  • Manholes as we know them today have been in use since the mid-19th century but have evolved over time for increased safety and functionality. While they were originally built with bricks, manholes are most often built using concrete today, though some are made of plastic, fiberglass or a similar composite. Composite liners are more likely to be used in regions with a high risk of corrosion or in areas where exfiltration or infiltration into the line is common. Many manholes today are built aboveground first. These are typically referred to as precast manholes—designed to fit a dug-out space and assembled on site before being lowered into the ground.

  • Furthermore, grating can play a vital role in extending the lifespan of roads. The repeated pressure from vehicles can cause wear and tear over time, leading to cracks and potholes. By providing a textured surface, grating helps to distribute this pressure more evenly, mitigating the formation of these structural flaws. Consequently, not only does grating improve immediate driving conditions, but it also reduces long-term maintenance costs for municipalities.
