Heavy Cast Iron Replaced by Fibrelite’s Lightweight Composite Covers

Read the Case Study

A wide range of Fibrelite covers have been specified for a sewage treatment works following plans for a refurbishment and modernisation of the site. What’s more, this well-known water company were looking to combat the increasing problems with metal theft and the health and safety issues associated with the existing heavy and corroding cast iron covers.

With resin transfer moulded (RTM) composite having zero resale value to the scrap market, being lightweight for easy removal and easily achieving D400 load ratings where required, Fibrelite ticked all the boxes.

29 covers were specified in total:

2no. 1400 x 700mm
4no. 450 x 800mm
2no. 600 x 600mm
12no. 900 x 900mm
3no. 760 x 760mm
6no. 450 x 450mm

These Fibrelite covers are currently being installed. Rather than excavate, the covers will be sat directly on top of the manholes with a new layer of concrete shuttered on top of the existing up-stand.

Easy and Safe Access

Once installed, Fibrelite’s composite access covers are lightweight, durable and very strong.

Every Fibrelite cover is manufactured using high-technology RTM production methods to create a highly engineered, monolithic composite product.

Innovative. Durable. Practical. Proven.

Cost Competitive – Whole Life Cost

Composite covers have always been seen as a high-cost alternative to traditional metal products. However, with Fibrelite’s technological advances in the manufacturing process, the development of our B125 covers and rising metal prices, composite can now compete head to head with the likes of cast iron.
