A family-owned business since its launch, Robertson’s Ready Mix opened its Riverside, Calif., doors in 1969. Forty-four years later, the company has grown to operate more than 40 ready-mix plants and 12 aggregates facilities across seven counties in Southern California.

Even with all that has changed over the years, Robertson’s maintains its original vision, striving to offer competitive prices and develop close customer relationships. The producer has taken part in everything from home improvement construction to municipal projects.

Mark Raigosa, quality control, cites high-profile examples of Robertson’s work, including the Alameda Corridor railroad project, a 20-mile rail “expressway” from Alameda Street in Long Beach to downtown Los Angeles. The corridor is one of the region’s largest transportation projects in recent years. Other projects include the Gerald Desmond Bridge renovation in Long Beach, and a courthouse restoration in San Bernardino.

Robertson’s has also been deeply involved in the pervious concrete movement. In 2008, the producer began hosting the NRMCA’s pervious certification classes for contractors, providing its parking lot as a working space for contractors to place concrete.

But the producer’s objectives go beyond the plant: Robertson’s is committed to educating future members of the concrete industry. Raigosa works with engineering students at Cal Poly Pomona, mentoring them for the American Society of Civil Engineers’ National Concrete Canoe Competition.

“[They learn] how to work with lightweight concrete, what’s involved in producing it, and how different aggregates can be used to create different properties,” Raigosa says. “It’s a hands-on look at how it’s done.”

And that hands-on approach has paid off: In 2013, Cal Poly Pomona won the Pacific Southwest Conference canoe race, and ultimately placed 13th in the national competition.
