Muscle Wall
Muscle Wall is a modular, high-strength interlocking barrier that is filled with water for ballast, allowing it to stand against rushing or standing water without heavy machinery. Its L-shaped, patented toe design uses the water’s own hydrostatic pressure to anchor the wall to the ground.
The system deploys far faster than sandbags — a small crew can install roughly 100 feet in about 30 minutes, and it can be placed even after floodwater has begun to rise. It is reusable event after event: pull the plugs, drain the water, and pack the segments down for storage.
- Uses
- Flood control and water diversion
- Stormwater management and runoff control
- Primary and secondary containment for industrial sites
- Construction-site perimeters and roadways
- Erosion and sediment control
- Emergency flood response
- Benefits
- Reusable – Drains, packs down, and redeploys event after event.
- Robust – Stands up to wave action, high winds, and flying debris.
- Scalable – Configurable across a range of heights to suit the site.
- Self-anchoring – Patented toe design uses hydrostatic pressure to hold its footing.
- Rapid deployment – About 100 ft in 30 minutes with a small crew and no heavy machinery.
Maintenance & Storage
After use, the segments are drained, rinsed, and stored for the next deployment.
Eco-dam
Eco-dam is a reusable, fast-deploying water-filled flood barrier and temporary cofferdam, fabricated from high-tensile fabric and PVC with high-frequency-welded seams that are both waterproof and gas-tight.
Its twin-chamber design, separated by an internal partition, locks the unit in place under uneven water pressure to prevent rolling while letting water move freely inside. It fills and drains on site without heavy machinery and is factory pressure-tested.
- Uses
- Property and perimeter flood protection
- Temporary cofferdam / dry work areas on construction and river sites
- Creating temporary reservoirs
- Benefits
- Reusable – Deploys, drains, and packs away for repeated use.
- Fast deployment – Installed by a few people with no heavy machinery.
- Stable – Twin-chamber, anti-roll design resists movement under load.
- Watertight & gas-tight – High-frequency-welded seams for structural strength.
Maintenance & Storage
Drained and rinsed after use, then folded down for compact storage and transport.
Rapid H2O
Rapid H2O is Defender’s flagship barrier: a compartmentalized, steel-reinforced, water-filled system engineered to handle multiple water and hazard scenarios from a single reusable product.
It is faster to place than sandbags, can be driven over, shaped around corners, and joined to any length. Built for a multi-decade service life, it is redeployed rather than sent to landfill.
- Uses
- Flood protection
- Spill response and containment
- Water diversion
- Wildfire applications
- Benefits
- Multi-use – One system covers flood, spill, diversion, and wildfire.
- Reusable – Multi-decade design life; redeployed, not sent to landfill.
- Driveable – Can be driven over where site access requires it.
- Flexible layout – Shaped around corners and joined to any length.
- Rapid – Faster to place than sandbags.
- Steel-reinforced – Compartmentalized, water-filled construction for strength and stability.
Defender Flood Wall
Defender flood barrier is a portable, freestanding flood barrier designed for rapid deployment in urban environments, on hard surfaces such as tarmac, paving, and concrete. It can be extended to any desired length.
Available in two heights, Defender flood barrier can effectively divert floodwater up to 0.75 meters. Each box section weighs less than 4 kg for a 0.5-meter section, making the system incredibly easy to set up. The barriers remain stable without any external fastening, relying on the weight of the floodwater itself to keep them in place, even at full height.
Defender flood barrier is especially effective during flash floods, quickly managing fast-moving water and redirecting it away from vulnerable areas, such as entrances. The sections simply rest on the ground, allowing water to be diverted.
The system is constructed by linking together box sections, and the flexible ±3° coupling enables the creation of curves. Specific corner pieces allow for inward and outward angles as needed.
After use, Defender flood barrier units can be quickly disassembled and cleaned with a garden hose. The stackable design ensures they take up minimal storage space and are easy to transport.
- Uses
- Single access points and driveways
- Individual buildings through to full residential and commercial developments
- Rapid-response flash flood diversion
- Temporary flood protection for construction sites
- Containment of mains water bursts and pollution incidents
- Benefits
- Lightweight – Quick and easy deployment by a single person.
- Rapid setup – Low weight allows faster installation, helping protect more property in less time.
- Stable – Designed to stay firmly in place, with friction and water pressure providing secure anchoring.
- Flexible – Suitable for curves and corners using custom corner sections, and capable of bridging small steps with dedicated gable sections.
- Space-efficient – Compact when stacked, requiring minimal storage space and easy to transport.
Corner Support
Defender flood barrier curve sections allow the creation of both inward and outward corners, making it possible to fully enclose and protect contained areas from flooding.
Maintenance
After use, Defender flood barrier can be quickly dismantled and cleaned with a standard garden hose.
Storage
Defender flood barrier sections are stackable, requiring minimal storage space and allowing for easy transport. Units can be palletised to meet customer requirements. As a guide, a standard timber pallet holds approximately 26 Defender flood barrier sections (around 16 metres), while a 40-foot container can accommodate up to 1 kilometre.
Acquastop
Aquastop is a made-to-measure, pressure-fit flood barrier for individual openings such as doors, garages, shopfronts, and windows. It seals an opening using a compression system that requires no permanent rails, profiles, or drilling.
Because it fits within the opening’s own reveal, it can be put up by one person in moments and removed cleanly for reuse, leaving the building’s appearance unchanged when stored away.
- Uses
- Domestic and commercial doorways
- Garages
- Shopfronts and shop windows
- Windows, hoppers, and drainage grids
- Single access points
- Benefits
- Made-to-measure – Manufactured to fit each opening exactly.
- Fast – Deploys in seconds by a single person.
- No building work – No permanent rails, profiles, or drilling required.
- Reusable – Packs away and reuses event after event.
- Watertight – Compression seal holds firmly against the opening.
Floodmatik
Floodmatik is a fully automatic, passive flood barrier that requires no power and no human intervention. During normal use it sits hidden and flush within a doorway or threshold.
As floodwater rises, the barrier lifts on its own buoyancy to form a watertight seal before water reaches the threshold, then lowers itself back into place once the water recedes — protecting the property whether or not anyone is on site.
- Uses
- Domestic doorways (new build or retrofit)
- Commercial entrances and access points
- Properties needing always-ready, unattended protection
- Benefits
- Automatic & passive – Operates on water buoyancy, with no power or attendance.
- Always ready – Protects when you are away, asleep, or on holiday.
- Self-stowing – Returns flush and hidden after the flood recedes.
- Low maintenance – No motors, sensors, or electrical parts.
- Accessible – Flush installation maintains level and wheelchair access.
IBS
The IBS demountable flood protection system erects a temporary flood defence wall to protect against flooding while leaving the landscape largely unchanged during normal conditions. It is used for community flood protection, road and railway closures, industrial and commercial premises, and coastal flood-protection schemes.
In principle the system consists of two mobile components: centre support posts, set at regular intervals and bolted onto permanently pre-installed anchor plates, and aluminium dam beams that stack between the posts. Beams can be partially installed for lower flood levels.
- Uses
- Community flood protection
- Road and railway closures
- Industrial and commercial premises
- Industrial and commercial premises
- Single access points
- Benefits
- Lightweight – Aluminium posts and beams for easy transport and installation.
- Quick to install – Simple assembly with minimal tools.
- Long lifespan – High-quality materials for durability.
- Free-standing – Posts support flood heights up to 3 m.
- Flexible levels – Partial beam installation for lower flood levels.
- Fully planned – Complete logistics planning provided for each system.
Flexibility
Suited to straight defence lines and curves — for example a radius of 20 m or more at 2 m post spacing, or 30 m or more at 3 m spacing, with special corner posts for tighter bends. It accommodates ground slopes up to 5%, overcomes local surface unevenness up to 15 mm via a special ground seal, and uses height transition pieces to bridge steps or level changes.
Erection & Dismantling
A 100 m straight wall with 3 m post spacing and a 1.2 m protection height takes approximately 1 to 2 hours for 4 to 8 instructed workers to install. Dismantling — including removal to storage and cleaning — takes about twice as long.
System Variations
IBS BSH-I 50 (50 mm beams) for applications up to 1.5 m; IBS BSH-I 100 Light (100 mm beams) up to 3 m; and IBS BSH-I 100 (100 mm beams) up to 5 m.
Storage
Stored contact-free in stackable galvanised steel pallets fitted with lifting points, tension belts, and forklift positions; beams and posts can be rinsed off with a water hose after use.
Defender Floating Tank Top (DFTT)
LIID Energy & Water Conservation Systems are floating, modular hexagonal covers for frac pits, storage tanks, and clean-water supplies, for which Defender is the exclusive dealer. With an R4 insulation value, they cut heating costs in cold conditions and block nearly all evaporation in hot, dry, or windy conditions — reducing trucking, transfer, and water costs. The covers float with changing water levels, deter birds and other wildlife, and are fully reusable, repairable, and easy to clean, with a modular design that conforms to any pit or tank size or shape.
