Fibrelite’s extensive range of composite trench covers can withstand the same heavy loads as traditional materials, at a fraction of the weight; while the load-carrying capacity of precast concrete trenches are derived from their structural qualities and don’t rely on the strength/quality of surrounding backfill materials.

Fibrelite covers weigh a fraction of concrete or metal alternatives and offer load ratings up to F900. This means all trench covers can be safely manually removed by two people, no matter what the load rating.

Our highly engineered composite covers are inert, very durable and capable of withstanding traffic and harsh field conditions for many years, while precast concrete trenches protect against adverse weather conditions and resist the majority of corrosive substances, providing long-term protection for underground utilities.

Fibrelite trench covers are a high-performance product created via resin transfer moulding (RTM) to create a durable, monolithic cover that will stand up to corrosion and extreme temperatures (including freeze-thaw); while the strength of precast concrete gradually increases over time. In fact, studies have shown that precast concrete products can provide a service life of over 100 years.
