialty colors.

Assumptions: Standard local cement plant supply, mid-grade decorative aggregate.

Material Component	Low	Average	High	Impact
Decorative aggregate size (mm)	6–10	10–20	20–40	Smaller chips cost less; larger chips raise price
Finish type	Salt finish, basic drag	Textured broom or light trowel	Polished look or heavy texture	Finish adds labor and time
Sealant type	Standard gloss	penetrating acrylic	penetrating epoxy	Durability and UV resistance vary

Labor and Site Factors That Affect the Quote

Labor costs vary by region, crew size, and access. Typical finishing labor runs $15–$40 per m², depending on complexity and curing requirements. If access is restricted, or the job requires formwork or elevated work platforms, labor can push the per-metre rate higher. Expectation management for busy seasons and remote sites is essential to avoid quote inflation.

Assumptions: Local crews with standard equipment; no unusual height or access constraints.

Labor Component	Low	Average	High	Notes
Finishing time per m² (hours)	0.5–0.9	1.0–1.6	2.0–3.0	Includes wash-down and light broom
Crew size	2 workers	3 workers	4 workers	Higher crew reduces time but raises labor cost
Regional wage multipliers	0.9	1.0	1.25	Urban markets higher

Region and Climate: How Geography Shifts Exposed Aggregate Pricing

Geography matters. Regions with higher labor costs or stricter permitting tend to push per-m² pricing up by 10–20% compared with cheaper markets. Coastal and metropolitan areas often require more site prep and dust suppression, influencing both materials and finishing time. Regional adjustments explain most of the spread between low and high estimates.

Assumptions: Typical urban-suburban cost delta; standard permit requirements where applicable.

Region	Low	Average	High	Notes
Northeast urban	$125	$165	$230	Higher labor and travel costs
Midwest rural	$95	$140	$190	Lower transport and crew costs
West coast	$110	$170	$240	Complex permitting in some areas

Project Scope and Thickness: What Size and Depth Do for Costs

Slab thickness and project scope strongly affect price. A standard 60–80 mm thickness yields the baseline numbers; thicker slabs or custom edge work increases material and formwork costs. If a project uses multiple slabs or spans over 100 m², bulk coordination reduces unit costs but adds mobilization complexity. Plan for a 60–80 mm range as the common reference point for residential driveways and patios.

Assumptions: Single-area application; no embedded features or drainage modifications.

Thickness	Low	Average	High	Notes
60 mm	$105	$150	$210	Most common residential spec
75 mm	$125	$170	$240	Increased material and formwork
100 mm	$150	$210	$305	Heavy-duty or vehicle load paths

Sealing, Maintenance, and Lifecycle Costs Per m²

Protection and maintenance extend the life of exposed aggregate, but add ongoing costs. Sealing per m² typically runs $5–$12 every 2–4 years, depending on sealant type and traffic. Regular cleaning and occasional resurfacing events affect long-term price. Maintenance intervals are a key total-cost driver over time.

Assumptions: Moderate traffic and standard sealant schedule.

Maintenance Item	Low	Average	High	Notes
Sealant renewal (per m², every 3 years)	$5	$8	$12	Annualized cost varies with climate
Deep cleaning (per m², every 2–3 years)	$3	$6	$9	Pressure washing eligible
Resurface or patching (per m²)	$15	$28	$50	Repairs after heavy wear

Budgeting Scenarios: Quick Quote Examples by Project Type

This section shows sample quotes to illustrate how per-m² costs translate into a full project total. Each scenario includes typical assumptions about area, thickness, and finish.

Assumptions: Patio of 40 m², 60 mm thickness, standard aggregate, mid-range sealant.

Scenario	Area (m²)	Per m² Cost	Total Installed Cost	Notes
Patio moderate finish	40	$160	$6,400	Basic broom finish with sealant
Driveway with decorative chips	60	$190	$11,400	Large chips; premium blend
Porch with smooth texture	25	$150	$3,750	Moderate labor and finish

Cost-Reduction Paths for Exposed Aggregate Projects

Smart cost control comes from scope management and efficient execution. Options include selecting standard aggregate blends, consolidating bid packages, choosing a single contractor for materials and labor, and minimizing extra features like complex borders. Careful scope control can reduce costs by 10–25% without sacrificing durability.

Assumptions: No custom inlays; standard curing regime; access is straightforward.

Strategy	Estimated Impact	Practical Step	Trade-Off
Choose mid-range aggregate	−$10 to −$25 per m²	Review material catalogs with supplier	Less unique look
Bundle materials and labor	−$15 to −$40 per m²	Contract a single firm for project scope	Less negotiation flexibility
Limit edge work and finishes	−$5 to −$15 per m²	Avoid decorative borders	Simpler aesthetic

Key Variables That Most Change the Final Quote

Two strong drivers are aggregate chip size and project area. Larger chips with specialty colors raise material costs, while expanding area increases both materials and labor. A second major driver is access and site conditions; restricted access can add handling time and equipment rental. Numeric thresholds: chip size over 20 mm and area above 100 m² commonly push quotes to the high end.

Assumptions: Standard driveway or patio with typical access.

Variable	Typical Range	Cost Sensitivity	Notes
Chip size (mm)	6–40	High for 20–40	Larger chips require more material handling
Project area (m²)	20–120	Directly scales	Bulk pricing often marginally better per m² at larger scales
Site access	Excellent to restricted	Moderate to high	Equipment rental and scheduling impact

Frequently Used Assumptions and Measurement Notes

All prices are in USD and reflect installed work in residential settings in the United States, assuming standard weathering exposure and a typical 60–80 mm thickness. Slab color, finish texture, and edge detailing are priced separately. Per-m² quotes must be compared with similar scope and finish levels for accuracy.

Assumptions: No structural reinforcement beyond standard forms; standard curing period observed.
