About Yard & Slab
Yard & Slab (yardandslab.com) was founded by US building contractors, civil engineers, and software architects with a singular mission: to eliminate guesswork and material waste on American jobsites.
Our Core Mission
While corporate retail calculators force homeowners and contractors through blank input forms that ignore real-world physics, Yard & Slab provides instant, pre-solved calculations that account for actual timber dimensions, pipe displacement, US climate zones, and retail packaging SKUs.
Why Yard & Slab Is Different
Real Physical Dimensions
We account for nominal vs. actual timber sizes (e.g. 3.5" for 4x4 posts) and corrugated pipe displacement in French drains, preventing costly material over-ordering.
Standard US Store SKUs
Outputs correspond directly to 40lb, 60lb, and 80lb Quikrete bags, #57 stone tons, 5-gallon mud buckets, and 20-ft rebar sticks found at Home Depot and Lowe's.
Zero-Click Pre-Solved URLs
Over 160+ programmatic landing pages give you the exact bag and material count instantly in the headline, with interactive sliders to tweak as needed.
Code & Standard Compliance
Formulas strictly follow the International Residential Code (IRC), American Concrete Institute (ACI 318), ASTM International standards, and IECC Climate Zones.
Editorial & Review Process
Every calculator and contextual guide published on Yard & Slab undergoes rigorous mathematical validation by experienced trade professionals. For more details on the exact engineering standards and peer review methods we employ, please inspect our Editorial Policy & Engineering Standards.
