Corrosion Proof Polymer Concrete Manholes & Structures: Where to Use Them in Design & Why

There are a lot of discussions in the engineering community about corrosion-proof polymer concrete manholes and structures. Are they really that great? Does it make sense to use them in design?  In this article, we will cover the basics of corrosion-proof polymer concrete, where to use them in design, the benefits they offer, and more. To help make this article more accessible, we’ve also included a section on life cycle cost analysis and polymer concrete specification. What is Corrosion? Corrosion is a major problem in wastewater  systems because of the presence of hydrogen sulfide gas. This gas is generated by Thiobacillus Bacteria which oxidizes to form sulfuric acid. The sulfuric acid then attacks the cement which acts as the glue holding the aggregates together, causing the concrete to deteriorate. Aggregates are also susceptible to corroding in most concrete structures. Once corrosion begins, the integrity of the entire structure is at
