Full Answer

  1. Acquire sand

    Buy coarse-grained sand to make sandbags, or buy ready-made sandbags from a store. Use soil, gravel or clay to make sandbags when sand is not available. Start working on the sandbags as soon as flooding is forecast.

  2. Choose the material

    Make sandbags from grocery bags, pillow covers or compost bags. Sandbags made from polypropylene plastic are an ideal choice because the plastic does not decompose easily.

  3. Fill the sandbags

    Fill the sandbags by hand, or use an automated option to produce many sandbags quickly. Use funnels and bag-holding racks to speed up the process when filling the bags manually. Once the bag is filled, tie the mouth of the bag securely. Ensure each bag is no more than half full and weighs around 40 pounds after filling.

  4. Build the wall

    Dig out a trench deep enough to hold a couple of sandbags. Fill the trench with sandbags. Build a pyramid-shaped wall by stacking two to four sandbags vertically. Ensure that the wall has a wide base and tapers on the top. Place the folded seams of the bags facing the direction of the flooding. Once the wall is in place, stomp on the sandbags to remove any gaps in the sandbag wall.

  5. Cover the wall

    Use plastic sheets to cover the wall for additional protection. Place sandbags in doorways and areas vulnerable to flood water.
