BUND (noun) pronunciation: [buhnd] - "A secondary enclosure, typically consisting of a wall or berm which surrounds a tank or fluid-handling mechanism, intended to contain any spills or leaks"
Bunding, also called a bund wall, is the area within a structure designed to prevent inundation or breaches of various types.

The term can also refer to dikes, but it is frequently used to describe liquid containment facilities that prevent leaks and spillage from tanks and pipes, though sometimes any barrier is referred to as bunding. Frequently, the liquids in tanks and pipes are toxic, but bunding is used to prevent the liquid from causing damage (either by force or its chemistry) If a large tank has a catastrophic failure, the liquid alone can cause extensive damage.
Bunding is a legal requirement in many countries particularly around tanks, storage vessels and other plant that contain liquids which may be dangerous or hazardous to the environment.

Prenco's Bunding solutions offer portable/flexible as well as fixed options for that "wall" "dike" "barrier" to contain any fluid. A variety of terminology is used....
