FM-certified flood doors make flood protection more than just “blocking water”—they achieve millimeter-level precision control.
During heavy rain, the entrances and exits of underground garages are often the first points where floodwaters break through.
But at the bioMérieux (Suzhou) Biotech Co., Ltd. campus, a single FM-certified flood door redefined what “flood protection” means with one field test.
According to the FM 2510 international standard, the project team built a temporary cofferdam on-site, filled water to a level of 400 mm, and monitored leakage for 120 minutes.
The final result: just 126 milliliters—roughly the volume of a small cup of coffee.
By the standard, the allowable maximum leakage should be 6.32 liters, making the actual result only 1/50 of the standard.
This means that even with two hours of continuous flooding, the area behind the door remains virtually “dry.”
On the day of acceptance, the client expressed high satisfaction: “This door truly gives peace of mind.”
From the data to the site, this “cup-of-coffee” difference reflects not coincidence, but the ultimate pursuit of sealing, craftsmanship, and standard compliance.
True flood protection is not about emergency repair after the disaster—it’s about guarding every millimeter beforehand.
Conclusion:
When flood protection precision is quantified as “the volume of a cup of coffee,” it means risk control has evolved from an engineering concept into a verifiable, auditable resilience capability.
This is the real value behind FM certification.
