4' x 4' x 14" (Capacity 0.68 cu. yds. / 140 US Gallons). Our Corrugated Washout is portable, easy to setup, and cost effective. It is made from heavy-duty, 350# VC3 water-treated Kraft fiberboard so that it is light and durable yet folds flat for easy transportation and storage. The heavy-duty, water-treated, Kraft fiberboard that our corrugated washout is made from is durable enough to be left outside in the elements for the duration of short- to medium-term projects. If rain is expected, the poly bag can be tied closed so the washout material wonﾐt take on additional water and extend the evaporation time. It is designed to be a portable, EPA-friendly solution for containment of hazardous construction site washout material such as: concrete sediment, paint, drywall mud, stucco, and mortar.
