Terms of Service & Estimation Disclaimer

Effective Date: September 19, 2026 Domain: Gravelcalculatorpro.com Inquiries: gravelcalculatorpro@gmail.com

CRITICAL CONTRACTOR & HOMEOWNER NOTICE: All figures, volumes (cubic yards, cubic feet, cubic meters), tonnage weights (US tons, metric tonnes), and bag counts generated on GravelCalculatorPro.com are mathematical approximations designed for preliminary budgeting and reference only. Because material moisture, stone compaction, quarry density, and subgrade grading differ between geographical locations and vendors, you must confirm final order specifications with your local bulk aggregate supplier prior to ordering.

1. Acceptance of Agreement

By accessing, browsing, or using the calculators, data charts, and guides on GravelCalculatorPro.com (referred to as “the Site”, “we”, “us”, or “our”), you acknowledge that you have read, understood, and agree to be legally bound by these Terms of Service. If you do not agree to these terms, please discontinue use of this site immediately.

2. Permitted Use & Intellectual Property

GravelCalculatorPro.com provides free access to interactive mathematical tools, aggregate density charts, and depth guidelines. Users are granted a personal, non-exclusive, revocable license to utilize the calculator for personal projects, landscape planning, and commercial contractor estimating.

You may not scrape, frame, harvest via automated bots, re-host, reverse-engineer, or redistribute the proprietary calculation algorithms, table databases, or written guides without explicit prior written authorization from GravelCalculatorPro.com.

3. Physical Variance Factors & Disclaimers

Calculations performed on this website use standardized civil engineering formulas (such as $Volume = Area \times Depth$ and $Weight = Volume \times Density$). While these formulas provide exceptional baseline estimates, actual job site requirements invariably fluctuate due to:

Moisture Weight: Uncovered aggregate piles absorb rainwater. Wet gravel or crushed stone can weigh between 5% and 15% more than dry stone, affecting scale ticket tonnage without altering delivered volume.
Geological Origin: Specific gravities vary by rock type (granite, limestone, basalt, quartzite, dolomite, river pebble). A cubic yard of crushed limestone typically weighs between 2,700 and 2,900 lbs, whereas basalt can exceed 3,100 lbs per cubic yard.
Compaction & Particle Distribution: Crusher run / road base aggregates (which mix fine stone dust with angular rocks) compact by 10% to 20% when rolled or vibrated with mechanical plate compactors.
Subgrade Irregularities: Natural soil foundations and excavated ground are rarely laser-flat; rutting, slopes, and soft subgrade consume additional stone.

We strongly advise ordering a 5% to 15% waste/compaction buffer and verifying scale weights with your quarry master or bulk aggregate dispatcher.

4. Limitation of Liability

Under no circumstances shall GravelCalculatorPro.com, its owners, operators, developers, or affiliates be held liable for any direct, indirect, incidental, consequential, special, or exemplary damages, including but not limited to:

Shortages of materials requiring secondary delivery fees or demurrage fees
Excess aggregate purchase costs or restocking surcharges
Structural instability, driveway subsidence, or foundation failure resulting from inadequate depth or compaction
Project delays, labor disputes, or equipment rental fees

You assume complete responsibility for confirming your material quantities with certified professional suppliers before submitting purchase orders.

5. Advertising & Third-Party Services (Google AdSense)

GravelCalculatorPro.com displays commercial advertisements served by third-party advertising networks, including Google AdSense. We do not endorse, guarantee, or assume liability for the products, pricing, delivery schedules, or services promoted by third-party advertisers.

You agree to defend, indemnify, and hold harmless GravelCalculatorPro.com and its operators from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable legal fees) arising from your violation of these Terms of Service or your reliance on calculations provided on this site.

7. Governing Law & Jurisdiction

These Terms shall be construed and governed in accordance with applicable laws without regard to conflict of law principles. Any dispute arising under or in connection with these terms shall be subject to the exclusive jurisdiction of the competent courts.
