We have published the October issue of Eco-Rokka News, featuring an introduction to screw piles!
At Air Water Ecrocca Co., Ltd., we publish the "Ecrocca Newsletter," which introduces Ecrocca products once a month. The October issue of the Ecrocca Newsletter features the introduction of screw piles. "Screw piles" are friction piles that change the common understanding of foundation methods. They are simpler and more cost-effective than traditional concrete foundations used for wooden decks. The friction pile method minimizes the impact on the ground surface and is suitable for foundation work in difficult locations such as slopes and waterfronts. By combining them with the V-deck series, which has water resistance, electrical insulation, and high weather resistance, installation near water bodies becomes easier. This document provides detailed information about screw piles. We encourage you to read it. *You can view the October issue of the Ecrocca Newsletter from the "Related Materials." *For more details, please feel free to contact us.
