Cementos Argos Brand Guidelines: Medellín 1934, Summit Materials & Argos Materials

A Medellín company, then a family of regional cement makers.

Cementos Argos takes its name from a company founded in Medellín in 1934. English Wikipedia gives the founding date as 27 February 1934 and lists the founders as Claudino Arango Jaramillo, Rafael and Jorge Arango Carrasquilla, Carlos Sevillano Gómez, Leopoldo Arango Ceballos and Carlos Ochoa Vélez; Spanish Wikipedia, citing Valora Analitik in 2024, gives the original name as Compañía de Cementos Argos. According to English Wikipedia, the factory began production in 1936 and the company paid its first dividend in 1938.

The family tree has a twist that the company spells out on its own history page. Argos says the 1934 Compañía de Cementos Argos is today’s Grupo Argos, the Medellín holding company, while the listed cement business, Cementos Argos S.A., descends from Cementos del Caribe, founded in 1944. The Argos name and the oldest company date from 1934; the cement maker that carries the name today is the heir of a sister company set up a decade later.

That sister was one of many. English Wikipedia describes how Argos, after an association with Cementos del Nare, helped set up cement companies across western Colombia: Cementos del Valle in 1938, del Caribe in 1944, El Cairo in 1946, de Caldas in 1955, Tolcemento in 1972, Colclinker in 1974 and Cementos Rioclaro in 1982. Spanish Wikipedia adds that the Cementos del Valle plant, created with businessmen from the Valle del Cauca, began operating in 1941. In the 1990s, English Wikipedia says, Argos also bought a stake in Cementos Paz del Río.

The regional companies were brought together in 2005, when, English Wikipedia says, Argos merged all of its Colombian cement companies; the company’s own timeline counts eight. Until 2012 the holding company was called Inversiones Argos, English Wikipedia notes, citing Portafolio; it then took the Grupo Argos name, and the company’s timeline records a spin-off of non-cement assets to Grupo Argos. In May 2026 El Colombiano still described Cementos Argos as a Grupo Argos company.

Colombia, the Caribbean and the United States.

Argos first looked abroad in 1998, when, according to English and Spanish Wikipedia, it bought Corporación de Cemento Andino in Venezuela. That plant passed to the Venezuelan state in 2007; Spanish Wikipedia cites El Tiempo’s report of the expropriation order in August that year. In May 2026 El Estímulo reported that Argos had restored commercial relations in Venezuela, selling through exports and distribution rather than reinvesting in a plant there.

The Caribbean followed. Spanish Wikipedia records that in 2009 Argos bought Holcim’s holdings in Panama and the Caribbean, and that it expanded into Suriname in 2010, French Guiana in 2014 and Puerto Rico in 2015. The company’s timeline also lists the purchase of Lafarge’s assets in Honduras and the opening of a plant and a free-trade zone at Cartagena, on Colombia’s Caribbean coast. Its history page names Colombia, the Dominican Republic, Haiti, Honduras, Panama, Suriname, French Guiana, Puerto Rico and the Antilles as the places where it operates.

The United States became a second home market; English Wikipedia says it was where Argos had its largest concrete production capacity. In 2005 Argos bought Southern Star Concrete and Concrete Express, and in 2006 Ready Mixed Concrete Company, English Wikipedia says; in October 2011 it bought Lafarge’s operations in the south-eastern US, adding two cement plants, a grinding plant, 79 concrete plants and five terminals. The company’s timeline adds assets bought from Vulcan in Florida and Heidelberg’s cement plant at Martinsburg, West Virginia. English Wikipedia gives Alpharetta, Georgia, as the headquarters of those US operations.

At home the range is grey cement, ready-mixed concrete, aggregates and hydrated lime, each with its own section on the company’s site, which describes cement made from quarried limestone, clay, iron ore, sand and gypsum for concrete, mortar, rendering and finishes. English Wikipedia calls Argos the only producer of white cement in Colombia. The company has also started smaller ventures: Greco, which works with construction waste, and Caltek, a maker of quicklime and hydrated lime. In its Caribbean and Central American region it introduced Smart Pack Argos, a cement bag that, the company says, breaks down inside the concrete mix.

How cement makers present themselves.

Cement is sold in bags by the million, so the makers in this guide mostly present themselves through plain, solid wordmarks that have to read on a sack, a lorry, a silo and a dealer’s signboard. Their palettes tend towards greys, reds and greens, often with one strong colour that can be spotted across a building site. Imagery leans on the industry itself: quarries, kilns, grinding units, bulk terminals and finished buildings, more than people or lifestyle scenes.

Their websites are usually split by audience. Pages for individual home builders sit beside pages for engineers, contractors and infrastructure buyers, and products are often listed by cement type — ordinary Portland, Portland pozzolana, slag and composite cements — and by strength class or intended use, alongside ready-mix concrete and building products such as plasters, waterproofing and tile adhesives. Several makers add home-building guides, how-to videos, store locators and calculators for estimating materials.

Sustainability has become a standard section. Many cement groups publish sustainability reports and pages on lower-carbon or blended cements, alternative fuels, waste-heat recovery and water use; this guide reports such material only as the companies or dated sources state it, and makes no claims of its own about emissions or performance. Investor pages, annual reports and capacity figures in million tonnes a year sit close by, because many of these makers are listed companies that grew through acquisitions.

Community and safety programmes complete the picture, from local schools and water projects near plants to training for masons and contractors. For a design reader, the interest lies in how heavy, commodity products are given a recognisable face: a name on a bag, a colour on a truck, and a tone of voice that speaks both to a family building one house and to a highway contractor.

Summit, Quikrete and a new US platform.

The first American chapter ended in two steps. In January 2024 Argos closed a deal to combine its US operations with Summit Materials, the NYSE-listed building-materials company, after Summit’s shareholders approved it at an extraordinary meeting on 11 January 2024, the company says. That made Argos a shareholder in Summit rather than an operator under its own name; its investor pages put the stake at 31% when Summit announced an agreement to be acquired by Quikrete Holdings. Quikrete’s purchase went ahead: in November 2025 Caracol Radio reported that Cementos Argos had sold its Summit stake in that sale, and that a share buyback requested by Grupo Argos, to return part of the gains from the Summit divestment, had closed its acceptance period on 7 November 2025.

Argos has not left the United States for good. In May 2026 El Colombiano reported that Cementos Argos had begun separating its business into two platforms, Argos Latam and Argos Materials, the latter described as its aggregates platform in the United States, alongside work to expand a quarry in the Dominican Republic and build logistics toward markets such as Houston. Its board also approved funding for Argos North America Investments, the company set up to hold its US investments and operations, the paper reported. Spanish Wikipedia, citing the company’s 2024 integrated report, gives its cement production that year as 14.4 million tonnes.

The company’s own site presents it as a multinational cement and concrete group, with product sections for cement, concrete, aggregates and lime, an investor-relations area and long runs of pages on sustainability, climate change, innovation and housing programmes. In March 2024, its investor pages add, shareholders approved converting the company’s preferred shares into ordinary shares.

For a design guide, Cementos Argos shows how a 1934 name can outlast the company structure behind it, and how a regional federation of plants became one listed brand across Colombia, the Caribbean and, again, the United States. Compare Cemex, another Latin American cement group, and Votorantim Cimentos. For this guide we use a valley green, ink, pale sage and kiln ochre with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
