Flow Defence products are passive flood barriers which require no human intervention to activate. The flood barrier will rise into position from buoyant forces by intercepting flood water at the crest of the driveway (or other ground surface) and storing it in an underground channel before water can enter the underground carpark.
Flow Defence (FD) flood barriers intercept floodwater only when it reaches the crest of the driveway and will therefore not open prematurely. With ~10mm of water depth over the 6000mm wide grated inlet, the interception chamber will fill in just over 60seconds raising the barrier whilst filling.
Warning lights mounted on either side of the barrier illuminate and flash during operation.
SEALING MECHANISM
The Flow Defence flood barrier is a self-contained unit where the collection channel also houses the barrier.
The barriers sealing operation is all done from the downstream side of the channel which allows full unrestricted access to the upstream side of the barrier for maintenance where optional pre-screening baskets can also be installed.
The seals remain above water level as the barrier is displaced and the sealing mechanism becomes watertight before floating debris can be caught between the barrier and sealing frame
A key feature of the design are angled lugs that guide the seals during compression and act as a canter lever point by providing a fixed connection between vertical barrier supports and the concrete chamber. This configuration reduces barrier deflection from hydrostatic forces.
RETAINED FLOODWATER
The FD barrier will remain in the upright position until flood waters recede and the collection channel is drained.
The barrier can be lowered using one of three methods:
• Submersible pump installed within the FD channel collection sump. This is activated by a float switch, draining the pit automatically and lowering the barrier provided power is still available to the site during a flood event.
• The self-siphon system will prime when flood water fills the collection channel. A tamper proof valve (valve with no handle) can be open after flood water recedes. The retained water captured by the FD interception channel will then be drained into the underground carpark (~3,000L) lowering the barrier at the same time.
• Any pump on a maintenance vehicle with a suction hose can access the FD interception channel by removing access grates from the property boundary at ground level. Water in the collection chamber can then be discharged to the street kerb or landscaped area while lowering the barrier.
MAINTENANCE PROCEDURES
Flow Defence flood barriers should be de-sludged using an educator truck after every flood event in which the barrier activates. The barrier is not required to be removed during maintenance. The sealing mechanisms are located below ground level and are out of direct sunlight minimising any environmental or impact hazards.
• Advise all concerned parties of the proposed date and time of cleaning.
• Obtain approvals from the appropriate authorities.
• Prepare necessary Safe Work Method Statements.
• Provide barricades in working areas and signs to prevent injuries to public or staff.
• Remove inlet grates.
• Lower vacuum hose, remove debris and sediment while cleaning all components with a high pressure hose (most Wet Vac combination trucks have this facility).
• Remove vacuum hose and replace inlet grates.
• Record site location, date and time of clean and duration of clean.
INSPECTIONS
We believe that the unit life will be enhanced significantly by using Flow Defence staff to monitor and maintain the flood barrier.
Flow Defence flood barriers should be inspected (half yearly) and serviced (annually) to ensure they are clean and free from material buildup.
6 Month Inspection:
• Interception channel sump inspected for material build up (water, sediment or debris).
• Flexible seal and guide frame inspection.
• Full maintenance report.
• Determine if service is required.
Cleaning After Unit Operation:
• Remove sludge and sediment using Vac Truck.
• Clean components with high pressure spray.
• Flexible seal and guide frame inspection.
• Full cleaning report.
If you require further information or details about our competitive inspection, cleaning and reporting service please contact Flow Defence.

Coastal cities may need something like this for preparation on Tsunamis and Hurricanes.
You should do this evrywhere
that music reminds me of Oceans 11 when they explain how the heist will work lol
I have no idea why, but I enjoyed this video. I have no purpose or even potential purpose for this. But I liked it.
Not true. I live near a creek that has a major floodplain on my property. Would you guys install out in the middle of a rural space? Probably connected to a barn? It will be a few years, but If I have flooding issues, I might use your services.
Don’t care
I'm pretty impressed with your smart design. A question about maintenance . Would dust/small rocks from the driveway jam the system? Especially the sliding component. Another question is in a minor flood event where the flood water is just marginally higher than the basement ramp entrance, will the flood gate still raise up to max height?
Hi, rocks and dust will go through the grate and drop to the bottom of the chamber and collect in the sump for periodic removal, easily accessed by removing the grates. The sealing mechanism is always above water level, so as the barrier is raised, it is not effected by the debris. The flood wall raises to its full height every time it is activated.
So remind me how trapped drivers are gonna get out with the water pressure
The barrier will prevent the garage from flooding. If the road is flooded it would be unwise to drive in it, your vehicle would be safe in the garage until flood water recedes.
That makes no sense how will that go back down with water still in it
Hi Matt, there is a float activated submersible pump inside the chamber which drains water after the flood event, it also keeps the chamber dry so if only a small amount of water enters the chamber the barrier wont go up just a little bit and sit there.
Flow Defence but where does the water go?
It just gets pumped back into the street kerb where it came from
matt kontos wouldnt the water flow from under it to the other side i mean it ahows in the video the water can get behind it
The water cant get behind, there is a seal on the downstream side which prevents it.
Sure, but won't water flow under the door to the garage?
The open surface area on the downstream side of the barrier is relatively small and the sump pumps in the basement could easily handle the flows.
This barrier is good for the flood protection
Very cool system.
2 questions,
1) What material will be used?
2) If it floats won't it tumble/fall/break?
1) Aluminium internal frame, high density polyethylene outer surfaces and polyurethane foam to fill the voids
2) No, the barrier canter levers against the concrete chamber
flood water comes with debris and soil, need to remove panel to clean out the sediments after the flood.
The chamber can be cleaned without removing the barrier, there is full unrestricted access under the grates to the bottom of the chamber for a vacuum hose and jet spray.
What if people have to get out of the garage but its flooded?
The barrier will prevent the garage from flooding. If the road is flooded it would be unwise to drive in it, your vehicle would be safe in the garage until flood water recedes.
Im trying not to offend someone but why the f you drive your car when there’s flood. You will destroy your car.
You swim.

And yourself
No one park their boat there
Pretty neat invention.
Idk why but I read it like "Food Water Berrier"... might be because I'm hungry...
If the flood was higher than the barrier , what will happen ?
The barrier height is set based on historical flood levels (and allowing for sea level rise if on the coast) or from flood modelling studies that have been completed in the local area.
Ok c cool sa protége nos parking mais si il pleut sa monte ?! Donc c pas pratique même si le concepte est bien
It doesnt make sense to me, isnt it better to flood the parking garage and avoid more water going to the city? Garage could be pumped out afterwards...
and what about all the cars in the garage? also, the amount of water in the garage is minor compared to the overall flood, so it's not going to help any by letting it get flooded.
Hi...do you have franchise in India??
Do you have something in India?
I don’t know why this is in my recommendations but it’s a nice concept
But what if the water gets over the barrier?
The barrier height is set based on historical flood levels (and allowing for sea level rise if on the coast) or from flood modelling studies that have been completed in the local area.
What if it just rains in there a few days?
Or a flow limited drainage pipe so that the flood defense only activates when there are big quantities of water coming in.
LET'S MAKE A 50 METER WALL AROUND THE BASEMENT GARAGE
What if it rained.
Can it reach up to 2.5 m high or more?
2.4m is easy for transport to site, larger will need some assembly onsite
so what happens if you have a flood of 1 meter + 1 cm.. barrier is useless
The barrier height is set based on historical flood levels (and allowing for sea level rise if on the coast) or from flood modelling studies that have been completed in the local area.
so what you're saying is if historically speaking the area has a 2 meter rise. the barrier will be put to 2 meters. I get that. but you didnt answer my question.. Let me rephrase it. Lets say I live in a flood area where every year I have a 2 meter flood. I buy your product to cover that. But let's say one year we have worse flooding where I have a higher flood. Does your company use a Current plus potential model when choosing the barriers you install? Do your barriers have a scalable aspect included or would it have to be completely replaced as now the new historical model has a 2.2 meter rise? Im sure your company has a contract to replace the model if it gets damaged, does that contract also include replacement if the barrier needs to be replaced due to a higher rise?
We do not size the barrier, the client does, they could request a 3m barrier in a 1m flood plain if they like, its about balancing cost and allowing for adequate freeboard.
What if it rains relly bad tho
There would be pumps there Trying to stop the flood no matter what is in it's way
The barrier would have to be in the entrance of the parking garage
No shit.
What happens if a tree falls on it
Depends on the size of the tree, there is excess buoyancy designed in the barrier that could lift decent size branches. If the barrier was already up most trees that line the street would have little effect.
thats cool
Rains can activate it?
There is a float activated submersible pump inside the chamber which drains water after the flood event, it also keeps the chamber dry so if only a small amount of water enters the chamber the barrier wont go up just a little bit and sit there.
do you have a way to bring this to australia?
Flow Defence was founded in Australia
Flow Defence oh
Good job lmao
Гениально
cant u just install drains...
Drains in basements are too low to discharge into the stormwater network, but even if they could there would be too much water in the network and it would surcharge back into the basement. There are sump pumps installed in basements but they are not large enough to displace all of the water that can enter from the driveway.
Impressive
The Conservative i
also its only 1 m high

Well if people were not lazy and cleaned the storm drains then you probably wouldn’t need to do that
Stormwater drains are not designed to convey major storm events, the roads are overland flow paths.
Flow Defence aaahhh
The final point for rain water is the sea, so the flow off the land is governed by the tides and wind. A high tide backs up the rivers, this coupled with heavy and/or persistent rain, results in a flood. So it doesn't matter how clean the drains are if the water has no where to go.
Open ground will soak up some of the rain water but will reach saturation point, this open ground is reduced every year by building projects, roads, and sealed parking areas etc. So again the water has no where to go.
There is an answer for this in the way of holding ponds and tanks. that fill during a rain storm and then the storm water is released during dry periods.
Some cities have large diameter tunnels to take this water, Kuala Lumpar Malaysia have the Smart Tunnel that doubles as a car toll tunnel. London is building a storm tunnel under the River Thames and is up grading the sewer system.
The barrier is a good idea for basement areas, and of course needs to be designed to stop the highest recorded flood height with some spare capacity for wind driven surges and traffic wash.
Wouldn't it be pretty easy for dumb kids to put stuff in it though. Does this cool invention pose a threat to stupid kids sticking there hand into it? That all sounded really sassy but I'm just curious.
Kids could jam sticks into the grate but it wouldnt stop the barrier from rising and there would be less chance of sticking their hands in the wrong place compared to an electric gate.
I don't know how I got here, but very clever... there should be an insurance discount for the owner(s) of the building for installing this...
I can imagine peopl bringing river water just to fill this for fun.
Won't work, the system keeps trying to pump out the water that's causing the barrier to rise.
It's convenient that the water level never goes higher than the wall. 😂
The barrier height is set based on historical flood levels (and allowing for sea level rise if on the coast) or from flood modelling studies that have been completed in the local area.
You know what...
That's a fair point. +1
couldnt they at least make it the same height as the wall for extra half meter?
The animation is for concept purposes, to minimise cost of installation the barrier is sized to suit expected flood levels which may or may not be the height of the wall.
I like how they answer your comments
Really like this :P we need this in florida....also you should make it so you need to press a button for it to go up and down rather than it on its own...because what if its just a super rainy day :P
Thanks for your comment, we are currently looking at some installations in the US and yes you can just fill the barrier up with water from a tap if you wanted it to raise before an approaching rain event.
Flow Defence ah ok tnx for the fast reply and the answer :
@@FlowDefence cam you buy this product is the u.s
This is an amazing project.
i've seen it before.pretty handy.
Nice .. very useful ... ✌️✌️✌️✌️✌️
I like how the flood just stops as it reaches 1 meter... XD

Preciso saber se vocês vem na casa da gente está lá moro em Governador Valadares Minas gerais
How could something be light enough to float but string enough to hold back all that water weight
Displacement (Archimedes' Principle), the metal frame inside the barrier weighs less than the water that is displaced by the toe at the bottom of the barrier, like a ship.
The force of water raising the barrier does not need to be resisted and so sliders in that direction allow flow, at the maximum raising point the barrier is pressed into a locking position, bracing for horizontal pressure
Eu moro em Governador Valadares e rente
This Cool 😎
Cool
This is very smart i hope this will become a product.
Thank you, this is a product, we are currently manufacturing and installing.
How does it deal with debris that gets through the screens? Sand could be a problem if you are situated next to a river.
That is a great question, floating debris is no problem because the seals stay above the water level until the barrier is raised and the seals compress. There is a sump below the barrier that can store sinking debris/sand until after the flood event. One of the key features of this design is the unrestricted access from ground level to the bottom of the sump where a vacuum hose can be used for debris removal without having to remove the barrier, unlike other similar devices.
Put an angle on the bottom of the sump towards one side and most of the debris would get collected there rather than coating all of the base. On the example here, i could be angled towards the street so you can lift the grate and vacuum it out more easily. Throw in some water to assist if necessary to wash the remaining debris forwards.
Yes you have a good grasp of the procedure, the useful thing with vac trucks is that they can apply high pressure water while they vacuum which can easily dislodge and mobilize any debris in the sump while it is being sucked out of the chamber.

Quero saber o valor dessas peças de barragens Pará portas e portão de garagem
Buona idea ma completamente poco efficace' poiché funziona a pressione idraulica con acqua deve impedire il passaggio oltre il metro e mezzo' e soprattutto prima dell’installazione controllare l'oscillazione della falda idrica e la sua estensione altrimenti rimane solo una buona idea……
Preciso saber qual é o valor e portão
*SO KEWL!*
Cat lol
Hi,i'm from indonesia. Do you have sales representative in indonesia?
Do you already have representatives in Brazil?
Hi,not yet but we are working on it.
interessou também? rssr
I want to purchase it in India, how it's possible please help to get it.
Can I get the permission to copy some parts of this video?
Is there actually a true working model....even at just one place?....where this is installed and working?
Yes we have many installations in Australia
I want this and I am happy for this day
another benefit:
does not use electricity
It needs electricity for the pump that's part of the installation.
Yes to drain the chamber and lower the barrier but not to activate and raise it.
It’s actually “minimising electrical usage” that is the benefit
I don't think it's about minimizing the electricity usage, the important point is reliability. That gate will come up, even if power is down.
Can you make it like that but it very long & height, just say America-Mexico border, the wall will trigered by movement, so when people walk. Near it the wall will rise so they cannot pas
Pair this with a generator thats under the barrier, and you could generate electricity for places with intense flooding. Of course nothing that would keep warmth, but enough to keep the lights on.
A few years ago I had an idea of a mechanical levee and I drew it but it looked like something you would find in a sci-fi show.
what happens if it gets stuck because of all that dirt accumulated in the parts for years ?
Can we get it in India..
Porno music rocks
What software do you use for animation cause I'm a student and needed to make an animation similar to this.
What happens if the barrier thought it was rain but it was tornado
How this wall rising... What is the mechanism behind it.?
これ、日本でもある程度の広さを有する道路や敷地の仕切りに設置を義務付けるべきだろ。
散々ゲリラ豪雨だ堤防決壊だと騒ぎまくってるんだから。
This is like Magic wall what harry pootis made
Nice.
and what about this system when it rain?
Well first of all let's say we dont have a flood
But it's raining and the water raises the bar, how will cars enter then if it's only raining
Good Idea but i think this will be more effective on a coastal area at a larger scale rather than in the city underground parking lots
The barrier is located at the crest of the driveway so water will only enter in large volumes when the road starts over topping. There is a float activated submersible pump inside the chamber which drains water after the flood event, it also keeps the chamber dry so if rain enters through the grate the barrier won’t go up just a little bit and sit there. If more water enters the chamber than the pump can displace, the barrier will raise.
Ok y’all didn’t put into factor that if it’s just pouring down rain let’s say like hurricane Harvey. What if that water goes over the barrier
The barrier height is set based on historical flood levels (and allowing for sea level rise if on the coast) or from flood modelling studies that have been completed in the local area.
How does it go up? I mean with which material is it made? I'm going to start engineering studies and its interesting

... when rain ...
just use flex tape
nice and good this barrier, but behind the barrier can also form water. Since it is not covered
The open surface area on the downstream side of the barrier is relatively small and the sump pumps in the basement can easily handle this flow. Its the huge surface flows on the road that the barrier is preventing from entering the basement.
Looks like it's still too low

What happens when it goes higher are there any larger sizes for the dam?

Flow Defence cool
I'm lost, if it simply floats, what prevents it from raising when it rains? I
Hi Luke, its located at the crest of the driveway so water will only enter in large volumes when the road starts over topping, however, there is a submersible pump that keeps the pit empty should a small amount of water get in. If more water enters the chamber than the pump can displace, the barrier will raise, this large volume of water would have been headed for the basement.
Hmmm😑 what a ubout the that rain that would fall in the pit and fill up?
There is a float activated submersible pump inside the chamber which drains water after the flood event, it also keeps the chamber dry so if only a small amount of water enters the chamber the barrier wont go up just a little bit and sit there.
Looks like a really bad idea. Prevents egress when flood waters are still relatively low, so anyone/anything trapped behind will be guaranteed to drown if it is breached.
If water has reached the crest of the driveway it is not relatively low, it would be about 350mm deep on the road. When it breeches the driveway crest the basement will flood without some sort of barrier to prevent it.
If you can't swim and you're in a flood high enough to exceed historical levels, it probably doesnt matter where you are in that area
Umm wouldnt it still get flooded since the top part is still open?
The open surface area on the downstream side of the barrier is relatively small and the sump pumps in the basement can easily handle this flow. Its the huge surface flows on the road that the barrier is preventing from entering the basement.
and if the water goes for more than 1m you are just so fcked up xD

After flood. barrier gates retain original position how?

What is the purpose of this the water is still inside
I dont understand your comment, please expand.
What about flash floods
Even flash floods build up, the chamber fills and raises the barrier in about 60-90 seconds.
It sure looked like the water was going to go over that
