The item below is called a modular spill containment platform (from Grainger Industrial Supply, $80.55). Above, two are linked together with an included connecting strip. These platforms are designed to hold the weight of 55 gallon drums and collect any leaking fluid (actually, each can support up to 2000 lbs, according to Grainger). They also happen to be ideal for supporting heavy ice sculptures and collecting their meltwater. Each platform will hold 12 gallons of water, which is often plenty for a 4 to 6 hour event.

    The trays can be linked together on any side, so creating a very large tray isn’t a problem. Each tray measures 26 inches by 26 inches and is 6.5 inches high. So the tray below measures 52” by 52” and the connecting strips prevent water from leaking down between the trays. A small piece of plastic should go over the hole in the middle, however.

    Other sized platforms are available from Grainger as well. Dean Carlson gets credit for sharing this idea, as I first saw them at one of his shops. Dean made the trays less conspicuous by painting the yellow plastic black. These trays represent a reliable and affordable solution for a sometimes challenging problem.
