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.

• Inspection hatches, manhole covers, and ditch covers

Resin concrete is a material that does not use any cement or water, but instead combines dried aggregates and fillers with a thermosetting resin (liquid resin) as a binder, mixing and solidifying them. 'JSWAS K-12' is an excellent resin concrete pipe for advanced construction methods that meets all the functional requirements of modern sewer pipelines. Resin concrete has more than ten times the wear resistance compared to ordinary cement concrete, making it effective in areas where wear due to flowing gravel and water pressure is a concern. 【Features】 ■ Internal water pressure resistance ■ Roughness coefficient ■ Pipe pressure comparison ■ Corrosion prevention ■ Long-distance and sharp curve construction compatibility * There is also a resin concrete pipe for open-cut construction methods, 'JAWAS K-11'. * For more details, please download the PDF or feel free to contact us.

The "RMI Method" is a rehabilitation method using resin manholes. The inserted resin manhole ensures self-supporting strength on its own. It has acid resistance equivalent to newly installed resin manholes. Additionally, it is adaptable to seismic levels 1 and 2, and it is a method that does not require special technology or machinery. 【Features】 ■ Workability ■ Acid resistance ■ Load capacity ■ Water tightness ■ Seismic resistance *For more details, please download the PDF or feel free to contact us.
