It can be a cumbersome task finding the best flood barrier for your unique situation when every flood barrier provider you speak to will commonly claim that they have the best flood barrier. In reality, there is no ‘best flood barrier’ because every situation is different. This leaves the consumer in a lonely position of trying to weed through numerous flood barrier options and differing messages of what flood barrier works best to protect their home from flooding.
This is why Flood Defense Group has amassed the largest collection of flood barrier designs in North America, because we understand there is no ‘best flood barrier’ for every situation. We understand that the best flood barrier for your unique situation may depend on a large variety of factors. These factors may include:
Below, is our feedback on the variety of designs and products on the market where we break down the pros and cons of the various systems available.
There are a variety of options when it comes to this type of design and some designs are certainly better than others! Some of the popular options on the market include the Aqua Dam, Tiger Dam, Aire Diversion tubes, and NoFloods Flood Tubes. The primary selling points to these products are that water fill material is cheap and easy making it easy to fill. They conform to the ground nicely, and these barriers are generally less expensive compared to more rigid and robust barriers.
Pros
Cons
Woven Fabric Water Tube – Failure due to UV-Rays
This product earns its name and is our clear favorite ‘water filled flood barrier’, that is completely reusable for violent situations like hurricanes conditions, mud flows, or debris impact. This flood barrier design also has an 8’ tall option with the bragging rights of having the tallest, completely reusable option on the flood barrier market without a requirement to bolt it to the ground. This barrier is tough, which is especially true when comparing it to other water filled flood barriers on the market. It is great a great residential flood barrier as well as being a popular commercial flood barrier with a variety of uses.
Pros
Cons
This flood barrier product is simple and effective and consists of a large air-filled tube that is attached to a ‘skirt’ comprised of a PVC membrane that sits on the ground and conforms well to undulations or inconsistencies. As the floodwater arrives, the weight of the flood water on the skirt, which anchors the product to the ground.
Pros
Cons
DESCRIPTION: These types of flood barrier designs do not require any sort of fill material at all and use the weight or downward pressure of the incoming floodwater to further anchor itself to the ground.
This flood defense barrier is immediately effective against incoming floodwater, and is the fastest to deploy on short notice. It is lightweight, super effective, and stacks away nicely into a corner of your garage or even a closet between uses.
Pros
Cons
If you are looking for a temporary flood barrier that will last a lifetime, this design is a winner. Because they are made of metal, they are extremely robust. This makes them great for arctic conditions, oil and gas facilities, or construction sites with potentially careless employees who may otherwise damage a plastic barrier by simply throwing them around. This product also packs away nicely, making them a great option for the residential market as well.
Pros
Cons
DESCRIPTION: For the ease of describing them, we used the term ‘Airfoil Designs’ because they seem similar to a parachute in design where they raise by themselves as the water level rises. We like this design because they do not require fill material and conform to the ground nicely in creating a seal as the floodwater raises onto the barrier itself.
Pros
Cons
When it comes to linear miles of flood barriers installed, this product is the most widely used flood barrier in the USA for governmental emergency projects and flood protection projects. This flood barrier has all the other flood barriers beat when it comes to stopping power because it is filled with soil and can be configured to about any height and width.
NOTE: There are suppliers in China who claim to sell ‘HESCO’. HESCO is not manufactured in China and products that come out of this area consistently fall apart in the form of degrading geotextile fabric and weld failure of the wire mesh and is of poor quality. Do not be fooled by suppliers who claim to supply this product by name out of China! This has been a big problem!
Pros
Cons
This product can used as a stand-alone flood barrier but, in our opinion, the ability to use this product to reinforce an earthen berm with a long-life span sets it in a category of its own. This product is comprised exclusively of geotextile and therefore, there are no metals or plastics left in the ground. This allows you to build this product, bury it to create an earthen berm that is capable of experiencing overtopping without erosion causing a complete failure should water start cascading down the ‘dry side’ of your barrier.
It is common to use an earthen berm for flood defense, but an earthen berm is not a levee!!!! When an earthen berm is exposed to floodwater, it is common for the soil to become saturated. This can quickly result in erosion/scouring when water is moving laterally along an earthen berm. Additionally, if you have flood water overtop your earthen berm, you can expect the water to quickly erode the soil as it cascades down the dry side of your berm which commonly results in erosion causing a total failure of an earthen berm.
This product can help to stabilize the soil from within your berm against erosion in these situations when exposed to flood water.
COMMON PROTEST – ‘I do not want to lose my view’ (of the ocean, riverfront, or surrounding nature) associated with creating an earthen berm around my property. I also do not want to ‘live in a fish bowl’ by creating an earthen berm around my property. With this product, you can choose to create a low profile earthen berm and if floodwaters are overwhelming, you can build a flood barrier on top of it!!
As a general rule, flood barriers become more expensive as you get taller. For example, a 4’ tall flood barrier can be expected to cost more than twice as much as a 2’ tall flood barrier of the same design which is only half the height. A flood barrier that is twice as high can quickly become more expensive and logistically demanding to purchase, deploy, recover, and store. By incorporating a degree of flood defense landscaping in this manner, you can save time/money/storage space by deploying a lower profile flood barrier on top of a flood defense feature that is landscaped into your property.
Perhaps it is possible to use a soil filled and buried product like Defencell or even raised planter beds to create sections of flood defense landscaping around your property. By doing this, you can also lessen your requirement to purchase/deploy/store flood barriers. For example, you can create a landscaped section of your property where you are not worried about sacrificing your view or the area easily allows for a landscaped flood defense barrier. If you can do this on 1 or 2 sides of your property, you can lessen the cost and logistics of having to deploy flood barriers by 25-50%!! If you are in a flood prone area and/or experience repeated flood events, this can save you a significant amount of heartache over the course of time!
DESCRIPTION: Flood panel systems are in a category of their own and commonly used to protect doors from flooding, protect windows from flooding, or oversized openings such as protecting a garage from flooding. They are also used for key areas like protecting elevators from flooding, power generation areas, and similar infrastructure than you cannot afford to be submerged in floodwater.
These systems are more expensive than traditional, removable flood barriers but do a great job in quickly sealing off a door from flooding (for example).
Generally speaking, we categorize them into two categories which are flood panels that wedge themselves into a door frame like Flood Gate by Quickdams, Dam Easy Flood Panels, or ‘RAPID’ flood barriers and panels that are inserted into pre-mounted brackets that need to be installed by inserting nuts, bolts, or rails into your door frame like the Legacy Flood Panel, RAPID flood barriers, Flood Logs, EZ Panel, or the FRA Panel.
Pros
Cons
NOTE: If you are trying to lower your flood insurance rates, some regulations require you to alter the structure by physically installing the barrier to your home by using bolts or brackets to be considered an ‘improvement to your home’. Because these wedge systems only need to be wedged into a doorway to work, there are no modifications or ‘improvements’ to your home because the barrier is not physically attached to the structure. Therefore, no improvement has taken place. However, you may be able to simply attach a bracket to either side of a doorway, which the barrier is then wedged in between, to constitute an improvement and subsequently be accepted by an insurance provider. This technique, as wall as all information within this review, is up to the reader or end user to investigate or endorse as Flood Defense Group assumes no liability or responsibility for any suggestions or claims made in this review.
These flood panel systems are comprised of various materials but generally speaking, most of them are made from aluminum panels. These systems can achieve greater heights of protection than most wedge systems and can be stacked to achieve about any height required. They tend to span longer distances, but depending on the depth/width of flood protection required, intermediate, removable upright posts may be required.
Pros
Cons
Water Filled Flood Tubes – These are generally the least expensive option for flood protection. However, once you get above about 20” of a protective height requirement, the cost savings become more trivial and we find some of our other barriers to be preferable.
HESCO – This soil filled barrier proves to be the least expensive option in achieving greater heights for flood protection which becomes more profound the higher you go.
NOAQ Boxwall, Geodesign Flood Barriers, and Inero Flood barriers – The fact that these products do not have to be filled with any sort of fill material to work makes them among the quickest and easiest to deploy.
HESCO (or similar) – This product is the undisputed leader in achieving great heights for flood protection because this product is easily stacked to achieve a desired height.
MUSCLE Wall – When it comes to a removable, and completely reusable flood barrier, the Muscle Wall product takes this category.
For this category, we find most of these barriers to be reusable and find it easier to discuss products that seem to have a diminishing return on the ability to reuse them which would be and of the soil filled barriers like HESCO (or similar), Defencell, and traditional sandbags.
We also believe larger Water Tube systems (20”+ in protective height) are not as easy to reuse and often purported. This is especially true for Water Tube systems that have multiple membrane layers like an outer protective layer and inner tube.
Through the course of use, and reuse, Water Tubes tend to experience punctures (which are generally repairable) and can be heavy to work with due to residual water weight inside between uses. These products often develop small punctures when drug across rough surfaces like concrete, thorny surfaces, and even ‘twiggy’ weeds and grasses that are not soft like sod-type grasses.
NOAQ Boxwall, Geodesign Flood Barriers, Inero Flood Barriers, Airfoil Designs and NOAQ Tubewall perform well on the logistic front with a tolerable performance by Water Tubes. This is predominately because they package away well into a small cube as far as storage space and shipping expense.
During a flood event, the water table is above the level of the ground the flood barrier is sitting on. Therefore, you can expect water to be working it’s way under any flood barrier. For a quick passing flood event, this is generally not a problem but…..if you are expecting flood water for an extended period of time, you can expect wetness on the ‘dry side’ of the flood barrier. Over time, depending on how much space there is between the flood barrier and the structure being protected, this could prove problematic.
Also, water may be falling from the sky, and draining off your roof which will also start to accumulate. Watch for this and if possible, try to make sure your gutters drain onto the ‘wet side’ of your flood barrier.
Depending on the size of the pump you get, they are generally expensive and worth having if the accumulation of water on the ‘dry side’ of a flood barrier is unacceptable.
Also, if you have to evacuate and the power is likely to go out, it may be worth investing in a generator capable of keeping a pump running while you are away.
If your home is getting ready to flood and you do not have flood barriers, you still have options for do-it-yourself flood protection!!
This YouTube video below shows how you can cover a flood barrier with plastic to create a water-tight seal against water. However, if you do not have a traditional flood barrier, you can use this same concept and cover about anything with plastic. Your ability to hold the water back will be related to the weight or rigidity of what you are covering with plastic.
For example, let's pretend you only have 10’ wide rolls of plastic to protect your home against 2’ of floodwaters. You can attach the plastic about 3’ up the walls on the outside of your house and this leaves you 7’ of extra plastic which you then lay out on the ground in front of your house. You then must secure this plastic to the ground such that incoming floodwater can get on top of the plastic and not be allowed to get under the plastic. This gives you a 7’ of an impermeable membrane that will drastically slow down the ability of the flood water to seep under barrier and into your home.
IMPORTANT RULE WHEN USING PLASTIC -
Plastic must be against your heavy object or some sort of backing and not be required to support the water weight!! It is only an impermeable layer of protection and it is the weight or rigidity of the surface it is covering that actually stops the water!
Methods to keep plastic secured to the ground or the structure it is attached to may include:
These may not be ideal scenarios but….you can do something and you are simply trying to keep the water away long enough for the flood waters to recede.
As an ex-infantryman, I am a strong believer in multiple lines of defense and if a stupid idea works, it may not be a stupid idea!! Keep the faith and keep fighting!!! It’s not over until it’s over and every little step you can take, may make the difference in keeping your home dry and avoiding the devastating effects of floodwater in your home!!!!!!!
