Clear statutory disclosures regarding our calculation models, engineering tolerances, and the vital role of on-site licensed Professional Engineers (P.E.).
The calculation tools, diagnostic engines, and written guides provided on FoundationRepairUS.com are strictly intended for preliminary homeowner education, rough budgeting, and contractor bid verification. They do not constitute formal structural engineering advice, design blueprints, or official certifications. No online tool can replace an on-site physical evaluation conducted by a qualified, licensed Professional Engineer (P.E.).
State laws strictly regulate the practice of professional engineering. In every U.S. state and Canadian province, providing stamped structural calculations, signing repair blueprints, or issuing legal certificates of structural adequacy requires an active Professional Engineer (P.E.) or Structural Engineer (S.E.) license issued by the state licensing board.
FoundationRepairUS is an independent informational and technology platform. Accessing this Website or utilizing its interactive calculation engines does not establish an engineer-client, architect-client, or contractual relationship between you and FoundationRepairUS or any contributing engineer.
Our calculation models utilize prescriptive engineering formulas from recognized building codes, including IBC Chapter 18, IRC Chapter 4, ACI 318, and ICC-ES AC358. However, all digital models rely on standardized assumptions that may not reflect your home's unique conditions:
You must engage a local licensed Professional Engineer (P.E.) to conduct an on-site evaluation in any of the following circumstances:
Basement walls bowing inward more than two inches or shearing horizontally at the base block require immediate engineered shoring.
Differential foundation settlement exceeding 1.5 inches over a 30-foot span indicates active soil failure requiring geotechnical borings.
Most city building departments require sealed P.E. drawings before issuing permits for structural underpinning or egress window wall cutouts.
Mortgage underwriters and relocation companies require an official blue-sealed engineering letter to approve loan financing on homes with structural distress.
If you detect the odor of natural gas, hear sudden cracking sounds within timber or masonry framing, observe rapid door and window frame binding within hours, or notice a rapid collapse of earth surrounding your foundation, evacuate the structure immediately and dial 911. Do not consult online calculators during an active structural collapse or gas leak event.
