At House Stage, we conduct a "Green Test" to diagnose land. We carry out three assessments: "Ground Investigation" to understand the hardness and softness of the ground and any obstacles in the deep layers, "Subsurface Exploration" to check for the presence of underground obstacles, and "Soil Diagnosis" to determine if there is any soil contamination. Selling land with issues such as underground installations, weak ground, or soil contamination can lead to significant problems with business partners later on. By conducting a ground diagnosis, the risks hidden in the land become clear. Would you like to add invisible value and provide land with greater peace of mind? 【Implementation Details】 ■ Ground Investigation ■ Subsurface Exploration ■ Soil Diagnosis *For more details, please refer to the PDF document or feel free to contact us.

The Pure Pile Method is an advanced ground reinforcement technique that enhances traditional columnar improvement methods, providing a safe and high-quality pile foundation with three times the strength, even in humus soil. Since piles are constructed using only cement milk without soil contamination, it achieves uniform and stable high strength regardless of the type of ground. Furthermore, a special excavation rod expands the ground laterally while digging to the support depth, allowing for the construction of the pile body by replacing it with cement milk. 【Features】 - The strength of each pile is approximately three times that of columnar improvement. - Construction time is about half that of columnar improvement. - Minimal residual soil contributes to a cleaner site, demonstrating environmental consideration. For more details, please contact us or download the catalog.

• Ground foundation construction method

The GRR sheet method is a technique that protects valuable properties, such as homes, from uneven settlement by dispersing and equalizing tension and ground forces through the effect of special sheet installation. Since it does not use cement-based solidifying materials or piles, it is also environmentally friendly and does not become a negative legacy. Additionally, the value of a home is not just in the building itself. Ground improvement using cement-based solidifying materials or reinforcement work using piles leaves remnants underground as buried objects. The GRR sheet does not remain in the ground and can be easily removed during rebuilding. 【Features】 - Does not decrease land value - Environmentally friendly and safe for humans - Stable quality - Can be implemented in cultural property burial sites - Highly reliable For more details, please contact us or download the catalog.

The "Pure Pile Method (PP Method)" is an evolved version of the conventional columnar improvement method, providing a safe and high-quality pile foundation reinforcement method with three times the strength, even in humus soil. Since piles are constructed using only cement milk without soil contamination, it can achieve uniform and stable high strength. 【Features】 ◆ Approximately three times the strength of columnar improvement (per pile) ◆ Construction time is about half that of columnar improvement ◆ No soil removal, so there is no leftover soil 【For more details, please download the catalog or feel free to contact us】

• Ground foundation construction method

The "GRR Sheet Method" is a ground reinforcement technique that involves laying "geotextiles" within a crushed stone base of a specified thickness. By utilizing the "rigidity reinforcement effect near the surface due to the crushed stone base" and the "deformation confinement effect of the crushed stone layer provided by the sheet," it is possible to reduce differential settlement and maintain stable structures over time. 【Features】 ◆ All processes are visually observable, ensuring reliable construction management ◆ No curing period is required, allowing for reduced construction time ◆ Can be implemented in narrow spaces as it does not require special dedicated construction machinery 【For more details, please feel free to contact us】

The "Boring Standard Penetration Test" involves drilling into the ground to investigate the properties of soil. It uses the hole to examine the soil's hardness, compaction, soil type, and stratification. Since soil samples can be collected, it allows for direct visual confirmation of the soil's condition. In recent years, liquefaction has been a concern; however, this test can be used to measure water content, enabling the assessment of whether liquefaction will occur when combined with soil quality tests. **Features** - Liquefaction assessment is possible - Soil condition can be confirmed in the vertical direction (columnar diagram) - Soil properties can be understood through physical and mechanical tests **For more details, please download the catalog or feel free to contact us.**

The realization of a dream and one of the greatest projects in life: a home. As the construction plan progresses, the image of the home that the customer envisions becomes clearer. Budget and location decisions follow, and then considerations about the floor plan, exterior wall colors, and so on... However, at this stage, unless one has knowledge about construction, discussions about the ground conditions rarely come up. While awareness of ground conditions in the housing industry has deepened today, in reality, most customers have a limited understanding of ground conditions. As a result, during the planning phase, they often find themselves shocked by unexpected expenses depending on the results of the ground survey. To avoid such situations, we recommend conducting a ground survey early on. ◎ Ground Survey... → If deemed weak, reinforcement is necessary. → Building on solid ground is the best approach. ↓↓ For more details, please contact us ↓↓

There are several methods for ground investigation, but a representative one is called the "Swedish Sondage Test," named because it was used during the construction of the national railway in Sweden, a Nordic country. This test allows for the examination of the conditions within the ground. Currently, this method is used in most places for the ground of general residential buildings in Japan. It has a significant advantage as it uses relatively simple equipment, making it possible to conduct investigations in narrow spaces. 【List of Investigation Examples】 ○ Swedish Sondage Test (SWS Test) ○ Standard Penetration Test ○ Ram Sondage Test ○ Plate Load Test ○ Simple Dynamic Cone Penetration Test ↓↓ For more details, please contact us or download the catalog ↓↓

The surface improvement method involves mixing soil with a cement-based solidifying agent to create an artificially hard and uniform ground, approximately 1 meter thick, beneath the foundation. After mixing the soil and cement-based solidifying agent, heavy machinery is used for compaction to solidify the ground. If care is not taken at this stage, a good ground will not be achieved. Thorough compaction is essential for surface ground improvement. ↓↓ For more details, please contact us. ↓↓

The wet column improvement method involves mixing soil and cement milk to create columnar bodies with a diameter of 400mm to 800mm within the soil. These thick and large columns support the house due to their friction resistance. If the soil and cement milk are mixed carelessly, a proper columnar body cannot be formed. Columnar improvement relies on careful mixing. ↓↓ For more details, please contact us. ↓↓
