Economical design offers cost savings and secure spill containment. There are applications where our Containment Berms are used all day / every day with frequent vehicular and personnel traffic. And other applications where the Berm is only set up when needed. And still, other applications where a container (drum, IBC, equipment, etc) is placed in the Berm and left there for long periods of time. It is for the second and third situation that we designed the Economy Model Containment Berm. As the name states, this product is less expensive than most other models so it may not offer all of the conveniences that some of them do. But rest assured, it is rugged, durable and packs plenty of its own features.
