Exposed Aggregate Concrete Cost Formula:
| From: | To: |
Exposed aggregate concrete is a decorative concrete finish where the top layer of cement paste is removed to reveal the underlying aggregate (stones, pebbles, or shells). This creates a textured, slip-resistant surface that is both functional and aesthetically pleasing.
The calculator uses the following formula:
Where:
Explanation: The calculation multiplies the total area by the cost per square foot to determine the total project cost. The $8-12/ft² range accounts for variations in material quality, labor costs, and project complexity.
Details: Accurate cost estimation is crucial for budgeting concrete projects, comparing contractor quotes, and ensuring financial feasibility. Exposed aggregate typically costs more than standard concrete but offers superior durability and aesthetic appeal.
Tips: Enter the total area in square feet and select a cost per square foot between $8 and $12. The calculator will provide both the specific cost and the overall cost range for your project.
Q1: Why does exposed aggregate cost more than regular concrete?
A: The additional cost comes from specialized materials, extra labor for surface preparation and washing, and the skill required to achieve consistent exposure of the aggregate.
Q2: What factors affect the cost per square foot?
Q3: How durable is exposed aggregate concrete?
A: Very durable. The exposed aggregate surface is highly resistant to wear, weathering, and slipping, making it ideal for driveways, patios, and pool decks.
Q4: Can I install exposed aggregate myself?
A: While possible for small DIY projects, professional installation is recommended for best results due to the specialized techniques required for proper aggregate exposure and finishing.
Q5: How do I maintain exposed aggregate concrete?
A: Regular cleaning with mild detergent and periodic sealing (every 2-3 years) will maintain its appearance and protect against stains and weathering.
