Civil
Concrete Volume & Mix Calculator
Calculate how many cubic yards of concrete you need for a slab, footing, or pad, including a waste allowance. Use this before ordering ready-mix concrete to avoid costly shortfalls or excess.

Civil
Soil Bearing Capacity Calculator
Estimate the ultimate bearing capacity of soil beneath a square footing using Terzaghi's general bearing-capacity equation. Foundational geotechnical design input — used with appropriate safety factors to determine maximum allowable footing loads.
