30 years of development! Introducing the rainwater infiltration basin, essential for rainwater runoff control facilities.
We would like to introduce the "Rainwater Infiltration Basin" handled by Kokka Corporation. The area around the basin is backfilled with crushed stone, allowing the collected rainwater to infiltrate into the relatively shallow parts of the ground from its bottom and sides. We offer a wide range of products, including the "JKC," which prioritizes safety by reducing the size of the grating, the maintenance-friendly "KM," and the compact "TRX," which has an internal diameter of 400. 【Product Lineup (Excerpt)】 ■ Integrated Edge Block Type "JKC" ■ KM ■ PRX ■ Infiltration Heavy-Duty Angle Basin ■ Trex Basin "TRX" *For more details, please refer to the PDF document or feel free to contact us.
