Read the Case Study
Heavy chequered plate metal covers were installed over an underground interceptor at a manufacturing site in Bahrain. The interceptor was in a heavily trafficked area used mainly by HGVs and other support vehicles. The facilities manager required a replacement trench covering solution that would be capable of supporting loads of up to 40 tonnes while allowing safe, fast removal by site maintenance teams.
Innovative. Durable. Practical. Proven.
The previously installed covers were not fit for purpose as they had been loaded beyond their elastic limit and as a result suffered from permanent deformation. In addition, the covers suffered from corrosion and were beginning to break down.
The specifying engineer was familiar with Fibrelite products from a previous project and reached out to Fibrelite for help solving this issue. An aluminium frame was fitted to stabilise the covers.
Fibrelite’s GRP trench access covers can support the heavy loads required (over 40 tonnes) without permanent deformation. Fibrelite GRP manhole covers are also corrosion-resistant and lightweight, allowing for easy manual removal, delivering a maintenance free solution (fit-and-forget).
All Fibrelite trench covers can be safely removed and replaced manually by two people even at F900, using the FL7 lifting handles (at all load ratings).
Covers were manufactured and delivered to the local contractor within the tight construction schedule and provided a long-term solution for the client.
