We would like to introduce our "CLT construction method." CLT stands for Cross Laminated Timber, which is a large wood panel building material made by gluing layers of boards (lamina) together with their fiber directions intersecting at right angles. Since CLT panels are manufactured and processed in a factory, the burden of on-site work is reduced. The panels themselves serve as columns and beams, allowing for construction without the need for skilled technicians. 【Features】 ■ Fast processing with large panels ■ Earthquake-resistant, fire-resistant, and energy-efficient ■ Utilization of forest resources ■ The panels themselves serve as columns and beams, enabling construction without the need for skilled technicians *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our 'CCB Method' for controlling the occurrence of shrinkage cracks in reinforced concrete walls. It is possible to guide cracks to the induced joint and prevent cracks from occurring on the wall surface outside the joint area. The features of this method include placing the crack-inducing material and wall reinforcement bars in a straight line as a means to ensure a non-concrete ratio where cracks are desired, as well as using large-diameter deformed bars as the crack-inducing material. 【Features】 ■ Control the occurrence of shrinkage cracks in reinforced concrete walls ■ Guide cracks to the induced joint ■ Prevent cracks from occurring on the wall surface outside the joint area ■ Place crack-inducing material and wall reinforcement bars in a straight line *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Mud Density Method" for thrusting, which can accommodate various soil types through head replacement. In this method, high-density mud water is pumped to the tip of the thrusting machine, stabilizing the face while rotating the cutter to advance, and soil is removed using a vacuum pump. The standard thrusting distance is approximately 100m to 300m per span, but thrusting over 500m is also possible. Additionally, curved construction can be performed. 【Features】 ■ Adoption of overcut ■ Stability of tail void ■ Achievement of low thrusting force ■ Realization of sharp curve thrusting ■ Smooth removal of cobbles ■ Fresh air is always supplied inside the pipe *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Shield Method" for constructing tunnels underground. Using a tunnel boring machine called a "shield," we advance underground while preventing soil collapse, safely conducting excavation and lining work inside to build the tunnel. This method adapts to a wide range of soil types and minimizes subsidence. It is also suitable for depths of over 50 meters underground. 【Features】 ■ Adaptability to a wide range of soil types ■ Minimization of subsidence ■ Simultaneous backfill injection is possible ■ Suitable for deep depths and high water pressure *For more details, please refer to the PDF materials or feel free to contact us.

The "SPR method" is a rehabilitation method that uses a self-propelled pipe manufacturing machine to create a PVC rehabilitation pipe inside an existing pipe. It can be completed quickly without the need for excavation while maintaining water flow. Additionally, it forms a continuous pipe without joints, demonstrating excellent water tightness. It can restore strength beyond that of new pipes, making it suitable for addressing aging pipelines such as sewer pipes and agricultural water pipes. 【Features】 ■ Can be constructed without digging up the road ■ Construction is possible while maintaining water flow ■ Self-propelled system accommodates long-distance and curved construction ■ Enables seismic retrofitting of pipeline facilities *For more details, please refer to the PDF materials or feel free to contact us.

The "TRD Method" achieves remarkable high precision and high capability construction, realizing cost savings through shortened construction periods. A chainsaw-type cutter inserted into the ground is connected to a base machine, which moves laterally to excavate trenches, inject solidifying agents, and mix and stir with in-situ soil, creating a continuous wall underground. Core materials such as H-beams can be inserted and applied as a soil retention and waterproofing wall during underground excavation, and it can also be used for liquefaction countermeasures, ground reinforcement, and groundwater blocking. 【Features】 ■ No risk of tipping, exceptional stability ■ Achieves remarkable high precision and high capability construction, realizing cost savings through shortened construction periods ■ Core material spacing can be set arbitrarily ■ Seamless and aligned construction ■ Smooth and beautiful constructed wall surfaces *For more details, please refer to the PDF materials or feel free to contact us.

"CLT" is a large wood panel building material made by laminating boards (lamina) with the fiber direction intersecting at right angles in each layer. It does not require curing time like concrete, allowing for quick assembly of factory-processed products on-site. As a result, construction time is shortened, and costs can be reduced. [Features] ■ Fast construction with large panels ■ Excellent thermal performance ■ Warm and inviting spaces ■ Utilization of forest resources *For more details, please download the PDF or feel free to contact us.
