Chamber Covers

Looking for durable, lightweight and corrosion-resistant chamber covers for your water or wastewater site? Our covers are made from low carbon d² Glass Reinforced Polymer (GRP), offering superior performance to steel in harsh, wet and chemically aggressive environments.

Why Choose d² GRP Chamber Covers?

Our GRP chamber covers are designed to replace traditional steel or concrete covers with minimal disruption. Custom sizes, anti-slip finishes, and load ratings are available to suit all chamber types and operational requirements.

1. Corrosion-Free Performance in Aggressive Environments

Steel chamber covers can deteriorate rapidly in the presence of hydrogen sulphide (H₂S) and other corrosive compounds common in wastewater settings.
Our d² GRP covers are inherently non-corrosive, making them ideal for long-term use in harsh chemical and H₂S-rich environments. This extends service life, reduces maintenance costs, and improves safety for operational teams.

2. Lightweight, High Strength, and Easy to Install

Thanks to our advanced composite design, d² chamber covers are up to 33% lighter than traditional alternatives — meaning they can be lifted and positioned safely without the need for mechanical handling equipment.
Despite their reduced weight, they deliver exceptional strength and load-bearing capacity, supporting safer and more efficient maintenance access.

3. Non-Conductive for Enhanced Worker Safety

Unlike steel, our GRP covers are non-conductive, significantly reducing the risk of electric shock and improving on-site safety for maintenance crews.

4. Ultra-Low Embodied Carbon – Verified with EPDs

Our d² range offers the lowest embodied carbon of any GRP cover system on the market.
With verified Environmental Product Declarations (EPDs) and closed-loop recyclability, our chamber covers help water companies meet Net Zero targets while simplifying Scope 3 carbon reporting.

Reduce Carbon, Cut Maintenance & Improve Safety — All in One Cover

If you’re looking to replace ageing, rusting steel chamber covers with a low-carbon, high-performance alternative, d² GRP Chamber Covers from Dura Composites are the ideal solution.

Our team can help you select the right cover system to meet your operational needs, compliance requirements and sustainability objectives.
