A tripling or more in the production rate of precast concrete building units utilizing reusable mold forms is achieved by casting the units vertically on a wheeled base between separable vertical mold forms. The partially cured poured concrete unit is horizontally transported on the wheeled base from between the separated molds to complete the curing independently thereof, the forms being immediately serviceable with another wheeled base for molding another unit.
