Sand Brick Technologies has redesigned the the lowly sandbag, making it easier to use and more effective.
Believe it or not, the opening on a sandbag is 2 inches smaller than the average shovel blade. How annoying! The Sand Brick is 2 inches *wider* than a shovel.
The Sand Brick has angled ends, allowing the bags to interlock and thus increase wall strength. They are smaller - only 25 lbs instead of the 40 lbs for a sandbag.
They are made of solid plastic, so contaminated flood water can't get in. So many intelligent improvements.
