Fibrelite custom design and manufacture retrofit replacement for heavy concrete trench access covers
Fibrelite were contacted by a third-party construction company whose client had tasked them with obtaining a lightweight upgrade for their traditional heavy concrete infill trench covers. It was essential for the new trench covering arrangement to be retrofitted into the existing frames, lightweight and easy to use with no specialist training or equipment required for operation.

Key Requirements
This client required frequent access to services within these trenches, located on the bridge and grass banking on the site. It soon became apparent that the previously installed concrete infill access covers posed a problem in this regard – costing additional time and money due to specialist equipment and trained personnel being required every time access was required:
- Specialist training required for operatives.
- Heavy duty lifting apparatus had to be procured from a third-party hire company in each instance when access was required.
- The sheer weight of the concrete covers posed health and safety risks, even when operatives were appropriately trained.
- Replacement trench covering solution must include a restraining bolt feature.
In order to prove cost-effective, it was essential that any replacement offering had be retrofitted to the existing trough rebate. C250 and A15 load rated trench covers were required for trafficked and non-trafficked areas.
The Fibrelite Solution
Fibrelite supplied a custom engineered trench covering arrangement to the client which would satisfy all specifications as detailed from the outset. Thanks to effective discussion between all three parties, Fibrelite’s proposal was accepted thereafter.
- Custom trench access covers and frame section manufactured and supplied to fit directly into the existing concrete trough rebate.
- Fibrelite lightweight GRP trench access covers manufactured with restraining bolt down feature.
- Bespoke C250 and A15 load rated covers supplied in line with client requirements: C250 for bridge area which would be trafficked and A15 for the steep sloped banking which would see only pedestrian foot traffic, but would require single cover removal without remaining cover displacement
- The new Fibrelite trench access covers can be easily and safely removed and replaced manually by two people using the ergonomically designed Fibrelite FL7 lifting handles.
