Some ready-mixed concrete producers are also becoming concrete pumpers. Before you buy a concrete pump and begin pumping concrete, be certain you can bear the costs of operating a concrete pumping business. You must be sure you have sufficient customer demand and be able to finance and maintain the required equipment. You'll also need operators who know how to operate, clean and maintain concrete pumps. Central Lakes College in Staples, Minn., has recently begun the first college-level pumping course in the United States.
