The 6.5 cubic yard concrete washout is an environmentally friendly concrete wash out box that is specially designed to be watertight and has built-in ramps to allow pump trucks and ready-mix trucks to back up onto the container. It will enable enough clearance so the trucks can quickly clean out any remaining concrete into the container. The washout box can handle up to 6.5 cubic yards or nearly 1100 gallons of capacity. It equates to handling washout from approximately 350 yards of poured material or containment for approximately 35 ready-mix trucks and two pump trucks.
