An anti-settlement manhole cover, also known as a self-leveling manhole cover, is an advanced type of road access cover designed to reduce the common problems caused by traditional fixed-frame manhole systems.
Unlike conventional manhole covers, the self-leveling structure allows the cover frame to better adapt to road movement and traffic pressure, helping prevent:
This makes self-leveling manhole covers an ideal choice for busy roads, highways, urban streets, and areas with heavy traffic loads.
The biggest advantage of an anti-settlement manhole cover is its ability to reduce sinking problems.
Traditional manhole covers are fixed directly into the pavement structure. Over time, repeated vehicle pressure and road movement can cause the surrounding area to settle.
The self-leveling design helps maintain the correct position between the manhole cover and road surface, improving long-term road performance.
Manufactured from high-strength ductile iron, our heavy duty manhole covers provide excellent mechanical strength and impact resistance.
They are suitable for:
Different load classes are available according to project requirements, including EN124 standards such as B125, C250, and D400.
Uneven manhole covers can create noise, vibration, and uncomfortable driving conditions.
The self-leveling manhole cover system helps keep the road surface flat, reducing:
It provides a smoother and safer driving experience.
