"EP Sleeve," a non-corrosive polyethylene pedestrian passage that contributes to flood prevention measures.

The trend of installing rainwater retention tanks in "underground pits" rather than "outdoor buried" locations is increasing in urban areas due to site constraints, construction feasibility, maintenance management, and the advancement of flood control measures. Utilizing underground pits contributes to the effective use of above-ground space and reduces risks during disasters, but the durability of the installed equipment becomes crucial. Our all-resin pedestrian access "EP Sleeve" provides a highly reliable solution to these challenges through the use of non-corrosive materials and extended lifespan. 【Usage Scene】 As a pedestrian access point when installing water tanks in underground pits. 【Implementation Effects】 - Non-corrosive material "ALL polyethylene material" - Improved efficiency in cleaning and maintenance work * Of course, it also contributes to "labor-saving" with lightweight resin during the construction process! * For more details, please feel free to request the catalog directly via email or download it from the "EPJ Corporation" "Ipros Special Site" through the related link.
