A granular material storage capacity increasing device and system includes a housing including a first and second side walls each having an upper edge. A roof structure is attached to and extends between the first and second side walls. The roof structure includes roof trusses each having an inner chord. A plurality of curtain assemblies is attached to the roof structure to define an auxiliary storage capacity. At least one of the curtain assemblies is mounted adjacent to and associated with the first side wall and at least one of the curtain assemblies is mounted adjacent to and associated with the second side wall. Each of the curtain assemblies a flexible panel extending between and is attached to two inner chords. A top edge attached to the inner chords and bottom edge attached to one of the first or second side walls.

Granular material storage capacity increasing device and system

A zero ground disturbance dike apparatus and method for the secondary containment of harmful chemicals that are stored in primary storage vessels, wherein the dike apparatus does not require the drilling of postholes or the setting of support posts in concrete. Sections of dike walls are attached to bracing assemblies, each bracing assembly being comprised of a brace and a base plate. Braces are configured to support the assembled wall sections and to provide resistance against the outwardly force exerted by material that is released from the primary storage vessel. Base plates attached to the braces assist in resisting bending moments that may be created about the base of the dike apparatus. The brace assembly also preferably includes at least one base support channel for additional base plate stiffness and support cables to further resist the outwardly forces exerted against the dike apparatus by said released materials.
