This rigorous independent certification under FM 2510 validates the performance of the Hammerhead® flood plank system against strict flood mitigation criteria, marking a key milestone in engineered flood defense.
POMPANO BEACH, FL, October 25, 2026 – Garrison Flood Control, a leading manufacturer of engineered flood protection systems, is proud to announce that its Hammerhead® Aluminum Flood Plank System has officially earned FM Approval under FM 2510, the Examination Standard for Flood Mitigation Equipment.
Granted on October 19th, 2026, under Approval Identification PR472193, this achievement represents a major milestone for Garrison Flood Control and its Hammerhead product line. The certification confirms that the approved Hammerhead configurations have successfully met the applicable testing and performance requirements established by FM Approvals, an independent third-party product testing and certification organization.
The approval provides property owners, engineers, architects, and facility managers with independently verified evidence of Hammerhead's ability to perform under specified flood conditions.

Tested and Certified by FM Approvals to Meet
ANSI/FM 2510 Approval Standards
“Earning FM Approval for our Hammerhead Aluminum Flood Plank System is a tremendous achievement for Garrison Flood Control.”
This certification reflects the engineering, innovation, and rigorous testing that go into developing dependable, long-lasting flood protection solutions.
For Garrison customers, it provides an added level of confidence and assurance that Hammerhead has been independently evaluated, thoroughly vetted, and proven to meet some of the industry's most demanding performance and safety standards, delivering reliable protection when it matters most.
Understanding FM 2510 and Its Importance in Flood Protection
FM 2510, also referenced in the industry as ANSI/FM 2510, establishes comprehensive testing and certification requirements for flood mitigation equipment designed to protect structures from flooding.
The standard evaluates flood protection systems through physical performance testing, engineering assessments, material examinations, and quality assurance requirements.
FM 2510 also incorporates applicable ASTM 2510 International test methods for certain material and component evaluations, including assessments involving rubber, elastomers, and other materials used in flood protection equipment.
Together, these requirements provide a standardized framework for determining whether flood mitigation products meet specific performance expectations.
For opening flood barriers like Hammerhead, the examination focuses on water resistance, structural integrity, impact resistance, deployment, and continued functionality under simulated flood conditions.
The Rigorous Testing Behind Hammerhead's FM Approval
To achieve FM Approval, flood barriers must satisfy applicable performance and examination criteria established under the FM 2510 standard. According to FM Approvals' official examination report, Garrison Flood Control's Hammerhead Flood Plank System successfully met the applicable testing and evaluation requirements of FM 2510.
Hydrostatic Pressure and Water Resistance Testing
Opening flood barriers undergo hydrostatic testing to evaluate their ability to withstand sustained water pressure without exceeding specified leakage limits.
Under FM 2510, testing at the maximum design water depth requires maintaining the water level for a minimum of 20 hours. The standard also specifies lower-water-depth testing, where applicable, to assess sealing performance under different flood conditions.
These tests help determine whether a flood barrier can maintain its protective capabilities when exposed to prolonged standing water.
Dynamic Impact Resistance Testing
Flooding frequently carries debris that can strike buildings and protective barriers.
To evaluate this risk, FM 2510 requires opening barriers to withstand at least two dynamic impacts of 600 joules each from a rigid falling object designed to simulate floating debris.
Testing examines the structural response of the barrier and its connections to the surrounding structure. Any damage resulting from the impacts must not compromise the barrier's functionality.
Deployment, Materials, and Quality Verification
FM 2510 also evaluates deployment procedures, product documentation, component specifications, and applicable material performance requirements.
This includes examining installation instructions, verifying that tested components match approved engineering specifications, and assessing the manufacturer's ability to consistently produce systems that conform to the certified design.
Strict Water Leakage Requirements
One of the most important performance requirements under FM 2510 is the allowable leakage rate.
Opening barriers must demonstrate leakage rates not exceeding 0.08 gallons per hour per linear foot of seal, evaluated over 15-minute measurement periods.
This stringent requirement assesses the effectiveness of the barrier's sealing system and its ability to limit water infiltration around and through the protected opening.
Dynamic Impact Resistance Testing
Flooding frequently carries debris that can strike buildings and protective barriers. To evaluate this risk, FM 2510 requires opening barriers to withstand at least two dynamic impacts of 600 joules each from a rigid falling object designed to simulate floating debris.
Testing examines the structural response of the barrier and its connections to the surrounding structure. Any damage resulting from the impacts must not compromise the barrier's functionality.
The Hammerhead® Aluminum Flood Plank System
The Hammerhead® Aluminum Flood Plank System is a removable flood barrier designed to protect vulnerable openings in residential, commercial, and institutional properties.
The system utilizes stackable aluminum planks that fit between vertical aluminum U-Channel posts anchored to the surrounding structure. Specialized sealing components help limit water infiltration along the planks, mounting channels, and ground surface.
A Commitment to Continued Quality and Reliability
FM Approval represents more than a one-time certification… Manufacturers of FM Approved products must maintain ongoing compliance with established quality assurance and manufacturing requirements. This includes continuing surveillance audits, production documentation controls, and verification that manufactured products remain consistent with their approved designs.
For Garrison Flood Control, the certification reinforces its commitment to developing flood protection systems that combine practical deployment with independently verified performance.
"Flood protection is about more than having a barrier in place. It's about knowing that the system has been engineered and tested to perform when it matters most," added Rosan. "While we test all of our products and conduct rigid engineering, achieving FM Approval is an important step forward for Hammerhead and reflects our continued investment in providing our customers with reliable, high-quality flood protection solutions."
With Hammerhead's newly achieved FM Approval, Garrison Flood Control continues to advance its mission of helping residential, commercial, and institutional properties strengthen their flood preparedness. For municipalities or insurance companies that require ASTM 2510 approved opening flood barrier systems, Hammerhead may now be specified for use. With the upcoming ASCE 24-24 standard, soon to replace ASCE 24-14 in state building codes, FM approval ensures Garrison remains a leader in flood protection systems, with compliant systems that meet FEMA and building code standards.
