The creation of manhole cover starts from gathering its raw materials to be used. It could be made out of a an iron, concrete, or a combination of both, manhole cover design should carefully considers the standard dimensions and purpose.
(vi) Installation of the Cover: Once the desired height of the manhole is reached, a cover or top section is installed. This cover is usually made of cast iron or concrete and is designed to support the weight of vehicles or pedestrians passing over it.
Moreover, waterproof manhole covers enhance public safety. Unprotected manholes can become hazardous during heavy rains when water accumulates in streets and roadways, potentially obscuring open manholes. This can lead to accidents and injuries for pedestrians and vehicles alike. A waterproof seal reduces the likelihood of water pooling around manhole covers, thereby improving visibility and safety for all road users.
