Traditionally installed concrete chambers and cast-iron manhole access covers posed operating difficulties:

• Covers – the traditional cast-iron manhole covers were very heavy so could not be easily removed and replaced using hand-held tools
• Chambers – the extreme weight of the concrete chambers made them difficult to install and required specialist machinery to move them, including when slight adjustments were needed

Fibrelite’s lightweight GRP composite manhole covers and tank sumps provided an easy-install solution.
Key benefits for this project:

• Lightweight Fibrelite manhole covers can be safely manually removed by one person using the FL7A ergonomically designed lifting handle and incorporate a watertight seal, preventing groundwater ingress
• Fibrelite chamber systems are also made of a lightweight GRP material allowing a simple installation, while a smooth finish ensures easy handling and excellent entry boot sealing. All Fibrelite chambers/sumps are also able to withstand high groundwater pressure and are vacuum testable during and after installation (as well as being tested before leaving the factory)
• The customer was extremely satisfied with the ease of installation
