Ambienta No Dig Alliance Acquires Altiva in Underground Infrastructure

Ambienta, a leading European private equity firm focused on sustainability-driven investments, announces that its platform company, No Dig Alliance, has acquired Altiva, a Norwegian specialist in underground pipe rehabilitation and manhole renovation. The deal, announced on April 9, 2026, represents No Dig Alliance’s first expansion into the Norwegian market and its second add-on acquisition in a short period.

While financial terms of the transaction remain undisclosed, the acquisition strategically positions No Dig Alliance to capitalize on the estimated €3 billion underground infrastructure market, which is experiencing rapid growth driven by increasing demand for sustainable and minimally invasive maintenance solutions.

No Dig Alliance operates in the underground infrastructure services sector, providing trenchless technology solutions that enable pipeline rehabilitation and maintenance without extensive excavation. Altiva complements this offering with specialized expertise in no-dig pipe rehabilitation and manhole renovation, enhancing the platform’s technical capabilities and service portfolio.

Ambienta, founded in 2007, is a private equity firm that invests in companies promoting environmental sustainability across Europe. Its platform strategy involves building market-leading businesses in environmental services and infrastructure sectors. Altiva, based in Norway, is recognized for its advanced trenchless technology solutions that reduce environmental disruption and improve infrastructure longevity.

According to Ambienta, the acquisition will enable cross-selling of Altiva’s no-dig solutions to Ambienta’s existing environmental and infrastructure clients, expanding service offerings to new customer segments. Operational synergies are expected through consolidation of administrative functions and economies of scale in procurement. Additionally, integrating Altiva’s expertise will streamline project management and enhance the platform’s sustainability credentials.

Industry trends show growing demand for trenchless technologies as municipalities and utilities seek cost-effective, eco-friendly infrastructure maintenance methods. The combined entity is expected to strengthen its market position in the niche no-dig pipeline rehabilitation sector, accelerating industry consolidation and increasing competitive pressure.

Financial details such as deal value, multiples, and funding sources have not been disclosed. No advisors have been publicly named for the transaction. Ambienta plans to integrate Altiva’s operations with No Dig Alliance’s existing infrastructure platform, focusing on retaining key technical talent and aligning corporate cultures.

Looking ahead, Ambienta aims to leverage its sustainability-driven investment approach to scale Altiva’s technology across its broader client base, driving innovation in no-dig infrastructure solutions. The acquisition underscores Ambienta’s commitment to expanding its footprint in environmental services and infrastructure markets through strategic add-ons.
