How foundation math works in seconds: Enter wall loads with soil capacities to get footing widths plus depths together. Results appear at $0 cost in your browser.
Why bearing matters for USA additions on 09/22/2026: Undersized footings settle differentially and crack everything above slowly. Austin additions bearing $150,000 second stories verify soils first. Seattle ADUs perching $250,000 hillside posts engineer for slopes.
Wind exposures: Miami fences anchoring $40,000 hurricane exposures size for overturning forces, not just weight. Denver decks carrying $60,000 snow loads oversize for drift zones.
Parapet rebuilds: New York parapets rebuilding $500,000 roof edges match historic profiles exactly. Chicago garages sitting $90,000 slab thickenings pour monolithically.
Test-pit law: Dig test pits before designing — clays surprise even veteran builders regularly.
Neighbor excavations: Boston brownstones underpinning $9M adjacent digs monitor movement daily. Chicago high-rises monitoring $90M settlement arrays read prisms on 09/22/2026.
Pile caps: Miami towers founding $90M deep-pile caps test integrity sonically. Phoenix data centers founding $90M slab placements proof-roll subgrades.
Classroom wings: Denver schools expanding $20,000 modular wings found pier pads. Frost probes confirm bearing depths.

Frequently Asked Questions
- How do you calculate what percent one number is of another in foundation?
- Divide the part value by the total value and multiply by 100. For example, to find what percent 75 is of 200, calculate 75 divided by 200 times 100 which equals 37.5 percent. This formula works for any two numbers and is the foundation of all foundation percentage calculations. The Foundation Calculator v2 handles this instantly.
- How do I find the original number when I know the percentage for foundation?
- Divide the percentage value by the percentage rate expressed as a decimal. For example, if 45 is 30 percent of a number, divide 45 by 0.30 to get 150. This reverse calculation is useful for determining original prices before discounts, finding total foundation amounts from partial information, and working backward from known percentages.
- What are the most common uses for percentage calculations in foundation?
- Percentages are used for calculating grades, computing discounts and markups, determining tax amounts, analyzing statistics, calculating interest rates, measuring growth or decline, comparing proportions in surveys, and many everyday financial and academic tasks. The Foundation Calculator v2 simplifies all of these foundation percentage scenarios.
- Can a percentage in foundation be greater than 100?
- Yes, percentages can exceed 100. For example, if a company doubles its revenue from $500,000 to $1,000,000, that represents a 100 percent increase. Values greater than 100 percent indicate that the part exceeds the whole, which commonly appears in growth measurements and comparative analyses within foundation contexts.
- How do I calculate the percentage increase or decrease for foundation?
- Subtract the original value from the new value, divide by the original value, and multiply by 100. A positive result is an increase, while a negative result is a decrease. For example, a price increase from $80 to $100 represents a 25 percent increase. The Foundation Calculator v2 handles all foundation percentage change calculations automatically.
