​Owned and operated since 1979, CTI was founded with just one truck and transfer unit. We have since grown our division of transfer trucks into a dedicated CARB compliant fleet. With the benefit of company trucks, we are able to meet your material needs where you need it, when you need it. Serving all of Riverside, Orange, Los Angeles, San Diego, San Bernardino, and surrounding counties, we will be sure to follow you wherever your next project may be. Our transfer service offers deliveries of sand, gravel, decorative landscape materials. No job is too big or too small!
