6 Main Types Of Bunding

Bunding is simply a spill containment product, mostly used by businesses which require liquid storage including fuel/oil as well as hazardous materials. You can think of bunding in a sense as a kind of retaining wall. The walled sides provide the barrier to contain spills while still remaining low enough to the ground in most instances for vehicle access. The bunded areas are fashioned for handling the capacity of the biggest spill possible that can occur in that area.
