Composite trench panels force out concrete competitors

A Florida-based water treatment facility turns to composites when it needs a corrosion-resistant, lightweight, durable alternative to its deteriorating concrete trench covers.

Fiberlite (Pawcatuck, Conn., USA) reports that a large water treatment plant on the Atlantic coast of Florida has replaced its aging, concrete trench panels with a series of Fibrelite’s lightweight, composite alternatives.

The facility, which produces approximately 30 million gal of drinking water per day, requires access to service pipe work on a regular basis for maintenance and repairs. The large concrete panels the plant had in place, common within the water treatment industry, were not only difficult and dangerous to remove but had also degraded and crumbled over time.

Though metal covers were considered as a replacement, the following benefits meant Fibrelite’s FRP composite covers were chosen:

  • Lightweight for easy and safe manual removal
  • Non-slip properties equivalent to a high-grade road
  • Chemically inert and corrosion resistant
  • Extremely strong and durable

Fibrelite's range of fiberglass access covers and modular trench panels are used in many industries including water and water treatment, ports and docks, municipalities, transport, power and energy as well as retail, commercial and industrial developments.
