How To Build a Sandbag Wall

  • Fill sandbags approximately half full. If bag is too full, it becomes too rigid to fill in the gaps of the sand bag wall.
  • Use Super Sacks (bulk fibc totes) as a quick bulk option for a sand bag wall.
  • If needed, use plastic wrap within each layer of the sand bag wall to protect any water leaking through.
  • Calculate the total sand needed by multiplying the number of bags by 35 lbs
  • 1 Cubic Yard of Sand weighs 2,700 lbs = ~80 bags filled ~35 lbs
