This case involves the use of L2 and L4 behind a retaining wall. Super Sol was adopted for the access road (sidewalk) of the bridge. Considering the impact of water, Super Sol L4 with a specific gravity of 1.1 was laid below the high water level, while Super Sol L2 with a specific gravity of 0.4 was used above the high water level, utilizing a two-layer system. 【Construction Case Study】 - Project Details: Nago Castle Park Stream Square Pedestrian Bridge Improvement Project - Usage Category: Civil Engineering / Lightweight Fill Structure Backfill / Roadbed Retaining Wall - Client: Okinawa Prefecture - Construction Location: Nago City, Okinawa Prefecture - Required Performance: Lightweight, Soil Pressure Reduction, Strength For more details, please contact us or download the catalog.

We would like to introduce a case study of the construction using "Super Sol," an artificial lightweight material made from crushed and sintered waste glass, as backfill material for a seawall. In the coastal protection project, Super Sol L4, which has a specific gravity of 1.1 and is lighter than gravel or crushed stone but sinks in water, was adopted. Initially, other lightweight fill materials that sink in water were included in the design, but Super Sol was chosen due to its ease of compaction and resistance to material change, based on its slaking rate and crushing characteristics. 【Construction Case Study】 - Project Details: Nago Fishing Port - 4.5m Seawall Improvement Project - Usage Category: Civil Engineering / Structural Backfill / Seawall - Client: Okinawa Prefecture - Construction Location: Nago City, Okinawa Prefecture - Required Performance: Lightweight and reduced earth pressure For more details, please contact us or download the catalog.

We would like to introduce a case study of the construction of the artificial lightweight material "Super Sol," made from crushed and sintered waste glass, specifically for the oxygen pipes and drainage base. In the landscaping work for the hotel garden, Super Sol L1 medium grain was used for the drainage base material and oxygen pipes. Due to the clayey ground at the construction site, which has very poor drainage, measures were necessary. During the transplantation of a 10-meter-high Himalayan cedar, a drainage layer was created at the base, and nine oxygen pipes were installed. The air permeability and drainage have improved, and the progress is favorable. 【Construction Case Study】 - Project Details: Hotel Okura Frontier Hotel Tsukuba Annex Square Construction - Usage Category: Greening / Oxygen Pipe Drainage Base / Below Planting - Client: Private - Construction Location: Tsukuba City, Ibaraki Prefecture - Required Performance: Air permeability, drainage, strength For more details, please contact us or download the catalog.

We would like to introduce a case study of the artificial lightweight material "Super Sol," made from crushed and sintered waste glass, used for rainwater retention in schoolyards. The rainwater retention system utilizing Super Sol can maintain water quality without circulating the stored rainwater, allowing for low-cost installation and reduced running costs. It is used for irrigation of plantings on a daily basis and can be utilized as emergency water during disasters, contributing to the conservation of water resources. This project was completed through the Ministry of Land, Infrastructure, Transport and Tourism's "Frontier Project by Construction Companies." 【Case Study】 - Project Details: Greenery project with Super Sol water retention function at Furukawa Elementary School, Naha City - Usage Category: Purification / Rainwater retention tank filling material / Schoolyard greening - Client: Ministry of Land, Infrastructure, Transport and Tourism - Location: Naha City, Okinawa Prefecture - Required Performance: Porous / Corrosion suppression For more details, please contact us or download the catalog.

We would like to introduce a case study of the construction of an artificial wetland using the lightweight material "Super Sol," which is made from crushed and sintered waste glass. This system, developed through a collaboration between industry, academia, and government by the National Agriculture and Food Research Organization, purifies high-concentration organic wastewater mixed with manure and milk from dairy farms to a level suitable for river discharge. Super Sol is used as a lightweight floating material on the surface of the wetland. It prevents clogging and provides insulation, allowing for wastewater treatment to begin immediately after installation. 【Construction Case Study】 - Project Details: Purification of dairy wastewater using a subsurface flow reed bed artificial wetland - Application Category: Dairy farming / Lightweight floating material / Parlor wastewater purification - Client: Private sector - Construction Location: Bekkai Town, Hokkaido - Required Performance: Porous, lightweight, and insulating For more details, please contact us or download the catalog.
