Testing and Quality Control
Ensuring zero-failure performance and global compliance through rigorous BS EN 124 testing protocols.
Load Capacity & Permanent Set Testing
Structural integrity is our absolute priority. Every Fibera FRP cover undergoes rigorous point-load capacity and permanent set testing, strictly adhering to the BS EN 124:2015 European standard. To simulate decades of real-world highway traffic, we subject our covers to advanced multiple-load cycling. This exhaustive testing process guarantees zero structural compromise and prevents permanent deformation under extreme vehicular stress.
Raw Material Purity & Batch Validation
The ultimate strength of an FRP composite lies in its underlying chemistry. We maintain strict, climate-controlled storage environments to protect our raw components from humidity, moisture, and particulate contamination. Before entering the production line, our in-house laboratory conducts comprehensive batch testing on all resins and fiberglass reinforcements, ensuring they perfectly match our exacting mechanical specifications.
Standard Installation Guidelines
Proper installation is critical for long-term performance. Follow these mandatory steps for frame bedding and haunching to ensure your Fibera FRP covers maintain maximum structural integrity.

- Ensure that you are using the right load capacity cover and frame based on vehicle/pedestrian movement. Please follow our load selection guide.
- Do not drop or throw FIBERA cover or frame while placing it on the floor.
- Avoid impact of sharp and/or heavy objects on the cover and frame.
- Do not burn objects on or near the manhole cover, grating and frame.
- Use only supplied covers with appropriate FIBERA FRP frames.
- Use only FIBERA lifting key supplied with the FRP cover/grating to lift it.
- Occasionally remove the cover from the frame and clean the rim of the
frame of any dirt/dust/pebbles. - Do not leave the frame open without placing a cover or grating.

Installation Steps:
Installation Steps:
Prepare Bedding
Prepare the concrete bed after considering the height of the Fibera FRP frame.
Concrete Grade
The Fibera FRP frame should be completely embedded in a minimum of M-20 grade concrete.
Clear Opening
Ensure that the manhole clear opening is equal or less than the opening of the Fibera FRP frame.
Frame resting should not be hanging without ground support.
Zero-Zero Leveling
Frame should be leveled using a spirit leveler and confirming that the air bubble in
the leveler remains exactly at the center (Zero-Zero Level)
Eliminate Gaps
Check gaps under the Fibera FRP Frame. Ensure that there are no visible gaps under the frame and smooth bedding material with a trowel both inside and outside of the chamber.
Final Enveloping
Use the remaining mortar to envelope the Fibera FRP Frame paying particular attention to the corner
areas. Smooth out the mortar with a trowel to ensure good bonding with the frame and to avoid any
initial cracks in the bedding material.

Visual Guide –
The Right vs. Wrong Way to Install
✅️ The Correct Method
(Flush & Supported)
The concrete bed is level, and the entire base of the FRP frame is resting solidly on the M-20 concrete. The top of the cover sits completely flush with the surrounding road/pedestrian surface.
❌ Wrong Method 1 (Unsupported Overhang)
The concrete bed is too wide, causing the inner lip of the FRP frame to hang over the manhole opening with zero support underneath. This will cause the frame to crack under heavy traffic loads.
❌ Wrong Method 2
(Uneven / Raised Frame)
The concrete bed is uneven or missing entirely under one side of the frame, causing the frame to sit at an angle or protrude above the road surface. This creates a tripping hazard and subjects the cover to severe impact damage from passing vehicle tires.
