Operating temperature range: Approximately −10°F to 115°F

Connection system:

• Lower insert-and-lock connection
• Upper spring-loaded locking mechanism
• Tool-free normal assembly and dismantling

Ground sealing:

• Neoprene foam seal along the front underside
• Extended flexible PVC ground flap
• Heavy-duty hook-and-loop connections between adjacent flaps

Configuration options:

• Straight panels
• Inward curved sections
• Outward curved sections
• Gentle directional adjustment between straight panels
• Full-perimeter configurations
• Left and right gable ends
• Optional rear support brackets

Turning capability:

• Straight connections allow approximately three degrees of adjustment in either direction
• Three compatible curved sections can create an approximately 90-degree turn

Approximate deployment rate: Up to three sections per minute under suitable conditions with prepared personnel

Approximate deployment example: Roughly 15 minutes for 100 feet under suitable conditions

Storage: Panels stack for compact storage

Maintenance: Wash after use and allow all components to dry before stacking

Mayim MAX components use different connections and sealing features from standard 20-inch and 30-inch Mayim panels and should not be assumed to be interchangeable.

Plan the Mayim MAX layout and identify all straight sections, turns and wall terminations before a flood event. Practice deployment with the personnel responsible for installation.

Deployment steps:

1. Inspect the installation route and remove sharp objects, large debris and other obstructions.
2. Transport the stacked panels to the deployment area by hand, dolly, pallet or suitable material-handling equipment.
3. Begin connecting panels from the left side of the planned barrier run.
4. Position each panel with its L-shaped base facing toward the expected floodwater.
5. Tip the next panel slightly and insert its lower connector prong into the receiver loop of the adjoining panel.
6. Lower the panel into position and engage the upper spring-loaded locking mechanism.
7. Continue connecting panels along the planned route.
8. For uneven surfaces, release the yellow PVC ground flaps and lay them flat toward the expected water.
9. Connect adjacent ground flaps using their heavy-duty hook-and-loop fasteners.
10. Use compatible inward or outward curved sections for substantial turns and corners.
11. Where a barrier terminates against a wall, install the appropriate left or right gable end and press its sealing surface firmly against the structure.
12. Install optional rear support brackets where additional support is required.
13. Inspect every connection, seal, flap and wall termination before floodwater arrives.

After use:

• Rinse dirt and debris from the panels.
• Use a standard household cleaner if necessary.
• Inspect the seals, flaps and locking mechanisms.
• Allow all components to dry completely.
• Secure the ground flaps in their storage position.
• Stack and store the panels for future deployment.

Site configuration, water depth, surface conditions and anticipated water forces should be evaluated before selecting panel quantities and accessories.

How high is Mayim MAX?

Each Mayim MAX panel stands 40 inches tall. We recommend describing it as suitable for water levels up to approximately 38 inches to maintain a safety margin below the top.

What is the difference between Mayim and Mayim MAX?

Standard Mayim is offered in 20-inch and 30-inch panel heights. Mayim MAX is 40 inches tall and incorporates an extended PVC ground flap and spring-loaded upper locking mechanism.

Are Mayim and Mayim MAX panels interchangeable?

No. The systems have different connection and sealing features and should not be represented as interchangeable.

Are tools required for installation?

No specialized tools are normally required to connect or dismantle the panels. Optional brackets, wall terminations and site-specific configurations may require additional installation planning.

How does the system seal against uneven ground?

A neoprene foam seal runs along the front underside of the panel. The extended PVC flap lies toward the water and conforms to variations in the surface. Adjacent flaps connect with heavy-duty hook-and-loop fasteners.

Can Mayim MAX go around corners?

Yes. Straight panels allow minor directional adjustments. Flexible inward and outward curve sections are available for larger turns; three compatible curve pieces can create an approximately 90-degree turn.

Can the barrier terminate against a wall?

Yes. Left and right gable ends are available to complete a run against a fixed wall. The wall material and surface condition should be evaluated when planning the termination.

How quickly can it be deployed?

Garrison indicates that prepared personnel can deploy approximately three sections per minute, or around 100 feet in roughly 15 minutes under suitable conditions. Actual time depends on staffing, layout, accessories and site conditions.

How much does each panel weigh?

Mayim MAX components generally weigh approximately 32–37 pounds. Exact weight depends on the component.

Can Mayim MAX remain outdoors permanently?

The ABS material is UV protected, but the manufacturer recommends deploying the panels when needed and storing them after the threat has passed.

How should the panels be cleaned?

Rinse away mud and debris after use. A standard household cleaner may be used for stubborn residue. Allow panels, seals and ground flaps to dry completely before stacking.

Will the barrier prevent all seepage?

No temporary flood barrier should be represented as completely watertight. Correct placement of the seals and flaps helps minimize seepage, but surface irregularities, joints and wall terminations may allow some water through. Include drainage or dewatering in the flood plan.
