During heavy rainfall, rainwater that falls in the garden is temporarily stored underground! This helps prevent urban flooding.
We would like to introduce examples of rainwater storage tanks and rainwater infiltration tanks utilizing Super Soil. In particular, in areas where urbanization has progressed, it has become difficult for rainwater to infiltrate underground, leading to urban flooding that flows into rivers in a short period of time. By utilizing the water retention capabilities of Super Soil, it is being used as a rainwater storage tank to temporarily hold rainwater, as well as a rainwater infiltration tank that slowly allows the stored rainwater to infiltrate over time. 【Example Overview】 ■ Application Category: Rainwater Storage, Rainwater Infiltration Tank, Rain Garden ■ Client: Private Sector ■ Construction Location: Toyohashi City, Aichi Prefecture ■ Porous ■ Water Retention and Drainage *For more details, please download the PDF or feel free to contact us.

"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.
