"Super Sol" is a lightweight material recycled from glass bottles and other sources. It is an amorphous, gravel-like artificial pumice made by crushing and sintering waste glass into particles ranging from 2 to 75 mm in size. Utilizing its characteristics such as lightweight, permeability, water retention, non-combustibility, and thermal insulation, it is used in a wide range of applications including civil engineering, greening, agriculture, water purification, and insulation. In particular, "Glass Foam Recycled Material - Super Sol" as a civil engineering material has a unit weight of about 4 kN/m3, which is approximately one-fifth that of conventional fill materials, making it very lightweight. When this lightweight fill material is used on soft ground, it allows for the construction of embankments and other structures without the need for foundation improvement, which can be economically advantageous. 【We are currently offering a catalog of products by application as a gift!】 ■ Lightweight fill material "Super Sol L2" ■ Greening material "Super Sol L1" ■ Agricultural material "Super Sol L1" ■ Purification material "Super Sol L2・L4" ★ Eco Mark certified, with registration records in NETIS!

To reduce the load on the box culvert due to road pavement improvements, we aimed to lighten the backfill. 【Construction Case Study】 ○ Project Details: National Disaster No. 23-71-506-0-008 Road (North 5, North 8) Disaster recovery and ground improvement work ○ Use Category: Civil Engineering / Structural Protection / Existing Structures ○ Client: Ibaraki Prefecture ○ Construction Location: Naka District, Ibaraki Prefecture ○ Required Performance: Lightweight and load reduction For more details, please contact us or download the catalog.

We will introduce a case study of the construction of "Super Sol," an artificial lightweight material made from crushed and sintered waste glass. This case involves the lightweighting of the rooftop of a water distribution facility in Kawasaki City, which is being utilized as a futsal court (artificial turf). Super Sol was adopted for the installation of a protective net. It was used to reduce the load on the facility and improve drainage for the futsal court. The construction was carried out in the following order: Super Sol application → leveling → crushed stone application → compaction. 【Construction Case Study】 - Construction Details: Installation of a protective net at Frontown Saginuma - Usage Category: Civil Engineering / Structural Protection / Existing Structures - Client: Private - Construction Location: Kawasaki City, Kanagawa Prefecture - Required Performance: Lightweight, load reduction, drainage 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, in the context of reducing the weight above an underground parking lot. In the landscaping work at the fountain square of Shinjuku Station's west exit, lightweight Super Sol was used to reduce the load on the drainage base material and the underground parking lot. A cage mat was used to secure the underground pillars supporting the tall trees, and Super Sol was filled into the cage as the drainage base material. 【Construction Case Study】 - Project Details: Renovation work for the fountain area of Shinjuku Station's west exit square - Usage Category: Civil Engineering / Structural Protection / Existing Structures - Client: Tokyo Metropolitan Government - Construction Location: Shinjuku Ward, Tokyo - Required Performance: Lightweight, Load Reduction, Drainage Capability For more details, please contact us or download the catalog.

We would like to introduce a case study of the construction of "Super Sol," an artificial lightweight material made by crushing and sintering waste glass. This case study focuses on the protection of arch culverts. Super Sol was used as lightweight fill to reduce the load on the arch culverts and decrease the earth pressure on the reverse T-shaped retaining walls. The material allowed for flexibility in construction on complex terrains and contributed to shortening the construction period. 【Construction Case Study】 - Project Details: Improvement of the Nanbara Fuchinen Line Road - Application Category: Civil Engineering / Protection Structures Backfill / New Retaining Structures - Client: Okinawa Prefecture - Construction Location: Chinen Village, Okinawa Prefecture - Required Performance: Lightweight, Load Reduction, Earth Pressure Reduction For more details, please contact us or download the catalog.

We would like to introduce a case study of the construction of "Super Sol," an artificial lightweight material made by crushing and sintering waste glass into a foamed state, specifically for the protection of buried pipes. In the development of a residential area, there were existing buried pipes directly beneath the planned road. Instead of replacing the buried pipes, it was more cost-effective to protect them using lightweight fill, so lightweight fill construction was adopted. After comparing with other lightweight materials (specific gravity over 1.0), Super Sol was chosen as it required the least depth for replacement. 【Construction Case Study】 ○ Project Details: Construction of the Bijogi Housing Complex ○ Usage Category: Civil Engineering / Structural Protection / Underground Buried Objects ○ Client: Private ○ Construction Location: Sakura City, Tochigi Prefecture ○ Required Performance: Lightweight and reduced load-bearing capacity 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," which is made from crushed and sintered waste glass. This case involves the backfilling of a retaining wall. In the auxiliary works of the bridge, Super Sol, which has high permeability, was applied as river embankment material. It was used as backfill material for block masonry, and some areas were constructed with lightweight mixed soil (60% Super Sol and 40% soil). 【Construction Case Study】 - Project Details: Auxiliary works for the Goro Fureai Bridge - Usage Category: Civil Engineering / Structure Backfill / Retaining Wall - Client: Mizuho City - Construction Location: Mizuho City, Gifu Prefecture - Required Performance: Lightweight and reduced soil pressure For more details, please contact us or download the catalog.

About the Glass Foam Material Business Cooperative From an era of mass production, mass consumption, and mass disposal to an era where waste is utilized as a valuable resource. To effectively use limited Earth resources, environmental technology has been developed to transform waste glass into an excellent material. This is the glass foam lightweight material "Super Sol." Currently, Super Sol is manufactured at 17 locations nationwide. While each Super Sol manufacturing plant supplies high-quality and safe products, we are also building a network between locations to spread the excellent characteristics of Super Sol and promote its expansion. Therefore, we established the Glass Foam Material Business Cooperative. What is Super Sol? A lightweight civil engineering material with excellent workability. Super Sol L2 is a lightweight embankment material made from 100% waste glass. With a specific gravity of 0.35 to 0.5, it is 1/5 to 1/7 the weight of ordinary soil, reducing soil pressure on structures and being widely utilized as embankment material on soft ground.
