You’ll find numerous benefits to fiberglass manholes that are inherent in their design, including easy access to underground flow channels and numerous cover options that allow them to be safely installed virtually anywhere. Not all fiberglass manholes are created equal, however, as you’ll find quite a wide variety to choose from to find the best performance. Learn about all the benefits of fiberglass manholes.
Monolithic Construction
Fiberglass manholes are constructed as a single piece. While multiple pieces may be crafted during the production process, the final result that reaches the installation site will always be a singular piece by that point. This is particularly beneficial compared with the segmented nature of concrete manholes.
Segmented concrete manholes have to be installed by sections, and those sections are sealed with watertight materials. While they will work in the short term, eventually they decay and can fail. With fiberglass, you’ll never have to worry about that kind of problem, as there’s no bonding material to decay in the first place.
Corrosion Resistance
Wastewater flows are almost always inherently corrosive. There’s really no way around that, so you’ll have to make sure your manhole can handle the conditions to keep your flow measurement efforts secure for as long as possible. Fortunately, fiberglass is built to withstand corrosive forces for a long time. In fact, the resin-covered interior acts as an additional barrier to corrosion in conjunction with the fiberglass itself.
While concrete manholes hold up pretty well, they can’t match the longevity of their fiberglass counterparts. To even stay competitive, concrete manholes need protective spray coatings applied to the interior, and this has to be repeated several times throughout the manhole’s life cycle. With a fiberglass manhole, you can easily go decades without worrying about the coating.
Cost-Effectiveness
Maximizing benefits as much as possible is always nice, but many people have to consider cost before all else. Fortunately, fiberglass manholes are the best option when it comes to cost. This may seem odd, because a packaged metering manhole made out of fiberglass is more costly than its concrete counterpart, but this cost must be examined as part of the total expense of operating a manhole.
Overall, fiberglass is the more affordable material. This is thanks, in large part, to its longevity. You don’t have to worry about corrosion or decaying sealing materials, so maintenance is much easier. Additionally, the monolithic nature of fiberglass makes the installation process easier, so you won’t have to spend as much on labor.
