About Lomax
Lomax is the concrete brand of Loma Negra. The company bought the concrete operations of several producers in greater Buenos Aires and Rosario in 1998 and merged them into itself in 2010. It runs eleven Lomax concrete plants and says it leads the concrete market in those two areas, specialising in large construction projects and customised mixes; part of its aggregates come from the La Preferida quarry in Olavarría.
