Large stacking blocks "Arm Lock"

basic information

- To accommodate the construction of tall slopes, the block control length has been standardized up to 2500mm, allowing for the construction of higher retaining walls compared to conventional methods. - A significant weight reduction of approximately one-third compared to conventional products (based on our company's standards) means that large machinery is not required during construction, enabling economical and efficient wall building. - Designed for horizontal stacking at a 5-degree slope, this allows for safer and quicker construction. - The surface of the blocks features a rough stone-like pattern, creating aesthetically pleasing retaining walls that harmonize with the surrounding landscape. - By incorporating a partition plate on the back of the block, we have improved the workability of backfill materials and core concrete. Additionally, to further enhance efficiency, we also offer embedded formwork boards called "backup boards." - The large stacking block "Arm Lock" is a product exclusive to Nagano Prefecture.
