<p>The invention provides a sandbag having a waist portion. The waist has a smaller cross-sectional area than the remainder of the bag, forming a bag shape that has greater resistance to movement when embedded in the backfill material supported by a sandbag wall. In use, the sandbags with a waist portion are positioned so as to extend from the wall face into the backfill, thus stabilizing the wall.</p> |
