The primary purpose of a manhole is to offer access to the stormwater line or sewer. Manholes are also important for maintenance and ventilation. Traditionally, manholes were made of metal or precast concrete, but now we have plastic manholes. Yes, plastic manholes do exist and are quite popular as an alternative to precast concrete. Besides the fact that plastic manholes are corrosion resistant, there are several other advantages. Here are some of the ones you need to know.
- Simplified installation. In case of precast concrete manholes, everything has to be assembled on site, and that involved considerable work. The same is true with metal manholes, and to add to that, these are bulky materials, so there is an added cost of transportation. Since plastic manholes are lightweight and easy to transport, expenses can be a minimized and the process of installation is extremely simple.
- Resistant to water and corrosion. Even the best metal manholes are prone to corrosion, and there are issues as far as salt and acidic materials are concerned. With plastic manholes, municipalities can finally have a more permanent solution that doesn’t require as much attention as far as durability is concerned.
- Almost no maintenance. The best part about plastic manholes is the lack of maintenance. Most companies that deal in such products make manholes with no seams and joints, so there is no need to spend on maintenance. Also, inspection is handy for sure, but again, it doesn’t have to be a complicated affair.
- Advantage of cheaper pricing. Manufacturing plastic manholes is easier than most people imagine, because a molding technique called rotomolding is used for it. Rotational molding is one of the most reliable means of production for creating large, hollow products, and if used effectively, the plastic manholes produced would last for decades.
It goes without saying that the quality of plastic manholes does matter, and buyers, including municipalities and private property owners, should be careful from where they source the products from. The good news is it is possible to customize plastic manholes as per requirements, and the manufacturer will check for all aspects before designing. Find a manufacturer that can be relied on and has experience with rotational molding. With durable plastic manholes, everything from purchase and installation to maintenance gets easier, and there wouldn’t be any need to think of the heavy concrete or metal options anymore.
