Colors: Availability varies by model; MB2 is offered in red and hunter green

Accessories and exact panel quantities vary according to the selected system and site layout.

Mayim barriers are designed for tool-free deployment by facility, maintenance or emergency-response personnel.

Deployment steps:

1. Identify the area to be protected and determine the expected direction of the water.
2. Transport the stacked panels to the deployment area by hand, dolly, pickup truck or forklift, depending on the size of the system.
3. Begin at the left side of the planned barrier run.
4. Position each panel with its L-shaped foot 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 locking tabs.
7. Continue connecting panels until the required barrier length and configuration are complete.
8. Use compatible curved panels where tighter turns or corners are required.
9. When terminating the barrier against a building, use an appropriate gable end or another manufacturer-approved sealing method.

The surface should be inspected before deployment. Remove loose debris and sharp objects that could interfere with the underside seal. Mayim performs best on a firm, reasonably even surface.

After use, rinse away dirt and debris. Household cleaners may be used for stubborn residue. Allow the panels to dry completely before stacking and storing them.

Actual deployment requirements vary with barrier length, layout, site conditions and the accessories being used. Personnel should review the complete manufacturer instructions and practice deployment before an anticipated flood event.

How much water can a Mayim barrier hold back?

The 20-inch MB1 is designed for water levels up to approximately 19 inches. The 30-inch MB2 is designed for water levels up to approximately 29 inches. A separate 40-inch Mayim MAX system is available for higher water levels.

Are tools required for installation?

No tools are normally required to assemble or dismantle standard Mayim panels. The panels connect using an insert-and-lock system.

What is the difference between Mayim and Mayim MAX?

Standard Mayim is available in 20-inch and 30-inch models. Mayim MAX is a separate 40-inch system that uses a flexible PVC ground flap and spring-loaded locking connections. Components should not be assumed to be interchangeable.

Can Mayim go around corners?

Yes. Straight panels permit small directional adjustments. Inward and outward curved sections are available for larger turns and corners.

How does the barrier seal against the ground?

Neoprene seals are positioned along the underside and adjoining sides of standard Mayim panels. As water rises against the L-shaped barrier, the water pressure increases the downward and outward force on the system.

Can the barrier connect to a wall?

Optional gable ends can terminate a barrier run against a fixed wall. Their foam sealing surface can help accommodate materials such as brick, concrete block or stucco. Site conditions should be reviewed when planning the connection.

Can Mayim be reused?

Yes. After deployment, rinse the panels, remove any dirt or residue and allow them to dry completely before stacking and storing them.

Can the barriers remain outdoors permanently?

Mayim panels are UV protected, but the manufacturer recommends deploying them when needed and dismantling them after the threat has passed.

How quickly can Mayim be deployed?

Garrison indicates that prepared personnel can connect approximately three sections per minute, or deploy roughly 100 feet in about 15 minutes. Actual deployment time depends on staffing, layout, access and site conditions.

How do I determine how many panels and accessories I need?

Panel quantities depend on the required length, barrier height, number of turns and wall connections. Provide site dimensions, expected water depth and photographs when requesting a system recommendation.
