Abstract: The disclosed technology is generally directed to a tile-and-frame assembly installable in concrete that includes a modular frame and a top panel. The frame includes four corner supports and side supports. Each corner support includes: a side wall, a second side wall, a brace, and an anchor. Each side support includes: a side wall, a brace, and an anchor. At least four side supports are situated along a perimeter of the frame such that the four corner supports and the side supports situated along the perimeter of the frame define the perimeter of the frame, and such that the frame size is modular based on a cardinality of the side supports situated along the frame perimeter. The top panel is coupled to the frame. The top panel includes at least one tactile feature.

Abstract: The containment device constructed according to a preferred embodiment of the invention includes a rectangular base formed of an impermeable material, a deformable wall formed along a first set of opposable ends of the rectangular base, and a support wall formed along at least a portion of a second set of opposable ends of the rectangular base. The deformable wall has an upright configuration in which the deformable wall is capable of containing hazardous materials within the containment device, and a deformed configuration enabling wheeled vehicles to pass over the deformable wall to enter and exit the containment device. The support wall includes rigid upright support members maintaining the support wall in an upright position and, preferably, additional rigid hypotenuse and base members that coact with the upright support members to form right triangles anchored to a skirt affixed to the base of the support wall.
