What Flood Testing Laboratories does

Flood Testing Laboratories Inc. is a Chicago-based, family-owned construction materials testing and inspection firm founded in 1913 by Walter H. Flood and currently operating under fourth-generation family ownership. The company provides professional testing and inspection services across five core service lines: Buildings Testing (structural steel, concrete, masonry, fireproofing, post-tensioning, post-installed anchors under ICC Special Inspector frameworks), Infrastructure Testing (IDOT/CDOT certified QA/QC for roadways, bridges, airports, and transit), accredited Laboratory Testing (AASHTO R18 and ISO 17025 accredited materials testing), Geotechnical Investigation (deep borings, pressure meter testing, soil classification, CBR tests), and Roofing/Waterproofing inspection using non-destructive infrared and radioisotopic moisture surveys. Technical capabilities include AWS Certified Welding Inspectors performing UT, PT, and MT inspections and expertise in high Modulus of Elasticity concrete testing up to 8 million psi.

The firm generates revenue through project-based professional services fees billed to contractors, engineers, building owners, and public agencies, with a sales-led B2B go-to-market focused on the Midwest region. Notable client engagements include the Illinois Quantum Microelectronics Park (IQMP), O'Hare International Airport Terminal 5 Expansion, CTA Red Purple Line Modernization, and the St. Regis Chicago tower. The company supports clients through a secure Omnant-platform client portal with multi-factor authentication for accessing test results and project documentation. Headcount is reported at 11-50 employees.

Flood Testing Laboratories is privately held with no external funding, parent company, or public listing, and is led by President Susanne M. Hufnagel, who has held the role since 1995. Marketing is limited to a corporate website, Google Places listing, LinkedIn page, and Facebook page. The firm holds ISO 17025 and AASHTO R18 laboratory accreditations, complies with ASTM E329, and is regularly inspected by AMRL, CCRL, and the Illinois Department of Transportation, which collectively serve as gating credentials for public infrastructure work. No AI, software-as-a-service, or recurring subscription revenue components are present in the business model.
