■Correction of Building Tilt and Ground Improvement Method Directly Under the Building "Comprehensive Catalog" This catalog introduces methods for correcting tilted buildings and creating ground that does not subside again. With extensive experience and knowledge in ground and construction, we can read necessary information from surveys and clarify the causes of subsidence. Based on a comprehensive understanding of various situations, we propose the most suitable methods tailored to your needs. We adopt hybrid methods that combine techniques according to the structural issues of the building, construction conditions, and the underground (ground) situation, providing proposals, designs, and construction that meet diverse needs. 【Featured Methods】 ○ High-Pressure Jet Mixing Method (Small Diameter Type, Medium to Large Diameter Type) ○ Underpinning Method ○ Side Pinning Method (Helical Pile Method) ○ GSIS Method ○ JOG Method For more details, please contact us or download the catalog.

■Selecting and implementing the optimal construction method with reliable technology and extensive experience■ With our extensive knowledge of ground and construction based on rich experience, we interpret the necessary information from surveys to clarify the causes of subsidence. We select appropriate construction methods while considering the situation and carry out the implementation. Sometimes, we adopt hybrid methods that combine different techniques to meet diverse needs. We can propose appropriate modification and reinforcement work for a wide range of structures and ground conditions, including factories, warehouses, stores, and public facilities. We correct the tilt of existing buildings and construct a solid foundation directly beneath them to prevent further subsidence. ★You can view our 'Comprehensive Catalog' introducing the construction methods we handle by downloading the PDF. 【Listed Construction Methods】 ■High-pressure injection mixing method ■Underpinning method ■Side pinning method (helical pier method) ■GSIS method ■JOG method ■TerraTech method Please feel free to contact us.

The "JOG Method" does not require excavation work on the outer perimeter, resulting in a shorter construction period, and it is a method that does not apply localized forces to the structure. By injecting grout material under the foundation while controlling it with a computer, we can correct any tilting. The formulation of a two-component grout material injected through a double pipe allows us to set the curing time according to the ground and construction environment. We construct improved ground to ensure ground reaction force, and further correct tilting by pressing in quick-setting grout. 【Features】 ■ No excavation work on the outer perimeter is necessary ■ No localized forces act on the structure ■ Applicable for large buildings exceeding 10 stories *For more details, please refer to the PDF document or feel free to contact us.

The "GSIS Method" is suitable for ground reinforcement in areas where buildings already exist, as it does not involve excavation work and has minimal impact on adjacent structures. Based on meticulous survey results, the method allows for direct injection of agents into weak ground layers, enabling efficient ground reinforcement with minimal loss. [Features] - Ideal for ground improvement beneath existing buildings - No excavation work, resulting in minimal impact on adjacent structures *For more details, please refer to the PDF materials or feel free to contact us.

"Side Piling Method (Helical Pile Method)" Using a dedicated machine, a helical pile with a connecting spiral plate is rotated and pressed into the supporting ground, increasing the load-bearing capacity of the building and preventing settlement. A hydraulic jack is attached to the bracket section to correct any tilt. The tilt correction can be repeated. This method is suitable for small-scale structures. 【Features】 ■ Can be constructed even during ongoing settlement ■ Can be constructed in narrow spaces (at least 50 cm distance from neighboring properties) ■ Ideal for correcting external structures *For more details, please refer to the PDF materials or feel free to contact us.

"Underpinning Method" This method involves extending steel pipes beneath the foundation of a structure while using the building's own weight as a reaction force. The steel pipe piles are driven into the ground, and by performing a jack-up at the top of the steel pipe piles, the tilt of the building is corrected. Since the steel pipe piles are driven down to the supporting ground and act as support piles, there is no risk of the building settling again. This method is suitable for small to medium-sized structures. 【Features】 ■ Can be implemented even for heavy structures ■ Selection of steel pipe diameter based on load ■ Flexible arrangement of steel pipes *For more details, please refer to the PDF document or feel free to contact us.

The "High-Pressure Jet Mixing Method" has a wide range of applications and can also be used for soft ground to improve and strengthen the soil. Cement-based solidifiers are injected at high pressure and rotated into the weak ground between the building and the supporting ground, mixing and stirring the soil and solidifier while cutting into the ground. This creates a uniform cylindrical improved body. The improved body also serves as a supporting pile. It can be adjusted to achieve the desired improvement strength suitable for each design condition. Please feel free to contact us. Toll-free number: 0120-873-835

"Permeation Solidification Injection Method" This is a permanent chemical injection method that selects injection materials and methods based on ground information to strengthen the ground and prevent water infiltration. It uses durable grout materials to permeate a wide area for ground improvement. 【Features】 ■ Permanent ground improvement ■ Allows for significant reduction in the number of injections, as it can permeate the agent over a wide area at low pressure from a large injection source ■ No surface uplift occurs after injection ■ No excavation work is required, thus no impact on adjacent structures ■ Minimal sludge discharge *For more details, please refer to the PDF materials or feel free to contact us.
