In the 1970's Expandi developed the self inflatable oil containment boom. This was one of the very first of its type, and Expandi is one the early pioneers in this field.

Since that time, the Expandi self inflatable oil containement boom has outsold all other single oil boom types worldwide. More than 800,000 meters of boom are in service today.

Expandi has also designed special equipment to further enhance the performance of the self inflatable boom, such as the Roto Pac, the Sea Sledge, the lifting slings and the Cleaning machine. This equipment has maintained the Expandi boom as the leader in its field.
