[Super Soil Construction Case] A2 Tsunami Evacuation Road Widening Project Case
Super Sol L2
This is a case of road improvement work on City Road No. 3225 in Hitachi City, Ibaraki Prefecture.
We would like to introduce a construction case study of the artificial lightweight material "Super Sol," made from crushed and sintered waste glass, used in the "Tsunami Evacuation Road Widening Project." In this disaster prevention project, a narrow coastal road was widened to serve as a tsunami evacuation route, and Super Sol was adopted as backfill material for the retaining wall. The lightweight Super Sol was effective in reducing soil pressure, allowing for a thinner retaining wall. Due to the narrow and nearly vertical construction site, the material could be lifted and placed in bags, making the construction process very easy, which received positive feedback. 【Construction Case Study】 - Project Details: Improvement work on City Road No. 3225 - Usage Category: Civil Engineering / Backfill for Structures / Retaining Wall - Client: Hitachi City - Construction Location: Hitachi City, Ibaraki Prefecture - Required Performance: Lightweight, Soil Pressure Reduction, Workability For more details, please contact us or download the catalog.

Company information
"Super Sol," made by crushing and sintering waste glass, is a lightweight material with countless holes, forming a porous structure. It is an artificial lightweight stone with an irregular shape and a particle size of 2 to 75 mm. There are products with varying specific gravities and water absorption rates to suit different applications. Composed of soil components, it is an eco-friendly product with an eco-mark. **Features of Super Sol:** - **Lightweight:** It is 1/6 to 1/5 the weight of soil, with a proven track record as a lightweight fill material. By combining it with crushed stone, the unit weight can be controlled between 4 kN/m³ and 11 kN/m³. - **Drainage:** It can be used as a drainage material in civil engineering and greening projects. - **Aeration and Water Retention:** It can be used as an inorganic soil amendment for greening. - **Workability:** Its lightweight nature makes it easy to handle, facilitating construction in uneven terrains and confined spaces. Like crushed stone, it can be installed through leveling and compaction without the need for curing periods or special techniques. - **Stability:** Being mineral-based and inorganic, it is physically and chemically stable, with no corrosion. - **Safety:** As it is made from naturally derived glass, Super Sol is composed of soil components, making it a highly safe material for the surrounding environment.
