Where Can You Buy Sandbags?

So, where can I buy sandbags? If you’ve never looked for them, you probably have no idea where to buy sandbags for flooding. The good news is they are pretty easy to find. 

You can find them at almost any hardware store and big-box home-improvement stores, and you can buy Sandbags Online like these from Amazon.

What is the Best Type of Sandbag?

When most people think of sandbags, they usually think of the old-school burlap sacks used for centuries. But you can choose from plenty of other materials, and we’ll explore those options.

There are numerous types of sandbags, and before deciding which bag to get – you’ll first need to determine what you’ll use it for and where you will be placing the bags. Here are a few of the different types of sandbags manufactured.


Polypropylene bags are made of sturdy plastic-based material. They aren’t biodegradable, so they last significantly longer than the original burlap sacks that most people are accustomed to using. Polypropylene means they are great for use for prolonged periods.

UpNorth White Polypropylene Sand Bags

The durable nature of Polypropylene allows you to place these bags in direct sunlight for extended periods without worrying about them rotting.

If you expect to keep them in direct sunlight for long periods, you might want to check out the polyethylene sandbags below, which have a higher UV rating.

Polypropylene is the type of sandbag used by the military for flood control and use on the rifle range.  

And they’re inexpensive to buy, about $1.00 each, like those from the Up North Store.

Durasack Sandbags

DuraSak sandbags may be the way to go if you want longevity. They can be filled up to 50 pounds and have steel bag ties to ensure the sand stays where it belongs.

Burlap Sacks

Burlap sandbags are probably the most common type of sandbag you will come across. They are the least expensive sandbags, which goes a long way when you have tons of area to cover.

Burlap sandbags are 100% biodegradable and environmentally friendly. These are the best sandbags if you need to cover a lot of ground or have a limited budget.

Quick Dam (Sandbags)

Here’s the one you’ve probably never seen or heard of Quick Dam. It isn’t necessarily a sandbag, but it does act like one and is still an excellent flood deterrent.

They are self-activating – and portable, and when wet – these sandless ‘sandbags’ help stop water from penetrating your home.

Best of all, no labor is involved since you don’t have to fill the bag with sand. Each can absorb up to 4 gallons of water, expand to 3.5 inches, and last up to eight months.

Video:  Check out how Quick Dam is revolutionizing flood control.

The Quick Dam product is a great way to divert water during storms and floods. You expose them to fresh water and let the self-activating absorbent powder soak up all the moisture. But beware, these are not used for use with saltwater.

Once saltwater comes into contact with them, a chemical reaction causes the bag to leak. That is why you only use these in freshwater. They do work with snow as well!

How to Use Sandbags For Flooding

There are a few different ways your home could flood, from cresting rivers to breached flood barriers to failing sump pumps and the obvious one – Rain Storms. So why are sandbags such a favorite way to stop flooding?

Sandbags are inexpensive, simple to use, and easy to set up. Also, with today’s technology, sandbags are getting better.

All it takes is some sand, a shovel, and an extra set of hands; voila, you’ve got a makeshift fort for your home to keep the water where it belongs on the outside of the house.

We’ve all seen the damage floods are capable of, and nothing is more frightening than sitting and watching while the water rises toward your property

Fire is the only thing potentially damaging your home or business more than water.

How To Fill Sandbags

Figuring out what type of sandbag you should use – is only the beginning of the sandbag experience. The hard work begins now because you get to fill them up. You’ll likely need a little extra help from a friend.

Get Yourself to the Sand

Many municipalities bordering Rivers with High Flood Plains tend to have ample sand for residents’ use.

While we always recommend that you use sand to fill your sandbag with (after all, that is why they are called sandbags), if sand isn’t available, then you can use soil – in a real pinch, although for a lot of reasons, it is not our first choice.

Don’t Overfill Sandbags

Make sure you don’t overfill the bags with sand. Otherwise, they won’t close tight or stay intact when you stack them on top of each other, resulting in loads falling over when you need them in place the most.

However, If you underfill, they won’t be nearly as effective at stopping the water from entering your house.

When it’s complete, the perfect amount of sand is between 30 to 40 pounds. Depending on the bag size, you can easily stack the bags effectively.

The sandbags will be malleable enough to stay where they belong – while still being able to effectively hold back the water you’re trying to keep out of the house.

Cement Sand Bags (For Semi-permanent flood control)

You may not want to use sand or soil, and that’s fine too. Instead of using that, you could also fill the bags with cement. But do understand that you aren’t filling the pack with cement only. Instead, you will need to use a mixture of sand and cement.

It’s a pretty straightforward process. All you need to do is fill the bag at a three-to-one ratio. That means three parts sand to one part cement. Of course, once you are done filling the sandbag with the proper balance, you will also have to fill it with water.

Once you’ve got a perfect consistency, you can rest assured that your sandbag fort will keep water from entering your house, saving you a lot of cash.

Frequently Asked Questions (FAQ)

How Do You Stack Sandbags?

Stacking sandbags properly is just as important as filling them correctly, and to stack them correctly, you can use a “Standard Stack” or “Pyramide Stack Method. If you stack them incorrectly, your house could flood without the sandbags. And with all the labor you put in to fill the bags, that would be a waste of time.

It would help to remember that sandbags don’t offer a completely watertight seal. Thankfully, when you stack the sandbags correctly, they are an excellent tool for minimizing water intrusion or damage — provided they’re stacked correctly. 

Standard Stack Method – Home Entry doors or Garage doors

If you have ever seen a brick wall, you have seen how you should stack your sandbags for flooding. First, you must lay down a line of sandbags, but the second row doesn’t merely go directly on top of the bag in the first line.

Instead, put the second stack of sandbags in the middle of two bags (this will help you to pack them tightly so that water doesn’t get between the sandbags).

Stacking your sandbags is the last line of defense between your home and the flood trying to overtake it, so take a little extra time to lay them correctly.

How Do Sandbags Keep Water Out?

Sandbags keep water out by employing the “Sand Principle.” As an example, Have you ever built a sandcastle before? If so, you know the only way to get the castle to stand alone is to mix the sand with water. But why is that?

The answer is pretty simple, which is the sand principle. Once water hits the sand, it binds it, turning it into a firm and somewhat water-tight substance — the same concept goes for a sandbag blockade.

Once the water hits your sandbags, the sand absorbs it, swells, and firms up.

Are Sandbags Reusable?

Sandbags are not meant to be a permanent fix and are not designed for long-term use or as reusable material. Sure, they are great for keeping your house free of flooding during severe storms, but that is a one-time use.

Once you have used sandbags to prevent water intrusion, it is best to dispose of the old ones.

After your sandbags have been used, filled with sand, or any other substance, storing them for future use (even if they still look like they are in good condition) may result in you having faulty sandbags that are incapable of keeping your house from flooding.

Instead, it would be best that you properly dispose of the sandbags. We understand that you may want to throw them in the trash, but because of exposure to flood water, they have probably been in contact with chemicals and other wastes that are harmful to the environment.

Rather than keep them in your trashcan, you can find out how and where to throw them out by searching your city’s guidelines on Google: “getting rid of used sandbags.”

How Do You Prepare For a Flood?

Sandbags for Flooding - Where to Buy and How to Use in 2019

Follow the steps in this article and learn where to buy, how to fill, and how to stack sandbags, and you will find yourself prepared for a flood.

Preparing for a flood means taking immediate, preventive measures to keep your home from flooding. How often do we worry about our living rooms filling up with water? Probably few do, and if so, very seldom.

However, if you’re here, you likely live in an area prone to flooding. Please don’t wait until the last minute to start prepping your house for flooding. It can occur much quicker than most people realize.


We could all learn from those who didn’t prepare for flooding. Common sense suggests purchasing as many sandbags as possible during the flooding seasons.

You’ll be ready once a severe storm arrives – and before the floods begin.  

Quick Reminder:  Just as grocery stores quickly run out of bottled drinking water in an emergency, stores will likely run out of sandbags once a big storm is on the way.

Plan, and allow yourself plenty of time to fill all the sandbags and stack them where necessary. You, your property, (and your family) will be happy you did!
