A modular secondary containment unit that can be adapted to surround an above-ground fluid storage tank and can include a plurality of corner assemblies is described herein. Two or more components of each of the corner assemblies can be composed of one or more reinforced resin composite materials. The modular secondary containment units and the above-ground fluid storage tanks can be used in oil and gas exploration and production operations. An assembly for a modular secondary containment unit can include a track segment including first and second channels, a wall segment mounted on the track segment and extending within the first channel of the track segment, and a brace engaged with the wall segment and extending within the second channel of the track segment. A method of constructing a modular secondary containment unit is also provided.
