1. Practical Gravel & Weight Estimation Disclaimer
While our semi-circle and rectangular volume formulas are mathematically exact, real-world gravel requirements can vary by 5% to 10% due to corrugated steel wall ribs, stone moisture content at the quarry, and natural settling. We always recommend rounding up to the next full 50-lb bag.
2. Basement Egress & Building Code Compliance (IRC R310)
Emergency basement escape windows are regulated by local municipal building codes (such as IRC Section R310). Never pour gravel to a height that blocks the outward swing of a basement window or reduces required emergency egress ladder clearance.
3. Limitation of Liability
WindowWellGravel.online provides DIY estimation tools and informational guides "as is" without warranty. We are not liable for basement water seepage, foundation leaks, or over/under-ordered landscaping materials. For active basement flooding, consult a licensed waterproofing contractor.
