Prevent flood by sandbags: big and small bags

You’re smart to think about using both big and small sandbags for flood prevention! It can be a very effective strategy. Here’s why and how:

Why Use Both Big and Small Sandbags?

• Big bags for the bulk of the barrier: Large sandbags are great for creating the main structure of your flood barrier. They hold a lot of sand, making them efficient for building up height and width quickly.
• Small bags for sealing and fine-tuning: Smaller sandbags are more maneuverable. They’re excellent for:
  • Filling in gaps and irregularities in the ground.
  • Creating a tighter seal around doorways, windows, or other vulnerable areas.
  • Building up specific areas where extra height is needed.

How to Use Them Effectively

1. Plan your defense:

   • Assess the flood risk: Where is the water likely to come from? How high might it get?
   • Identify vulnerable areas: Doorways, windows, drains, low-lying areas.
   • Decide on your barrier strategy: Will you build a wall? Divert water? Protect specific areas?

2. Prepare your sandbags:

   • Use good quality bags: Burlap or woven polypropylene are common.  
   • Fill them properly:
     • Big bags: Fill about 2/3 full for easier handling and conformity.
     • Small bags: Fill slightly more, as they’ll be used for finer adjustments.
   • Don’t tie the bags: The weight of the sand holds them in place.  

3. Build your barrier:

   • Clear the area: Remove debris where you’ll place the bags.
   • Lay a plastic sheet (optional): This between the bags and the area you’re protecting can create a better seal.  
   • Start with big bags: Place them lengthwise, parallel to the expected water flow. Overlap them like bricks in a wall.
   • Use small bags to fill gaps: Tuck them into any spaces between the big bags or where the barrier meets the ground.
   • Build up height: If needed, use the pyramid method, setting each layer back slightly. Again, use small bags to fill any gaps as you go.

4. Protect specific areas:

   • Doorways and windows: Use small bags to create a tight seal against the bottom. You might even place a large bag across the opening and use small bags to build up the sides.
   • Drains: Cover them with a plastic sheet and then sandbags to prevent water from backing up.

Important Reminders

• Sandbags are not foolproof: They help, but won’t guarantee 100% protection.  
• Combine with other measures: Clear gutters, install flood barriers on doors/windows, etc.
• Safety first: Wear gloves, lift bags carefully, and don’t work alone.
• Don’t reuse contaminated bags: Dispose of them safely after the flood.

By using a combination of big and small sandbags, you can create a more adaptable and effective flood defense system. Good luck, and stay safe!
