Many flood barrier companies take pride in having FM approval for flood barriers they provide. But what is it, and should you actually ask for it from your flood barrier installer? Let’s break it down.
What Is FM Approval?
FM Approval is a certification from a private, independent company called FM Global. It tests products to see if they meet certain safety and performance standards. For flood barriers, FM looks at things like:
- Structural Integrity – Can it handle water pressure without bending or breaking?
- Water Tightness – Does it actually stop water from passing through?
- Impact Resistance – Can it resist floating debris during a flood?
- Installation Guidelines – Does the product work as intended when installed correctly?
- Maintenance Requirements – Are there clear instructions to keep it functioning?
- Testing Standards – Has it passed certified lab tests?
Is FM Approval Necessary?
No, it’s not required. FM approval is voluntary. Many high-quality flood barriers on the market don’t have it, and that doesn’t make them unsafe.
Is FM Approval for Aluminum Plank Barriers FEMA Certified?
No. FM approval is not FEMA certification.
FM approval comes from a private company and tests products against their own safety and performance standards. FEMA, on the other hand, sets government flood safety guidelines. A product can be FM-approved but not necessarily meet FEMA requirements, and vice versa.
For flood barriers, FEMA compliance and proper load calculations are far more important for real-world protection than FM approval alone.
Are Products Without FM Approval Unreliable?
Not necessarily. Many products perform just as well or better than FM-approved barriers. What matters most is the product’s actual specifications and engineering, not a sticker on the box.
If a Company Doesn’t Have FM Approval, Should You Avoid Them?
Not at all. Lack of FM approval doesn’t automatically mean the barrier is bad. What’s more important is:
- Compliance with FEMA regulations – Make sure the barrier meets local flood safety guidelines.
- Load Calculations – Ask the company for their load calculation. This shows exactly how much water pressure the barrier can handle safely.
- Product Specifications – Look for aluminum thickness, panel height, and structural design that can withstand flood forces.
Why Load Calculation Matters More Than FM Approval
Load calculation is a technical measurement of how much force a flood barrier can take before it fails. It’s based on real-world scenarios like water height, velocity, and debris impact. Even an FM-approved barrier could fail if it’s not strong enough for your specific situation. A solid load calculation from the manufacturer or engineer gives you real confidence.
Minimum Specs to Look For in Aluminum Flood Barriers
When evaluating non-FM approved barriers, here are some baseline specs:
- Panel Material – High-quality aluminum, typically at least 0.078–0.125 inches thick
- Height – Enough to cover your expected flood level plus a safety margin
- Support System – Strong braces, anchors, or tracks to handle water pressure
- Seal Quality – Gaskets or seals that prevent leaks
- Durability – Resistant to corrosion, bending, and repeated use

So, Do You Need FM Approval?
No, you don’t. FM approval is not a guarantee of better performance. The most important factors are real-world engineering, product specifications, and proof the barrier can handle the water load it might face.
When choosing a flood barrier:
- Check that it meets FEMA regulations.
- Ask the company for their load calculation.
- Make sure the product specs are strong enough for your property.
FM approval can be nice to have, but it’s more about marketing than necessity. Your priority should be a well-engineered, tested, and properly installed barrier that actually works when the water comes.
