Sandbags For Flood Control
The Garrison™ sandbag is designed for a variety of flood control and overall protection needs around homes, municipal buildings, infrastructure and equipment. Sandbags are suitable for all types of floods and for water redirection, water retention and containment.
Garrison’s sandbags are 14” x 26” and use a 6mm thick, 10x10 thread, polypropylene fabric. This fabric incorporates 2.5%, 1600 hour UV protection for added life. Garrison commercial grade sandbags are manufactured with durability and effectiveness for floods in mind. Each bag is double stitched at the bottom to increase strength and has tie strings to close the bags. Garrison bags are standard in size and weigh 35-40 lbs when full.

Protect Against Flooding
Garrison sandbags are versatile in their protection ability and many be used for many important applications. Vulnerable areas around homes, municipalities, riverfronts, waterfronts and other important infrastructure require protection that will withstand the pressure of heavy flood waters. Sandbags are great option for heavy duty and flexible protection. We recommend sandbags for…
Doorway Protection
Levee and Berm Construction
Loading Dock and Lengthy Garage Entryways
Sewer and Drain Protection
Water Diversion and Retention
Weighing down and securing temporary fences, tarps, signs and all types of objects.
Where can I use Sandbags?
Erosion Control
Use as a long term solution for coastal and agricultural areas to prevent erosion
Levees, Dikes & Berms
Construct levees, dikes and berms quickly and effectively using sandbags
Earthbag Homes
Use sandbags to create earthbag and earthen homes.
Flood Control
Stop flooding in its tracks and protect vulnerable property areas
Force Protection
Well suited for military fortification with their durability and use of local fill
Ballast
Sandbags are 35-40lbs when full, providing ballast and support
Why Garrison™ Sandbags?
Looking for an Alternative? Check out the Minnow.
In addition to traditional sandbags, Garrison offers the Minnow™, gel filled sand bag alternative. Minnow bags swell when exposed to water, and absorb water to inflate.
Stackable
Create higher barriers of protection with stacking

Frequently Asked Questions?
-
-
The Garrison sandbag is manufactured using high quality 6mm thick, Polypropylene material with a 10x10 fabric weave.
All Garrison sandbags are UV protected for 1,600 hours to protect against material degradation.
-
Garrison™ sandbags are 26”L x 14”W x 4”H (when filled).
Each sandbag has a traditional sand bag “pillow” shape.
Weight when filled to recommended Capacity is 35-40 lbs.
Weight of the sandbag when full is 60-75 lbs (We recommend only partially filling bags, rather than overfilling to capacity, to allow better stacking and to prevent gaps that will allow seepage of water).
-
It typically takes 600 bags to build a 100ft wall that is 1ft tall (using a base width of 2-3 sandbags).
Depending on the strength of the wall needed, you can build walls using a base that is 2x or 3x the height desired. So a 2ft high wall at 100ft long, would require 2100 sandbags at 3x the height and 1700 sandbags at 2x the height.

-
For erosion control applications, we suggest using gravel, however for flood control applications, sand is considered the best fill material.
1 cubic yard of sand will fill approximately 100 - 14” x 26” sandbags. Each sandbag will hold about 0.4 cubic feet of sand when filled to the recommended amount.
-
Sand is typically available at local home improvement centers as well as at local masonry and construction supply stores, rock quarries, landscaping centers, and crushed stone suppliers. For larger applications, local suppliers will usually be able to deliver sand or gravel in bulk, using a dump truck.
-
We recommend using a #2 rounded point shovel, with a D grip and a straight shaft as this fits best with the opening size of the sandbags.
We suggest always using gloves when filling sandbags, to protect your hands.
Two people, using a shovel, can usually fill and tie off between 12-15 bags per hour. Mechanical bag filling machines can usually fill approximately 5,000 bags per hour.

-
The sandbag itself is water permeable, but the sand fill contained in the bag is effective at stopping and redirecting water. When stacked, sandbags are extremely heavy and are able to withstand the rush of oncoming water and storm surges. The key to an effective sandbag levee, dike, or dam is to stack bags with a base 2x-3x the height of the wall needed. For extreme flood protection applications, it is ideal to create as wide a base as is practical.
-
Yes! Sandbags are ideal for weighting down the legs of temporary fencing, holding tarps in place, and providing additional ballast for signage, tents and more.
-
An Earthbag house is a structure built with sandbags. Earthbag construction starts with using fill material found at the construction site to create structures which are both strong and can be quickly built.
-
Two people working together with a shovel and tying off the bag (assuming integrated ties) can usually fill and position 12-15 sandbags per hour. It would take 2 people between 45-50 hours to fill and position enough bags to build a 100ft long dike that is 1ft high with a recommended 2ft width (or 2 bags wide).

-
When a Garrison™ sandbag is filled to the recommended capacity, it should weight between 35-40 lbs. If filled full each bag will weight between 60-75 lbs.
Note: We recommend only partially filling bags, rather than overfilling to capacity, to prevent gaps that will allow water leakage.
