Terms of Service

1. Acceptance of Terms

By accessing, browsing, or utilizing Gravel Calculator ("the Site," "we," "us," or "Gravel-Calc.com"), including any of our specialized estimation tools (such as Driveway, Cost, Square Footage, Concrete Slab, French Drain, Trench, Paver, Circular, Gravel Grid, and Aquarium calculators), you acknowledge that you have read, understood, and agree to be bound by these Terms of Service. If you do not agree with any part of these terms, you must discontinue use of the Site immediately.

2. Purpose & Permitted Use

Gravel Calculator provides free, web-based mathematical estimation utilities designed to assist homeowners, landscape designers, civil contractors, DIY builders, and aquarists in estimating aggregate volumes (cubic yards, cubic feet), weight tonnage, 50 lb bag requirements, compaction allowances, and project material budgets.

You are granted a non-exclusive, non-transferable, revocable license to access and use our tools solely for lawful personal, educational, or professional project planning purposes.

3. Mathematical Calculation Disclaimer & Material Variances

All figures, calculations, output quantities, and cost breakdowns generated by Gravel-Calc.com are mathematical estimates provided for informational planning purposes only.

• Density & Aggregate Variances: Standard material densities (e.g. 2,700 kg/m³ for pea gravel, 2,500 kg/m³ for crushed stone) are averages. Actual rock density varies significantly based on quarry origin, moisture content, geology, and particle sizing.
• Excavation & Compaction Loss: Field excavation depths are rarely perfectly uniform. Compaction rates vary based on soil subgrade stability, mechanical plate compaction force, and moisture levels during installation.
• Supplier Verification Required: Users are strongly advised to verify final material calculations with a licensed civil contractor, landscape engineer, or local quarry supplier before placing non-refundable bulk gravel orders.

4. Prohibited Uses & Platform Integrity

When using Gravel Calculator, you agree that you will not:

• Use automated scrapers, bots, spiders, or data extraction scripts to harvest calculator outputs, code, or site assets without explicit written authorization.
• Attempt to bypass site security, overload our infrastructure through denial-of-service (DoS) attacks, or inject malicious code into contact forms.
• Frame, mirror, or re-brand Gravel-Calc.com tools on external domains without attribution and prior written consent.
