The Mayim™ flood control barrier is an easy-to-deploy flood protection system designed to help protect buildings, facilities and vulnerable areas from rising water. Its durable, efficient design provides a practical solution for preparing for heavy rainfall, severe storms, swelling rivers and flash floods.
Featuring a simple insert-and-lock connection system, Mayim™ flood barrier panels connect securely to create a continuous flood protection wall. The system is available in protection heights of 20", 30" and 40" with the Mayim MAX configuration, allowing it to accommodate a range of flood conditions.
Designed for rapid deployment when flood threats develop, Mayim™ provides a reusable solution for diverting and containing water around important property and infrastructure.

How the Mayim™ Flood Barrier Works
1. Water Pressure Creates Support
As water rises, its weight helps keep the L-shaped Mayim™ barriers firmly positioned. Water pressure pushes the barriers against the ground and adjacent panels, adding ballast, improving the seal and increasing grip.
2. Sealing Helps Minimise Leakage
Foam seals positioned along the underside and edges of the flood barriers help minimise potential water leakage and seepage while the panels are deployed.
3. Designed to Contain and Redirect Water
Mayim™ flood walls are available in 20-inch and 30-inch configurations, while the Mayim MAX system provides protection up to 40 inches. The connected panels are designed to contain and redirect water during severe flood threats.

Simple Mayim™ MAX Set-Up
Stage
Gather the compactly stored Mayim™ MAX barriers and stack them onto a dolly for convenient transport.
Roll the stacked barriers to the required protection location.
Position
Begin connecting the Mayim™ MAX flood barriers from left to right.
Position the L-shaped section so that it faces outward towards the expected floodwater.
Velcro Flaps
The optional flaps are particularly useful on uneven surfaces where additional seepage protection is required.
Unsnap the flaps from the barrier and lay them flat.
Connect the Velcro flaps together to create a continuous protective front.
Connect the Flood Barriers
Tip the flood barrier at an angle and slide the bottom foot connector prong into the receiver loop on the adjacent panel.
Connect the upper sections by locking them together. The spring-loaded mechanism secures the panels in position.
Once the barriers are positioned, connect the lower yellow PVC flap using the Velcro fastening system.
End Gables
To install Mayim MAX End Gables, overlap the final panel in the barrier run onto the corresponding Right or Left End Gable. Position the End Gable firmly against the wall to create a sealed end and help prevent water leakage.
Clamp the top of the End Gable and panel together to secure the connection.
Additional Support for the System
For additional support, an optional metal bracket can be inserted into the rear of the unit.
Insert the bracket into the opening slot on the panel.
Angle the bracket down towards the ground to provide additional support.
