Our Standard Sandbags Pack Light, Deploy Quickly, and Stop Water

St. Boniface sandbags are an ideal flood prevention tool:

  • They’re durable, made with tight-woven polypropylene that’s dense and resistant to punctures and tears, and they can hold any dry material.
  • They’re inexpensive and designed to last, with UV protection for prolonged deployment.
  • They’re easy to use for homeowners, municipal, and industrial bulk-use alike.
  • They’re lightweight and packable for easy, inexpensive transport and storage when or where they’re needed.
  • They’re the perfect size, at an industry-standard 14” x 26” for bulk-fill applications and redeployment in almost any application.
  • Available in white poly and UV-resistant orange.

Applicable Across Tough Settings

Poly sandbags are remarkably versatile, and our customers span industries and use-cases. They’re ideal for barricade stability, erosion control, flood prevention, and in common ballast situations. 

Infrastructure and Municipalities

When flooding strikes, poly sandbags can be filled and deployed quickly to reroute water and create critical retaining walls. Municipalities frequently keep our sandbags on-hand in bulk for deployment as needs arise. Sandbags can be used not only for water control, but also for erosion prevention and in supporting banks, and they can even be effective in spill containment.

On The Jobsite

Contractors and site supervisors commonly deploy our sandbags for ballast as anchor bags––in holding down signage and tarping, and to prevent erosion at large and small sites alike. They’re also used in landscaping for filtration, separation, and protection purposes, and they’re frequently used in lighting and grip settings in the entertainment industry.

In the Energy Sector

Our customers include the oil & gas industry, which commonly use our sandbags in water control situations, erosion prevention, as well as in unique pipeline and extraction settings.

By Homeowners

Homeowners frequently deploy our sandbags as ballast, like weighing down pool covers over off-season months, tarping during construction projects, holding basketball hoops in place, and restraining canopies during outdoor events. From sandbags for raised garden beds to stream and slope stabilization, we’ve seen it all.

Effective, Economic Sandbags For Water Control

When filled and stacked properly, sandbags can keep bulk water out incredibly efficiently and economically. Filled sandbags have been used for decades in water control, and St. Boniface poly bags are a modern take on what has now become a standardized implement for government, municipal, and individual water damage prevention.

With St. Boniface bags, building a sandbag water barrier is easy. 

  • Sandbags are filled to half- or three-quarters full, allowing bags to “mold” to the contours of their surroundings. This can be done rapidly with machine assistance or by hand.
  • Sandbags should be stacked on an alternating pattern to create a resilient, water-resistant seam. Staggered stacking avoids continuous joints where seepage can occur along long barriers.
  • For short-term events, we hear from customers who empty and store sandbags for future use, too.

FAQ:

Q: What are sandbags? 
A: Sandbags are heavy-duty bags made from woven materials, typically polypropylene or burlap, that are filled with sand or other materials to create a barrier against water, soil erosion, or other hazards.
 
Q: What are the common uses of sandbags? 
A: Sandbags have a variety of uses, including flood control, erosion control, construction, landscaping, military defense, and as weights for temporary signs or tents. They are also commonly used in emergency situations to protect property and people from flooding or other natural disasters.
 
Q: What makes St. Boniface Bag Company’s sandbags unique? 
A: At St. Boniface Bag Company, we take pride in our sandbags for their superior quality and durability. Our sandbags are made from high-quality woven polypropylene material that is tear-resistant and UV-stabilized for long-lasting performance. They are designed to be easy to fill, tie, and stack, and come in various sizes to suit different needs.
 
Q: How do I fill and use sandbags properly? 
A: To fill sandbags, place the bag on the ground, fold the top flap over, and shovel or pour sand into the bag until it is about half full. Then, fold the top flap back over and tamp the sand down to remove air gaps. Repeat the process until the bag is full, and then tie the top with the provided ties. To use sandbags, stack them in a staggered pattern, overlapping the bags to create a solid barrier. It’s important to place them tightly against each other to prevent water from seeping through.
 
Q: How many sandbags do I need for flood control? 
A: The number of sandbags you need depends on the height and length of the area you want to protect, as well as the anticipated water level. As a general guideline, it is recommended to use at least two rows of sandbags for effective flood control, with the second row staggered behind the first. The height of the sandbag barrier should be at least one to two feet higher than the expected water level. It’s always best to consult with local authorities and follow their recommend and follow their recommendations for flood protection.
 
Q: How long do sandbags last?
A: The lifespan of sandbags depends on various factors, including the quality of the material, exposure to weather conditions, and frequency of use. However, St. Boniface Bag Company’s sandbags are made from high-quality materials and are designed to be durable and long-lasting, providing reliable performance for extended periods when properly stored and maintained.
 
Q: Can sandbags be reused?
A: Sandbags can be reused in certain situations, depending on their condition. If the sandbags are not damaged or contaminated, they can be carefully emptied of sand, cleaned, and stored in a dry place for future use. However, it’s important to inspect sandbags for any signs of wear or damage before reusing them to ensure their effectiveness.
