Our Company History

Ralph Hayes and Son Inc. was established in 1946, family owned and operated for the last 73 years and counting. The company began with the great grandfather Ralph and son Derrel “Bud” Hayes operating a small fertilizer and dairy cleaning business. One of the first jobs done by Ralph Hayes and Son Inc. was custom spreading of 1,000 yards of manure to Gallo farms in Modesto, California.

Bud played a vital part in the expansion of the company. With Bud’s help, the small fertilizer business turned into a large trucking company reaching far north into Napa wine country, south into the Fresno valley, west along the coast from Carmel up close of Oregon’s border and east the Sierra mountains. Sugar beet lime was processed in the nearby Holly Sugar plant providing the company with a surplus of lime for nearby farmers.

Ralph Hayes & Son began processing gypsum from allied chemical beginning in 1973 through 1993. From the early days Ralph Hayes cleaned over 60 poultry houses annually throughout the Central Valley. Bud’s sons Derrel “Buddy” and Eric both followed the family tradition after school.

With help from their father and grandfather the boys were able to continue expanding the company and their services. Buddy works with farmer and dealer relations, along with product development and dispatch of trucks. Eric took on the job of general management, operations and fleet management.

Around 1994 Ralph Hayes & Son pioneered the process of recycled wallboard gypsum, this process has come a long way since the beginning providing now a superior product and alternative to other forms of gypsum. The company also began processing mined gypsum from Baja Mexico in 2010. Over 43 years of experience in the processing and application of gypsum in the state of California we set the standard for gypsum in the state of California.

We stand behind our experience and work ethic in providing a superior gypsum product.
