CRH Ventures’ Accelerator for Water Solutions

In 2023, CRH’s venture capital unit, CRH Ventures, launched a Water Solutions accelerator programme to help address water management challenges. The programme paired innovative startups with CRH operating companies to pilot their solutions, giving them access to 50+ years of technical expertise. A shortlist of 30 projects – spanning areas such as biofilitration, erosion control and flood detection – has now been refined to a final six, each excelling in helping to address vital components within the water ecosystem.

Supporting sustainable development

Oldcastle Infrastructure, part of our Americas Division in the US, designed a site specific StormCapture® detention solution for a customer in Lewisville, Texas. The solution required a detention system that would effectively capture and manage urban stormwater, thereby reducing flooding, erosion and sewer overflows.

Supporting the Better Management of Water Flows

CRH’s permeable pavement solutions provide effective protection against flooding and soil drying out. Stradus, in CRH’s Europe Division, repaved Park Piot in Turnhout, Belgium, to create a green space that addressed local water problems by allowing water to permeate into the ground as much as possible. This project was nominated for the Febe Elements Awards in the category ‘Precast in Landscape’. In addition to managing water challenges, the design created an attractive urban area that combines active, quiet, and educational zones.

Managing Water Resources Efficiently

The Rogue Valley International-Medford Airport in Oregon, U.S. faced stormwater management challenges, including the need to comply with environmental regulation, treat pollutants, and site footprint limitations. Oldcastle Infrastructure, in CRH’s Americas Division, provided a Boxless BioPod™ system that uses horizontal layers of mulch, proprietary media, and aggregate, with an underdrain. The low impact development achieved optimal treatment of stormwater and sediment retention at a high flowrate, meeting all regulatory and client requirements.

Safeguarding the Quality of Water

CRH's solutions are helping to safeguard water quality by preventing potential pollutants from entering rivers, lakes, and oceans. Hydro International, in CRH's America's Division, operates in countries including the United Kingdom (UK) where they helped to improve the ecological status of Beverley Brook, upstream of the River Thames in London. A Downstream Defender® system was installed to remove significant amounts of trash, oils, sediments, and heavy metals. Hydro-Logic® Smart Monitoring was also implemented to help identify when maintenance is needed.

Managing Water Utilising Nature-Based Solutions

CRH seeks opportunities to use nature-based solutions for water management, with the additional benefits of habitat enhancement. Dufferin Aggregates, in CRH’s Americas Division, is supporting the community in Paris, Ontario, Canada, through a nature-based solution that lowers elevated nitrate levels in groundwater from nearby agricultural activity. It also provides important habitat for amphibians, turtles, and birds. Ponds created on its site have been planted with native wetland plants to reduce nitrates, helping the town to keep drinking water quality within provincial levels.


Our Targets and Progress


100% of our operating companies to have Water Management plans in place

We are continuing to take action to conserve and use water resources responsibly in our own operations. Our flood management and stormwater solutions are helping to protect vulnerable communities and allow them to adapt to increasingly volatile weather patterns. Our solutions are also providing innovative, reliable infrastructure to assist in effective water management, protect groundwater sources, providing access to clean water resources and treatment of wastewater.

We are innovating and enhancing the range of solutions we offer to support water resiliency. Through our venturing unit, CRH Ventures, in 2023, we launched an accelerator programme for Water Solutions that has enabled us to identify and work with key of innovative technologies that address water challenges.

We are on track to achieve our target:

  • 89% of our operating companies had Water Management Plans in place in 2023
