Aegion

Aegion is the former name of an American infrastructure services company that is now known as Azuria Water Solutions. The business provides construction, maintenance, protection, rehabilitation, engineering, design, manufacturing, distribution, and related technical services for infrastructure assets. Its customers and projects span water and wastewater systems, oil and gas facilities, power generation, food manufacturing, industrial plants, and other public and private infrastructure. The company’s corporate history is rooted in Insituform Technologies, founded in 1971 and associated with cured-in-place pipe rehabilitation. This trenchless method enables operators to rehabilitate certain existing pipelines by installing and curing a liner inside the host pipe, reducing the need for conventional excavation and limiting disruption to roads, properties, and surrounding infrastructure. Over time, the business expanded beyond water and wastewater rehabilitation into energy infrastructure, industrial corrosion management, structural strengthening, and broader asset-protection services. Aegion Corporation was formed in 2011 as a parent company for Insituform and affiliated businesses. Its portfolio subsequently included specialist operations such as Corrpro, Fibrwrap, Insituform, Underground Solutions, MTC, C&L Water Solutions, Inframark, CULY, and EN-TECH Infrastructure. Together, these businesses addressed pipeline rehabilitation, protective coatings, cathodic protection, structural repair and strengthening, engineering, research and development, licensing, and infrastructure construction. In 2021, New Mountain Capital acquired Aegion in a transaction valued at $963 million, taking the company private. The business later adopted the Azuria Water Solutions name. Although the Aegion name remains important to the company’s corporate history and brand identity, the current organization is presented as Azuria and continues to focus on extending the service life, reliability, and resilience of critical infrastructure. It is primarily a business-to-business services platform rather than a consumer product brand, with value derived from specialized engineering, field execution, proprietary rehabilitation methods, and the integration of multiple infrastructure-focused operating companies.

Aegion’s history begins with Insituform Technologies, established in 1971. Insituform became associated with trenchless pipeline rehabilitation and the cured-in-place pipe process, a method for renewing certain existing pipelines without the extensive surface disruption normally associated with open excavation. The approach was particularly relevant to municipal water and wastewater networks, where replacing buried pipes can affect streets, buildings, traffic, and other utilities. As the business developed, its activities expanded across infrastructure sectors and geographies. In addition to pipeline rehabilitation, the company and its affiliates became involved in engineering, construction, manufacturing, distribution, coatings, cathodic protection, research and development, licensing, and infrastructure maintenance. Its target assets included water and wastewater pipelines, oil and gas facilities, power plants, food-manufacturing sites, industrial systems, buildings, bridges, tunnels, waterfront structures, and other critical infrastructure. Aegion Corporation was formed in 2011 as a parent company for Insituform and related businesses. The new corporate structure reflected an effort to organize a wider group of infrastructure-protection and rehabilitation operations rather than operate solely as a pipeline-lining company. The group’s family of companies included Corrpro, Fibrwrap, Insituform, Underground Solutions, MTC, C&L Water Solutions, Inframark, CULY, and EN-TECH Infrastructure, among others. Their combined capabilities covered corrosion management, protective systems, structural strengthening, utility infrastructure, pipeline rehabilitation, and associated engineering and construction work. Aegion’s business model centered on helping asset owners preserve existing infrastructure and extend useful operating life. Its services could be applied to underground piping, industrial equipment, energy facilities, and civil structures. This positioned the company between specialist engineering and construction services: it supplied technical solutions and project execution rather than standardized consumer goods. In 2021, New Mountain Capital acquired Aegion in a $963 million transaction. The acquisition removed the company from the public markets and converted it into a privately held business. The organization subsequently became known as Azuria Water Solutions. Under the Azuria identity, the business continues the infrastructure-oriented activities associated with Aegion, particularly water and wastewater systems, pipeline rehabilitation, corrosion protection, structural rehabilitation, and related engineering and construction services.

  Corrosion control and cathodic protection

  Corrosion-control services address deterioration affecting pipelines, tanks, industrial equipment, and other metallic infrastructure. Offerings include corrosion engineering, protective coatings, monitoring, and cathodic protection systems intended to reduce corrosion-related damage and help asset owners manage inspection, maintenance, safety, and reliability requirements.

• Structural infrastructure services

  Structural strengthening and repair

  Structural services protect and rehabilitate buildings, bridges, tunnels, waterfront structures, and other civil assets. The work can include engineering, repair, strengthening, and protective systems designed to restore structural performance or extend the operating life of existing infrastructure without requiring complete replacement.

• Utility infrastructure services

  Water and wastewater infrastructure services

  Water and wastewater activities cover the rehabilitation, maintenance, engineering, and protection of buried and above-ground utility assets. These services support municipal and other infrastructure owners seeking to improve reliability and defer disruptive replacement projects through targeted renewal and asset-management programs.
