Construction in Rivers
Working in rivers
Working in and around water presents significant practical challenge requiring clear, outcome-focused thinking, particularly when safety and environmental protection must be front and centre in project planning.
Rivers are especially sensitive environments, where pollution from construction activities can cause immediate and lasting harm to ecosystems. Effective protection in these settings requires more than good intentions, it demands a structured, process-driven approach and a practical understanding of both the installation constraints and the performance of potential solutions that balance performance and practicability.
With decades of experience, we are a trusted partner for specialist contractors operating in flowing water environments. We pride ourselves in having a strong track record in specifying and delivering the right environmental protection measures, tailored to the complexities of each site.
Our expertise lies in balancing innovative approaches with proven techniques to achieve effective pollution control, ensuring our clients can operate responsibly, compliantly, and with confidence.

Solutions for projects involving rivers
Working with
Environmental protection during dredging and de-silting operations
Dredging and de-silting can release high volumes of sediment and contaminants into watercourses. We specify robust, low-impact protection systems designed to prevent downstream pollution and minimise disruption to aquatic habitats.
Protecting water and aquatic life from pollution
We offer proven systems and techniques to prevent suspended solids, hydrocarbons, and other pollutants from being released downstream. Our solutions balance performance and practicability are designed to minimise ecological disruption and maintain regulatory compliance and environmental compliance throughout works.
Preventing pollution during bank protection works
Activities such as regrading or strengthening riverbanks can pose pollution risks. We provide site-specific support to protect water quality and support safe working methods in riparian zones.
River realignment, headwalls, weirs and bridge works
We help mitigate risk during major interventions in river corridors, such as realignment, weir modifications, and the installation or removal of culvert headwalls and bridge structures. Our process-led approach ensures protection measures are practical, effective, and fully compliant.
Mitigating risk during pipeline protection works in rivers
Gas, water, and sewer pipelines crossing rivers demand careful planning and protection. We support these works with bespoke solutions that balance performance, simplicity and sustainability that safeguard both infrastructure and the receiving water environment.
Training and support for river-based works
We offer specialist formal and informal training to upskill teams and build environmental awareness for operatives and project teams working in river environments. Our targeted training to upskill teams and build environmental awareness focuses on regulatory compliance and environmental protection, risk mitigation, and the practical realities of working in water, helping you build capacity and confidence.
