Overview & Best Uses
Overview & Best Uses
The Mako™ Inflatable Flood Barrier provides fast, reusable flood protection for doorways, entryways, windows, hallways, garages and other defined openings. Unlike permanently installed flood panels, Mako installs without drilling, mounting channels or structural modifications.
Mako is constructed from reinforced drop-stitch PVC that becomes rigid when inflated. Its dual inflation chambers expand the barrier against the sides and bottom of the opening, while specialized rubber gaskets help create a secure seal against suitable mounting surfaces.
The barrier can be deployed in approximately five minutes using the included hand pump or a compatible regulated air pump. After the flood threat has passed, Mako can be deflated, folded and stored compactly for future use.
Standard models are available in 30-inch and 40-inch protection heights with multiple widths to fit common openings. Custom barriers are also available for openings requiring different dimensions.
Key Features:
• Protects doorways, garages and other defined openings
• Available in 30" and 40" protection heights
• Multiple standard widths available
• Custom sizes available by quote
• Dual-chamber pressure-fit design
• Reinforced drop-stitch PVC construction
• Installs without drilling or permanent mounting hardware
• Deploys in approximately five minutes
• Deflates for compact storage
• Durable and reusable
• One hand inflation pump included with each barrier
Mako must be correctly sized for the opening and installed against suitable solid surfaces. Measure the actual space between the mounting surfaces—not simply the nominal door size—before ordering.

Setup & Installation
Setup & Installation
BEFORE ORDERING
- Measure the clear width between the surfaces that will support the barrier.
- Measure the available mounting depth on both sides of the opening.
- Confirm that the floor and side surfaces are solid, reasonably smooth and structurally suitable.
- Select a barrier that matches the opening width and desired protection height.
Measure within approximately ½ inch. If the opening is not perfectly straight or plumb, err slightly larger rather than smaller.
INITIAL PREPARATION
When the barrier is first received:
- Remove it from the shipping box and unfold it.
- Inflate it to approximately 2 PSI.
- Leave it inflated for approximately 24 hours to help straighten seals and folds created during shipping.
- Deflate it before completing the first installation.
INSTALLATION
- Clear dirt, debris and obstructions from the floor and sides of the opening.
- Remove the barrier from its storage bag and unfold it near the opening.
- Partially inflate both chambers to give the barrier enough structure for positioning.
- Place the barrier inside the opening with its sealing surfaces evenly aligned against the floor and sides.
- Press downward to remove slack and establish contact with the lower surface.
- Inflate the upper chamber to secure and stabilize the barrier within the opening.
- Inflate the lower chamber to establish the bottom seal.
- Confirm that the barrier is centered, stable and in continuous contact with the mounting surfaces.
- Install any included anchoring straps when required for wider barriers.
Inflate each chamber to the manufacturer’s recommended 12–15 PSI. Do not exceed 15 PSI.
AFTER USE
- Deflate and remove the barrier.
- Clean off dirt, debris and contaminants.
- Allow it to dry completely.
- Fold the barrier and return it to its storage location.
- Inspect the barrier, valves and seals before its next use.
FAQ
FAQ
HOW DO I SELECT THE CORRECT MAKO SIZE?
Measure the clear distance between the actual surfaces against which the barrier will press. Do not rely solely on the stated width of the door or garage door. Also verify the available mounting depth and select the desired protection height.
WHAT IS THE DIFFERENCE BETWEEN THE 30-INCH AND 40-INCH MODELS?
The height represents the barrier’s protection height. Select the 40-inch model when the anticipated floodwater level or site conditions require greater protection. Taller barriers may be thicker and require additional mounting depth.
DOES MAKO REQUIRE PERMANENT INSTALLATION?
No. Mako uses inflation pressure and friction to secure itself inside the opening. Drilling and permanent mounting channels are not normally required.
IS AN INFLATION PUMP INCLUDED?
Yes. One hand inflation pump is included with each Mako barrier purchase. Additional or replacement pumps are available separately.
CAN I USE AN ELECTRIC AIR PUMP?
A compatible regulated electric pump may be used. It must allow the user to monitor and control the pressure. Inflate the chambers to 12–15 PSI and never exceed 15 PSI.
HOW LONG DOES INSTALLATION TAKE?
A Mako barrier can generally be deployed in approximately five minutes once the user is familiar with its placement and inflation process.
WHAT SURFACES CAN MAKO SEAL AGAINST?
Mako can be installed against suitable solid surfaces such as concrete, wood, brick, metal, asphalt, stone and tile. Smooth, level surfaces generally provide the best seal.
CAN IT BE INSTALLED ON PAVERS OR GRAVEL?
Pavers, gravel and other porous or uneven surfaces are not recommended because water may travel underneath or through the surrounding surface.
CAN IT BE INSTALLED BETWEEN DRYWALL SURFACES?
No. The pressure required to secure the barrier could damage drywall or other weak mounting surfaces.
ARE CUSTOM SIZES AVAILABLE?
Yes. Custom barriers are available for openings that cannot be protected with a standard model. Custom units require accurate opening measurements and a quote.
IS MAKO REUSABLE?
Yes. After use, clean and completely dry the barrier before deflating, folding and storing it. Inspect the valves, material and sealing surfaces before redeployment.
WILL THE BARRIER PREVENT ALL WATER INTRUSION?
Performance depends on proper measurement, sizing, inflation, placement and the condition of the surrounding surfaces. Because incidental seepage may still occur, a drainage or dewatering pump can provide useful secondary protection.
FAST FLOOD PROTECTION WITHOUT PERMANENT MODIFICATIONS
Mako is designed for locations that need dependable opening protection without permanent posts, channels or mounting hardware. The barrier expands within the opening and uses controlled air pressure to create a rigid flood wall and secure perimeter seal.
Once the flood threat has passed, the barrier can be removed without leaving permanent hardware attached to the building. Its lightweight, foldable design also makes it easier to transport and store than many rigid flood-panel systems.
ACCURATE MEASUREMENT IS ESSENTIAL
Mako fits between the surfaces that support and seal the barrier. Measure the clear width from mounting surface to mounting surface rather than measuring only the door itself.
For example, a door may be described as 36 inches wide, but the opening where the barrier will actually sit may measure 40 inches. In that situation, the barrier should be selected based on the measured 40-inch opening.
The opening must also provide adequate mounting depth. Smaller barriers generally require approximately 2.75 inches, while wider or taller barriers may require approximately 4 inches. Very large custom units may require approximately 6 inches.
For best performance, confirm that:
• Both sides of the opening are solid and structurally sound
• The floor is reasonably smooth and level
• Major cracks, gaps or damaged surfaces are repaired
• Water cannot easily travel underneath porous pavers or gravel
• The barrier will not press directly against drywall
STANDARD AND CUSTOM-SIZE OPTIONS
Choose from standard 30-inch and 40-inch heights with multiple widths. If the required dimensions are not offered as a standard selection, request a custom-size quote.
Custom Mako barriers are available up to 48 inches high and 192 inches wide. Please provide:
• Clear opening width
• Desired protection height
• Available mounting depth
• Mounting-surface material
• Photos of the opening
• Any unusual floor slopes, gaps or obstructions
PUMP INFORMATION
One hand inflation pump is included with every Mako barrier purchase. Additional hand pumps may be purchased separately for replacement purposes or for facilities deploying multiple barriers at the same time.
