Quick Dam Sandless Sandbags are instant sandbags that expand in size when water is added to them.  When considering any sandbag alternative, it is important to look at differences in functions, features to decide what product is right for you. 

Packaging of Quick Dam Sandless Sandbags and FloodSax

Here you see the packaging of Quick Dam flood bags in the package of 6 compared to FloodSax package of 5.  Quick Dam demonstrates its compact packaging, while FloodSax are in a larger vacuum sealed bag.

Upon opening the individual bags, the difference in dimension and polymer filling is very apparent (which enables the sandbag to instantly inflate).  FloodSax is the larger, white colored bag, whereas Quick Dam is the smaller black colored bag.

 FloodSax / flood sacks are much larger in size and contain more super absorbent polymer filling, which makes them 25% larger than other sandless sandbags on the market.

Quick Dam Flood Barrier Review vs FloodSax Sandless Sandbag Alternative

On the left you will see that the Quick Dam Flood barrier bag has very little polymer filling, while the white FloodSax sandbag alternative had an evenly distributed filling.

*Its USPTO patented design allows of the FloodSax to stack higher sandbags, therefore building some of the highest flood barrier walls. (It won't slip and slide off each other... like other instant sandless sandbags).

The filling inside these bags are exactly what gives them their weight and volume to protect against flooding disasters and indoor water damage.  FloodSax polymers are more evenly distributed in the bags because of its unique patented 9 chamber design.  Quick Dam flood barrier bags have all the polymer set in a corner of the bag (one must shake and spread out the contents to evenly distribute contents).

Here both the Quick Dam bags and the Flood Sacks are folded.  This comparison allows a visual demonstration of the amount of polymer contents of each bag.  Clearly Quick Dam flood barrier products have less filling, when compared to FloodSax sandbag alternatives.

Review on the amount of Polymer Contents in Quick Dam Flood Barrier product

Why is it important to compare the amount of filling content of the instant sandbags?  The very polymer is what inflates the bag, which is used to fight flooding disasters and also is used as the absorbent for leak and spill applications.  The more the polymer filling in the flood bag, the more volume capacity the bag has to 1) divert flowing waters 2) fight flood waters and 3) the more water/liquid it can absorb.

The photo of the Quick Dam Flood bag next to FloodSax says it all.  Although the price point of a Quick Dam sandless sandbag is less than that of a FloodSax / flood sack, one can clearly see that one is getting less material and content to absorb liquid and fight floods, leaks and spills.

 Here we review how a Quick Dam Flood Barrier product, the Quick Dam sandless sandbag inflates with fresh water (not with salt water).  This bag inflates unevenly to one side, because the polymers are in pillowcase like bag, where the contents are in one large section.  The result of such a simple design allows the polymer content to slip and slide around in the flood bag, making it NOT ideal for stacking flood barrier walls.  Additionally, there is more time spent evening out the bag, by pushing the contents around to distribute the polymers.

When pulling out the Quick Dam sandbag alternative right out of the fresh water bucket, the result is a lopsided bag.  Time and effort needs to be taken to flatten out and evenly distribute the bag's content.

After the Quick Dam instant sandbag is padded down by hand to distribute the polymer contents, one can see that the bag's average height is only 2-3 inches high.  2 to 3 inches in height is very low, when compared to standard sandbags.

Here is an image of both the inflated, water-filled sandless sandbags side by side.  The Quick Dam sandbag alternative is longer, but shorter in width than the FloodSax flood bag.  From the photo of the Salt water barrier compliant FloodSax (Quick Dam is NOT salt water barrier compliant), you can see outline of the patented design of the Flood Sack.  With the 9 chamber internal design, the FloodSax inflate fairly evenly and do not require extra time and effort to even out the bag and its content.  It is designed to build high flood barrier walls and do not slip and slide off one another when stacked high.

Here is a zoomed up photo comparing the height of the two bags next to each other.  FloodSax is about double the height of the Quick Dam sandless sandbags.

Weight and Volume of Instant Sandless Sandbags

The flood protection capabilities of a sandbag is based on its weight and volume.  Since the weight and volume capacity of sandless sandbags are based on 1) the size of the bag and 2) its crystal polymer fillings, it is safe to say that the heavier the bag, the more powerful it is against indoor and outdoor water protection.  Here are the numbers:

  • 1 FloodSax bag weighs 1.5 lbs
  • 1 Quick Dam bag weighs 0.5 lbs

From these numbers and the images, it is clear that FloodSax offers greater flood water and liquid damage protection.  

Benefits of FloodSax Flood Barrier bags

1) Greater flood protection area coverage (protect more property)

2) Builds higher more stable flood barrier walls

3) Soaks up more liquids for greater leak and spills / water damage protection.

The image above illustrates the shear height difference in flood protection between FloodSax and Quick Dam. 

Illustration shows flood bags  stacked 2 bags high, with 10 bags across the bottom and 11 bags stacked and staggered on top.

To sum, FloodSax® flood bags / flood sacks offers superior flood barrier wall protection when compared side by side to the Quick Dam flood barrier sandless sandbags.
