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.

The Right vs. Wrong Way to Install

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.
