Case Studies

Baffle wall installation

This project involved the fabrication and installation of 360 metres of baffle curtain, securely mounted using high-grade stainless steel brackets and fixings to ensure long-term durability and corrosion resistance.

The baffle curtain structures form an integral component of the asset’s infrastructure. Designed to regulate and direct water movement within the reservoir, they facilitate controlled flow patterns, helping to maintain a consistent and continuous water circulation system. This controlled flow improves operational efficiency and supports the overall performance and longevity of the reservoir system.

The installation was completed to exacting standards, ensuring structural integrity, reliability, and alignment with the asset’s hydraulic requirements.

HDPE External Membrane Installation – 3 Metre Trench Detail

We completed the installation of a high-performance HDPE membrane system to the external structure of a Victorian-era service reservoir.

The works included the external roof structure lining and the formation of a 3-metre deep trench detail designed to protect the perimeter walls from long-term exposure to the elements and ground ingress.

Operating within a live programme environment, the team worked through challenging site conditions to deliver the installation within the agreed timeframe. Early completion supported the client in progressing the asset toward recommissioning, increasing operational capacity within the region.

A well-executed containment and protection solution, delivered safely and efficiently.

Cookham Dean Service Reservoir

Project Overview:
At Cookham Dean, we were tasked with restoring a Victorian-era distribution service reservoir — a remarkable piece of 19th-century engineering still serving as part of the local water infrastructure. Over the decades, natural aging and material wear had led to multiple ingress issues, threatening both water quality and structural integrity.

Challenges:

• Significant water ingress due to the age and porosity of original Victorian construction materials
• Risk of contamination and water loss impacting distribution efficiency
• Requirement to preserve the historic nature of the structure while meeting modern water safety standards

Our Solution:
Through careful assessment and innovative repair methods, our team successfully rejuvenated this historic reservoir. A Flagon membrane system was installed, providing a robust waterproof barrier to:

• Eliminate water ingress and loss
• Safeguard against contamination
• Extend the operational life of the reservoir

Outcome:
The project was completed efficiently and with minimal disruption. The client was extremely pleased with the results — a rejuvenated, fully functional Victorian reservoir now equipped to continue serving the community for years to come.
A proud moment: Breathing new life into a piece of British engineering heritage while ensuring it meets today’s standards of performance and reliability.
