Sandbag Stacking Q&A
There are two sandbag stackingmethods:
1.Herringbone pattern stacking: Theupper and lower rows create a zigzag pattern with one slanting left and oneslanting right.
If the first layer is stacked fromthe right, the second layer is stacked from the left. Each bag should overlapits adjacent bags by 1/3 of the bag's surface area.
2.Brick-wall pattern stacking: Sandbags arestacked up with each bag covering 1/3 of the surface areas of the bags beneathit.
Things to particularly payattention to when stacking sandbags:
Lay tarpaulin (tarp) on the mostinner layer of the sandbags to prevent seepage.
If there are lumps of hard sand inthe sandbags, please crush them by striking or rubbing them.
When stacking sandbags, the bagsneed to be supported by objects placed behind them so that they don't topple.
When stacking a single row: Theopening of the bag must face inward, while the bottom of the bag must facewhere the water comes in.
When stacking double rows: Theopenings of the two rows of bags should face the middle to prevent the bagopenings from being burst open by water.
After use, sandbags must bereturned (to district or village offices) to avoid environmental pollution.
Where is it important to havesandbags?
Accessways to buildings; outside of thebasement's transom windows.
Please note that if the front dooropens to the outside, the sandbags should be stacked inside the front door; ifthe front door opens to the inside, the sandbags should be placed outside thefront door to avoid obstructing the exit.
How high should sandbags bestacked?
The height of the stack may be 1.5to 2 times the height of previous floods to effectively block the water.
