High corrosion-resistant molten zinc coating with a lifespan of 80 to 100 years.

The "Permanent Drainage Reinforcement Pipe (PDR Method)" is a construction method that involves installing a copper pipe with a diameter of approximately 6 cm, processed with a strainer, into a slope. This method not only functions as a drainage pipe but also reinforces the surrounding ground. Additionally, it is suitable for seismic reinforcement measures as it quickly dissipates excess pore water pressure generated during strong vibrations from earthquakes, while simultaneously enhancing the soil's rigidity. 【Features】 ■ A reinforced soil method with drainage functionality ■ Very cost-effective and provides significant reinforcement effects due to its insertion method ■ Extensive track record with over 1 million units used in projects such as the Tōkaidō Shinkansen ■ Affordable and easy to install, making it suitable for seismic reinforcement work on residential landfills and retaining walls ■ Ideal for preventing collapses of road embankments during heavy rain or earthquakes *For more details, please download the PDF or feel free to contact us.
