CRH plc
CRH plc is the Irish-headquartered, NYSE-listed building-materials group that has quietly become a water investor. Through its corporate venture arm CRH Ventures and its Oldcastle Infrastructure business, it backs smart-water and leak-detection technology. As of June 2026 it has led 2 water venture deals and agreed a $700 million water-treatment acquisition.

The take
CRH plc is one of the largest building-materials companies on earth, an 80,000-person, NYSE-listed group that makes the concrete pipes, vaults and drainage moving water under American streets. What makes CRH worth a water investor's attention is the next step it has taken: CRH now buys and backs the technology that watches the pipes it already makes.
CRH Ventures is the clearest expression of this, the group's $250 million corporate venture arm (a CVC, meaning a fund a big company runs to invest in startups rather than an independent venture firm). Water is one of its four declared themes, and so far CRH Ventures has led two water rounds: a Series A in VODA.ai, a Boston platform that uses AI to predict which buried pipes will fail next, and a Series B in FIDO, a UK leak-detection company. Both feed CRH's own Oldcastle Infrastructure business, which sells smart-water hardware to US utilities. CRH invests where it can also sell.
CRH's bigger move is not venture at all. In April 2026 CRH agreed to acquire Axius Water, a North American water-quality and nutrient-removal platform, for $700 million, with the deal expected to close in the second quarter of 2026. Read alongside the September 2025 arrival of former Xylem chief executive Patrick Decker on CRH's board, the direction is hard to miss: CRH is treating water as core infrastructure to own, not a side bet.
CRH, for a newcomer, is best framed simply: it is not a water fund, and it will never hand you a clean water-only thesis. CRH is a strategic giant using a venture cheque book to scout the smart-water technologies that plug into a network it already owns. As of June 2026 that adds up to two water companies across two venture deals, plus one large pending acquisition, with a building-materials balance sheet behind it rather than a fund vintage.

Frequently asked
- What does CRH plc invest in?
- CRH plc invests mostly in its core building-materials business, but it has built a clear water strand. Through CRH Ventures it backs smart-water and leak-detection startups such as VODA.ai and FIDO, and through acquisitions like Axius Water it buys water-treatment platforms outright.
- Is CRH plc a water company?
- CRH plc is not a water company. It is one of the world's largest building-materials groups, listed on the New York Stock Exchange. Water is a fast-growing part of its business, served by its Oldcastle Infrastructure arm and, once it closes, the $700 million Axius Water acquisition agreed in April 2026.
- Who runs CRH Ventures?
- CRH Ventures, the $250 million corporate venture arm of CRH plc, is led by Murari Perumalsamy as Head of Ventures. He succeeded Eduardo Gomez Mendoza, who founded the unit in 2022 and now serves as EVP of Strategy for CRH Americas. Water is one of its four investment themes.
- What is Axius Water and how is it linked to CRH?
- Axius Water is a North American water-quality and nutrient-removal platform that CRH plc agreed to acquire for $700 million in April 2026, with closing expected in the second quarter. It is separate from CRH Ventures, the group's startup-investing arm, and Oldcastle Infrastructure, its water-products business.
- Where is CRH plc based?
- CRH plc is headquartered in Dublin, Ireland, and has been primarily listed on the New York Stock Exchange since 2023. The roughly 80,000-person group operates across nearly 30 countries, and its North American water business, Oldcastle Infrastructure, leads its push into smart-water technology.
