Ground Investigation Improvement System 'GSIS'

Ground Investigation Improvement System 'GSIS'

Based on technology and on-site know-how, we will strengthen and improve the ground more solidly!

"GSIS" is a ground improvement system that utilizes the ground improvement technology developed through the JOG method to perform more reliable ground improvement. Based on the investigation results from the Swedish sand cone test, it allows for direct injection into the targeted reinforcement areas within the strata, enabling efficient ground strengthening with minimal loss. Since there is no excavation work and minimal impact on adjacent structures, it is well-suited for ground strengthening in areas where buildings are already present. 【Features】 ■ Specialized staff conduct investigations and collect detailed data ■ Injection is performed according to the investigation conditions of each target point to enhance ground bearing capacity ■ The quality of improvement is enhanced by combining investigation and chemical injection ■ Ground strengthening is carried out rationally without unnecessary chemical injection *For more details, please refer to the PDF document or feel free to contact us.

Rooftop greening method - Aqua Soil method

Rooftop greening method - Aqua Soil method

Rooftop greening method: Aqua Soil method

The limited spaces on rooftops, parking lots, and within the premises present a harsh environment for plants to grow. However, the Aqua Soil method revitalizes the inherent strengths of plants while supplementing the lacking elements, allowing them to thrive healthily. Furthermore, the method's significant features of high water retention and air permeability enable a low-maintenance approach by relying solely on rainwater for irrigation. The distinctive fine roots not only avoid damaging the structures but also provide strong support against falling trees. The performance that I want to emphasize the most is "aging change." The Aqua Soil method, with its long track record, does not experience performance degradation such as soil reduction, compaction, or poor drainage over time. Rooftop gardens using the Aqua Soil method maintain their performance for as long as, or even longer than, the buildings themselves. This method fulfills the desire to maintain and enjoy rooftop greening safely and for a long time. 【Features】 ○ High water retention and air permeability. ○ Fine roots not only avoid damaging structures but also provide strong support against falling trees. ○ No performance degradation occurs. ● For other functions and details, please download the catalog.
