As Castellano became more powerful in the Gambino family, he started to make large amounts of money from construction concrete. Castellano's son Philip was the president of Scara-Mix Concrete Corporation, which exercised a near monopoly on Staten Island on construction concrete. Castellano also handled the Gambino interests in the "Concrete Club," a club of contractors selected by The Commission to handle contracts between $2 million and $15 million. In return, the contractors gave a two percent kickback of the contract value to The Commission. Castellano also supervised Gambino control of Teamsters Union Local Chapter 282, which provided workers to pour concrete at all major building projects in New York and Long Island.
