OUR HISTORY

The Lubanko family has a long and storied history in the aggregate mining industry. Beginning with Milo Lubanko and his company, Lubanko & Sons, the family has been involved in the crushing business for over half a century. In the 1950s, Milo purchased a quarry in the Salton Sea area of Southern California to provide aggregates, asphalt, and concrete for the rapidly developing Mojave Valley. After Milo's passing, his son, Donald Lubanko, formed Diversified Materials in the 1980s and 90s, which dominated the portable crushing market in Southern California. In 1984, he moved into the Nuway Landfill to mine sand and cobble for the Industrial Asphalt Company and Owl Rock, but when those reserves were depleted, he refocused on portable crushing services. He ran the company until 1995 when he sold it. In 2014, Milan Lubanko, Milo’s grandson, founded L&G Portable Crushing & Materials, carrying on the family tradition.
