Sandbags 2
Using sandbags to prevent overtopping of existing levees and for retaining flood waters where no back-up material is available
INSTRUCTIONS
 Fill sandbags 1/2 to 2/3 full but leave enough flap to turn under. Ends can be left open.
- For heights of 1 foot and less, lay 3 single courses with sacks lengthwise as shown in sketch "A" below.
- For heights greater than 1 foot, place as indicated in sketch "A" .
 When bags are placed, flatten out and fill voids by mashing bags with feet and vigorously tramp each course of the levee section. This is an extremely important operation for providing a levee which will be as impervious to water as possible and to insure stability of section. Loosely placed sandbags improperly keyed together may result in failure and cause serious damage.
LEVEE SECTION
For heights in excess of the above (approx. 3'-6') hold same batter and build on the side as indicated by dashed lines above. Alternate header course (bags placed crosswise) and stretcher courses(bags placed lengthwise)
ESTIMATING DATA: Average weight of each filled sandbag, approx. 50 lbs. and approx. 1000 sandbags are required for each 100 sq. ft. of surface (height multiplied by distance).
