GRP Odour Covers
Engineered, manufactured and installed for safe, compliant odour containment in corrosive environments.
Why Choose GRP Odour Covers?
GRP (Glass Reinforced Plastic) is widely used for odour containment, offering superior corrosion resistance, lightweight strength and low maintenance compared to traditional metal alternatives.
✔ Walk-on and non-walk-on options to suit project needs
✔ Custom design flexibility – tailored to any tank size, shape, or layout
✔ Reduced odour volume – flat cover design lowers air space under the lid, reducing treatment costs
✔ Corrosion-resistant – won’t rust, peel, or degrade in harsh wastewater environments
✔ Lightweight construction – easier handling, faster installation, and reduced transport costs
✔ Low maintenance – resistant to chipping, fading, and costly repairs

Frequently Asked Questions
Walk-on covers are structurally designed for pedestrian loads and maintenance access; non-walk-on covers provide containment where access on top is not required.
Yes. We design flat, pitched, curved and segmented panels to suit any geometry, with sealed joints and access points as required.
Yes. Flat cover designs reduce the headspace volume, lowering the amount of air that needs extracting and treating.
