Manholes are installed to make it easier to exploit and maintain sanitation works. This means that building owners should welcome public employees into their facility who will be trying to access utilities below the ground. While visits are rare, they ensure the safety of everyone. Manholes can be made of various materials including plastic, concrete, and brick. Read on to understand how these materials make manholes different:
Ease in Installation
Manholes made of plastic are easy to install. They do not require the use of heavy machinery to transport them. In fact, they do not necessitate the presence of many workers which means a decrease in the labor cost compared to concrete manholes. Concrete manholes; however, require the use of heavy machinery.

Ability to Deal with Soil Movement
The use of brick and concrete manholes can cause soil movement or vibration which can produce a break in the body or the joint in pipe connections. However, plastic-made manholes promise improved flexibility. Their solvency is shown even during seismic disturbances.
Resistance to Waste Water Effects
Manholes made of bricks and concrete do not resist the impact of wastewater which can corrode the walls because of their agents. Also, concrete manholes do not have lasting resistance to chemical products. But, plastic manholes are resistant to materials such as acids and salts in wastewaters that can harm the environment. Also, these manholes can support chemical waste and landfills which makes them ideal for wastewater evacuation.
Moreover, brick and concrete manholes can suffer from leaks and water infiltration of the soil. But their plastic counterpart ensures there aren’t any leaks because of cracks or porosity and avoids wall infiltration. They have been known for promising lifelong tightness.
Ease of Maintenance
Concrete manholes are rough which require periodic cleaning and maintenance. They tend to keep liquid and solid components that wastewater can drag and leave behind. Plastic manholes, on the other hand, come with an internal flat surface, without any kind of corners and roughness. While these manholes tend to have slopes towards the outlet, this allows an excellent water flow.
Manholes are a significant aspect of people’s lives because they offer access to both public and private employees. However, maintaining and installing them are usually the responsibility of building owners. If you are a building owner and needs a manhole, make sure you contact only the professionals. They will pick the right type of manhole as well as make sure it meets guidelines and codes.
