We solve problems such as ground improvement and ground strengthening under buildings, mainly through settlement correction and void filling work using the Terra Tech method! We have surpassed 4,500 construction achievements.

■Various Experts in Different Fields Our company has a range of experts, including first-class architects with extensive experience, specializing in architecture, civil engineering, ground conditions, liquefaction, and structural vibrations. We propose construction methods tailored to your needs from a wide variety of materials. If it is difficult to resolve an issue with a single method due to the condition of the building or your concerns, we suggest a combination of methods for the construction. ■Appropriate Investigation Costs Before carrying out construction, we conduct an investigation of the site conditions and propose methods that address the issues you wish to resolve. Investigation fee: Basic fee of 50,000 yen (excluding tax) + actual transportation costs *Additional costs may apply depending on the location and conditions of the site. [Void Volume Investigation] We drill several holes with a diameter of 16 mm in the floor slab and use an endoscope to measure the thickness of the floor slab and the volume of voids beneath it. In addition to understanding the current situation, we perform measurements necessary for the construction plan, such as calculating the amount of resin to be used. [Settlement (Level) Investigation] Using surveying equipment, we measure the height of the floor slab and quantify the amount of settlement and deflection of the floor. The measured values are used to set target values for corrections and to create the construction plan. Please feel free to contact us. Toll-free number: 0120-873-835

Correcting floor subsidence caused by ground subsidence without stopping operations. "Subsidence correction and void filling" without dismantling the floor.

The floor has tilted due to ground subsidence and the weight of machines and cargo! The shelves are slanted! If this situation is left as it is, items on the shelves may fall, and the safety devices of automated transport racks may activate, causing them to stop working, leading to decreased work efficiency and compromised safety. ○ Adjust the machine's level with adjusters ○ Raise the shelves Are you making such temporary adjustments? Teratec method will resolve these concerns. With traditional methods like replacing or adding to the floor, the area cannot be used during the construction period, necessitating the halt of operations for moving cargo and machines. The costs of construction and relocation, as well as the significant business losses from stopping operations, were likely substantial. The Teratec method "corrects floor tilting and subsidence without breaking the floor and without stopping operations." If you are troubled by tilting or subsidence of concrete floors, please feel free to contact us. Our sales offices are located in Sapporo, Sendai, Tokyo, Nagoya, Osaka, and Fukuoka. We have one 3-ton construction vehicle. We propose a method for correcting floor tilting that does not burden the environment, does not involve demolition work, and does not stop operations.

We will quickly correct dangerous floor level differences in warehouses, factories, and stores without damaging the floor and without stopping operations. We provide services nationwide in Japan, 365 days a year.

【"Concerns about Floor Unevenness"】 ○ There are uneven spots on the floor, making it difficult for carts to move smoothly. ○ Employees have tripped on the uneven floor and gotten injured. ○ There is a loud noise every time a forklift passes through. ○ Work efficiency has decreased due to the uneven floor. Until now, the mainstream method was to either replace the concrete or add more to it. However, breaking the floor and replacing it with new concrete means that the area cannot be used for about a week until it dries and is ready for use. With the Teratec method, you can correct the unevenness without stopping daily operations. Please feel free to contact us. Toll-free number: 0120-873-835

Tilt and unevenness of the floor due to ground subsidence, and machine vibrations caused by hollowing. It is recommended to conduct an investigation to accurately understand the current situation.

■Support After Investigation If any hazards are found on the floor, experts in architecture and civil engineering, including first-class architects, will select the most suitable construction method from various options and provide improvement proposals. If no issues are found, you can continue to use the space with peace of mind. We also offer regular inspections, so please feel free to consult us. 【TerraTech Method】 This patented method involves drilling small injection holes of 6mm in diameter and injecting a hard polyurethane resin called "TerraTech" under the floor. The expansion force of the resin fills any voids beneath the floor and levels any sunken areas. There is no need to dismantle or remove the floor, and machinery or equipment does not need to be moved, allowing construction to proceed without interrupting your business operations. By filling the voids, vibration suppression effects can also be expected. *Please note that depending on the structure of the floor and the condition of the sinking, construction may be done using 16mm holes. Please feel free to contact us. Toll-free number: 0120-873-835

Correcting the slope, subsidence, and unevenness of the concrete floor without stopping. No need to move machinery. Available for surveys and construction 24 hours a day, 365 days a year across Japan!

The floor tilted due to ground subsidence and the weight of the cargo. The shelves became slanted. If left as is, the items on the shelves may fall, the safety devices of the automatic transport racks may activate and stop functioning, leading not only to decreased work efficiency but also compromising safety. Until now, adjustments to the machine's level have been made using adjusters, or shelves have been raised as a temporary measure. "Teratec" will resolve that concern. With traditional floor replacement or reinforcement, business operations must be halted during the construction period. The construction costs are significant, and the loss of sales can be substantial, putting pressure on management. With the "Teratec Method," you can correct floor irregularities, tilting, and subsidence without stopping operations. If you are in charge of a factory, warehouse, store, or shopping center troubled by floor issues, please do not hesitate to contact us.
