This is a manhole with excellent chemical resistance and salt resistance, and high freeze-thaw resistance.
The "Resin Manhole" is a prefabricated manhole made by integrally molding resin concrete with reinforcing materials such as rebar. It has high corrosion resistance against sulfuric acid corrosion environments caused by hydrogen sulfide. Since resin concrete is a high-strength and ultra-rapid hardening material, it allows for thinner and lighter products, significantly reducing CO2 emissions during manufacturing, transportation, and installation compared to reinforced concrete products, thus contributing to the prevention of global warming. 【Features】 ■ Excellent chemical resistance ■ Excellent salt resistance ■ High freeze-thaw resistance ■ High wear resistance ■ High strength and good workability *For more details, please download the PDF or feel free to contact us.

basic information
The "Resin Manhole" is a prefabricated manhole that is molded as a single unit with reinforcement materials such as rebar, using resin concrete made by mixing dried aggregates and fillers (filler) with thermosetting resin (liquid resin), without using any cement or water. Due to strong demands for standardization for its use as a manhole pump, the No. 4 manhole was added to the Japan Sewage Works Association standard "JSWAS K-10-2008" as of January 1, 2008, following a revision of the plan. *For more details, please download the PDF or feel free to contact us.*
