  Diaphragm wall construction method(7)

  We are implementing construction methods such as the "TRD method," which can be applied as a soil retention and waterproofing wall during underground excavation, as well as the "CCC method" and "mini-wall method." Additionally, we can use the "bubble excavation method" in conjunction, which contributes to reducing mechanical load and industrial waste.

• Ground investigation(1)

  Effects of improved ground and its use in liquefaction surveys.

• 

  Underground Obstacle Removal Method(3)

  We are implementing the "Hiro Work kmighty method," which involves the complete removal of existing foundation piles, as well as the "Bauer method" and "Super Top method" for excavating and removing obstacles. The "Bauer method" is used when the depth is shallow or when construction is close to narrow spaces or structures. The "Super Top method" is applied in cases of deep depths or hard ground.

• 

  Soil improvement method(1)

  The "rotary crushing and mixing method" enables the effective utilization of all construction-generated soil! Additionally, it can provide "debris-mixed soil" generated during disasters as high-quality soil!

• 

  Structural repair method(1)

  Restoration of subsidence in structures requires various foundation reinforcement methods due to differing ground conditions. Based on the results of preliminary investigations, we will propose the most suitable subsidence restoration method. In conventional subsidence restoration work, the demolition of the first-floor slab caused inconvenience to the client's daily life; however, our company can perform foundation reinforcement and level adjustment while allowing for normal daily activities.

• 

  Slope construction method(3)

  We are implementing the "RBP Wall Method" for soil cutting and reinforcement, and the "NSPC W Method" for lightweight embankment construction. Through road widening, land development, reinforcement of existing structures, disaster recovery, riverbank protection, and steep slope countermeasures, we contribute to the creation of safe and secure towns.

• 

  Construction work(4)

  "Total support from the ground to the building" - We create a more secure and safe living environment for our customers through new construction, renovations, repairs, energy-saving measures, foundations, and underground measures (liquefaction and wells), among others.

• 

  Ground improvement methods (chemical injection and permanent grout method)(3)

  We are engaged in the construction of the "double pipe strainer method" as well as the "double packer method." Additionally, we have developed our own methods, including the "high grip grout method" and the "ultra-multipoint DP method," which reduce injection loss.

• 

  Ground improvement method (high-pressure jetting)(4)

  We are implementing various construction methods, including the core methods "JSG Method" and "CJG Method" of high-pressure jet mixing, which enable fast construction and have achieved a reduction in the amount of hardening material and sludge discharge, such as the "RJP Method" and "PJG Method," as well as the "MJS Method," which allows for slanted and horizontal construction, and the "Multi-Jet Method," which enables free shapes of improved bodies.

• 

  Ground improvement method (mechanical mixing)(5)

  We carry out construction using various methods, including the "Shallow-Deep Four-Axis Method," which allows for flexible ground improvement even in narrow construction sites, as well as the certified "TSC Method," "SAT Column Method," and "CDM-Land4 Method."

• 

  Bored pile construction method(2)

  A low headroom sliding method using an all-casing (full rotary) construction technique that allows work up to a headroom limit of 4.4 meters. For place-driven piles in ground with boulders or bedrock, construction is carried out using the super top method.

• 

  Soil purification method(3)

  We are implementing the "iron powder bubble method," which encapsulates iron powder in bubbles to ensure reliable liquid delivery underground, as well as the "mechanical stirring method" and the "ultra-multipoint DP method."

• 

  Liquefaction countermeasure construction method(4)

  We are implementing the simultaneous embedding method "OHO Drain Method," which suppresses the discharge of excavated soil to the surface and allows for the installation of drainage materials at a specified depth simultaneously with the completion of drilling, as well as construction methods for liquefaction countermeasures such as "High Grip Grout Method" and "Ultra-Multi-Point DP Method" using chemical injection.

• 

  Residential foundation reinforcement-related work(8)

  We are engaged in construction using various methods, including the "SAT Column Method" and "TSC Method," which have received technical evaluation certification for column-type improvement methods, as well as pile-type ground reinforcement methods such as the "SEP Method" and "Pure Pile Method," and other techniques like "Surface Improvement Method," "Steel Pipe Pile Method," and "Soil Bag Method."

• 

  Advancement construction method(6)

  We are engaged in construction using various methods such as the "Hume pipe jacking method," which incorporates a tunneling machine shell made of CPC steel pipes and includes recoverable driving equipment necessary for tunneling; the "CMT method"; and the "SS small method" for large and medium diameter pipe jacking. Additionally, we employ the "Cobra method," which allows for construction in rock and gravel layers using small diameter jacking, and the "Bell method," which enables long-distance and curved jacking using PVC pipes.

• 

  Shaft construction method(1)

  We are conducting construction using the "PIT method," which is environmentally friendly and features no vibration and low noise, utilizing the PC1500 to PC3000 vibration-free press-in type pit construction machine.

• 

  Groundwater lowering construction method(2)

  We also carry out construction using the "Well Point Method (Vacuum Forced Drainage Method)" and the "Deep Well Method," which can also implement groundwater recharge methods (Recharge Wells).

• 

  Electric discharge crushing method(1)

  Breaks hard and solid bedrock and concrete using electric power. It produces low noise and can be used in urban areas and indoors. The breaking device can be mounted on a one-box vehicle.

• 

  Repair work(1)

  We are conducting construction using the "Zipex Method," which employs concrete modifiers that block the penetration of water and harmful substances, enhancing durability performance.

• 

  Construction examples(4)

  We are showcasing examples of various construction projects.
