Abstract: 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.

Abstract: An environmental control dike system constructed of a plurality of bolted steel sections supported by steel posts set in concrete below average frost depths, the interior area of the steel wall having a synthetic liner cover with mating geotextile pad, joined to the flanged top of the steel wall by a plurality of V-shaped steel clamps sized to securely form the synthetic liner and geotextile pad, compressed gently but firmly, into a 180 degree fold around the flanged top of the steel wall, the V-shaped steel clamp being held securely in place by a plurality of self drilling screws into the top flange of the steel wall.
