Flood Testing Labs, Inc. is a family-owned full service construction materials testing and inspection company in Chicago. Founded by Walter H Flood in 1913 in response to a desire for more structural oversight and safety in the Chicago market, Flood Testing has weathered the Great Depression, two World Wars, a family schism, and come out the other side as one of the most respected and most highly certified testing labs in the Midwest and the United States as a whole. The company was highly involved in the development of high-strength concrete in the 1960s and 70s and likes to remain on the cutting edge of construction technology and implementation. As such, FTL was among the first two labs nationally to submit itself to (and pass) the rigorous review of ISO 17025 certification through AMRL. 

Flood Testing's field technicians are highly skilled and certified and prove to be an asset on any forward-thinking project they find themselves. In recent years, FTL has focused on International Building Code work and has created a culture of ICC certification among its staff.

Flood Testing specializes in construction inspection and geotechnical design in the Chicago market, but performs consulting and specialty work worldwide. FTL principals recently consulted on and assisted with the design of the concrete mix for the reflecting pool on the National Mall. FTL also provided concrete mix design work for the South Bay Ocean Outfall, an OPAL award recipient, in San Diego.

FTL's Building Envelope Consulting division has been growing! We also specialize in roofing waterproofing and exterior walls. From forensics to moisture surveys to inspections during construction, FTL can assist with any aspect of the building envelope. We have experience in a multitude of systems throughout the US. As an independent, third-party consultant, we can ensure a proactive vs. reactive approach toward roofing, waterproofing and exterior walls.
