Sandbagging: What You Need to Know

Sandbagging is a simple and effective way to reduce or prevent flood damage to your property. When installed correctly, sandbags can help divert water away from homes and protect vulnerable areas during rising water conditions.

What You’ll Need

• Sandbags (heavy-duty, woven bags)
• Sand (preferred) or soil if sand is unavailable
• Plastic sheeting (vapour barrier)
• Shovel and gloves

Filling Sandbags

• Fill bags only 1/2 to 2/3 full (approximately 35–40 lbs)
• Tie bags if they need to be transported; otherwise fold the top over
• Do not overfill, as this prevents proper sealing between bags

Safety Tips

• Wear gloves and closed-toe footwear
• Lift with your legs, not your back
• Avoid twisting while carrying bags
• Work in teams or use a brigade line to move bags efficiently

Where to Place Sandbags

• Build sandbag walls at least one metre away from your home where possible
• Avoid placing bags directly against foundation walls
• Use natural elevation on your property to your advantage

How to Build a Sandbag Wall

1. Prepare the area: Remove debris, snow, or ice
2. Dig a shallow trench: This helps prevent water from seeping underneath
3. Lay plastic sheeting: Extend it under and behind the wall
4. Place sandbags:
   • Lay the first row tightly in the trench
   • Stack bags in staggered rows (like bricks)
   • Ensure no gaps between bags
5. Build to proper size:
   • Wall should be wider than it is high (ideally 2–3 times wider)
6. Seal the wall:
   • Fold plastic over the completed wall and secure with additional bags

Important Notes

• Sandbag walls may still leak; be prepared to pump water from protected areas
• Floodwater may be contaminated—handle used sandbags with care
• Sandbags are not a permanent solution and should be disposed of properly after use
