High storage capacity with a porosity of over 95%! Excellent seismic strength and easy to assemble.

【Product Features】 ■Easy Maintenance 　　→Installed a "Sediment Tank and Non-Dust System" as an inflow tank 　　　Easily maintainable by removing the sand accumulated in the inflow tank without allowing soil particles to enter the storage tank. ■High Porosity of Over 95% 　　→Ensures a practical porosity of over 95% after assembly (for facilities with a height of 1.2m or more). ■Cost Reduction 　　→Reduces excavation and residual soil volume due to high porosity, thereby lowering total costs. ■Simplification of Construction Work 　　→Each unit weighs only 6.8 kg, making assembly easy by simply connecting dedicated joints. ■Sufficient Compressive Strength 　　→Compatible with T-25 load, suitable for installation in areas requiring strength, such as under parking lots. 　　　It meets Level 2 seismic motion and has sufficient earthquake resistance. ■Reliable Performance and Quality 　　→Obtained technical evaluation certification from the Public Interest Incorporated Association for Rainwater Storage and Infiltration Technology. 　　　Certification updated as of April 1, 2019. ●Construction Status and Installation Example Photos ●Layout and Structural Diagrams ●Photos, Dimensions, and Materials of Each Component ●Introduction of Associated Facilities such as Inflow and Inspection Facilities for "Pradam-kun" For more details on the "Rainwater Storage and Infiltration Facility / Rainwater Storage Tank 'Pradam-kun'," please refer to the 【Download Catalog】.
