After wrapping an opponent in sand or Iron Sand with either the Sand Binding Coffin or Sand Drizzle, the user causes it to implode and crush whatever is within it. According to Gaara, when used to kill a person, the death is so quick that there isn't even time for the victim to feel any pain. The pressure also produces a sizeable fountain of blood. Gaara can control the pressure used in the attack, which allows him to either break bones or completely liquefy an opponent.
Using a pun common to Gaara and his techniques, "sand waterfall" (砂瀑, sabaku) is pronounced the same as the Japanese word for "desert" (砂漠, sabaku).
