Spill Containment

The correct Storing, Handling & Dispensing of fluids to help prevent spills is a high priority today. Meeting the many legislative and quality standards such as the General Environmental Duty, ISO 14001, Australian Standards and the Australian Dangerous Goods code requires certain measures and equipment to be in place. Silverback has sourced an extensive range of quality, high performance products that offer "best practice" and safety advantages when storing and handling containers of fluids.

These help ensure that drums and containers are stored correctly at your premises and when dispensing and decanting operations take place, they are done with the assistance of the right safety item - all with the goal of spill risk reduction and compliance with those standards.


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.

Silverback's Bunding solutions offer portable/flexible as well as fixed options for that "wall" "dike" or "barrier" to contain any fluid.
