Colaska is a vertically integrated company that produces almost all of its own construction materials. These include aggregates, emulsions, asphalt mixes and concrete. It also imports its own cement and asphalt oil, thus securing supply chains, improving operational performance and minimizing environmental impacts. Additionally, Colaska is a leader in recycling construction materials. This reduces waste, saves energy and contributes to everyday environmental awareness.
