An internal aircell inside a first flexible structural cover of a structural air-beam used in air supported supports such as tents is connected to the internal aircell of an adjacent air-beam by means of an air-beam aircell communicating airflow port assembly attached between said aircells through a cooperating structural cover port aperture in the structural cover. The airflow port assembly allows communicating airflow between the connected aircells forming an integral air volume for inflation and deflation through a single inflation point.

A plurality of closable and removable containment berm wall supports are preferably each made from three flexible coated fabric layers and preferably each wall support incorporates three reinforcing members and incorporates a closure means that selectively can close the support into a closed triangular frame. Each berm wall support is designed to cooperate with a sleeve attached to a flexible sidewall of a containment berm unit and when the wall support is in a closed condition to hold the sidewall in an erected condition and when the wall support is in an open condition to allow the sidewall to assume a let down condition. The let down condition allows a wheeled vehicle or other object to conveniently transit over the wall for placement on a floor of the containment berm unit within the perimeter established by the sidewall.
