Zero downtime for filling voids under the floor! The Teratec method reduces machine vibrations.

■What is the Teratech Method? It is a patented method that involves drilling small injection holes with a diameter of 6 mm and injecting hard polyurethane "Teratech resin" under the floor. The expansion force of the resin fills the voids beneath the floor and levels the sunken floor. 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 the customer's operations. *Depending on the structure of the floor and the condition of the subsidence, construction may be done with a 6 mm hole. ■Teratech Method has vibration suppression effects Resin is injected under the floor where machinery is installed or around it. The expanding resin thoroughly fills the voids that have formed beneath the machinery. The resin has the ability to absorb vibrations, thereby suppressing the vibrations of the machinery. Additionally, by directly injecting resin into the ground, which easily transmits vibrations, the ground bearing capacity can be strengthened, preventing vibrations. ■Investigation conducted before construction - Void volume survey Several holes of approximately 10 mm are drilled into the floor slab, and an endoscope is used to measure the thickness of the floor slab and the volume of voids beneath it. - Subsidence survey Surveying equipment is used to measure the height of the floor slab, quantifying the amount of subsidence and deflection of the floor. - Vibration survey (optional) A small sensor is installed to quantify vibrations. This can be used to predict and confirm the vibration suppression effects.

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.

【"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

The continuously sinking stepping board can be stabilized against subsidence with cavity filling.

The urethane resin injection method was introduced to Japan in 2001, evolved uniquely within the country, and obtained a patent in January 2016. ● TerraTech Method Flow for Filling Cavities Under Roads 1. Drill a hole with a diameter of 6 mm, smaller than a one-yen coin, at the target location. 2. Use specialized equipment to inject resin under the road. 3. The injected resin begins to expand instantly. This expansion compresses and strengthens the ground, pushing up the sunken slab. 4. Confirmation of the filling is conducted through confirmation holes, etc. * Injection work: All equipment is mounted on one truck. ● Road Surface Restoration 1. Restore the injection and confirmation holes with cold mix materials, etc. ● Features of the TerraTech Method for Filling Cavities Under Roads 1. No excavation work is required, and since the injection hole is φ16mm, there are no remnants of construction and no step formation occurs. 2. The standard working time per location is about 50 minutes, minimizing traffic regulation time. 3. 80% of the final strength of the resin is achieved in 10 minutes, allowing for immediate safety assurance.

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.

Lightweight filling and embankment method "Terrafill" designed for weak ground areas.

●Light and Strong● Terafil is the lightest among cement-based materials, possessing about 10 times the strength of filling and embankment materials primarily made of soil. This allows for construction that maintains a certain strength while minimizing the load on weak ground. ●Excellent Permeability (Terafil OC)● With permeability close to that of fine sand, it minimizes the impact of buoyancy after hardening even when poured in areas with high groundwater levels, and does not significantly alter the flow of groundwater after pouring. In addition to the permeable type "Terafil OC," the impermeable type "Terafil CC" can also be manufactured and poured. ●Stable High Quality● Stable foam generation, mixing just before pouring using the pre-foam method, and thorough construction management enable the production and pouring of low-density, stable lightweight filling and embankment materials. ●Compact Pre-Foam Method● The pre-foam method of construction minimizes plant size. There is no need for silo installation, which shortens the construction period required for plant setup. *For more details, please download the PDF or feel free to contact us.

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.

We will quickly fix the "wobbling" and "unevenness" at the floor joints caused by the hollow space under the floor without damaging it!

【Concerns Due to Floor Instability】 - Small cracks have formed at the joint of the concrete floor, causing vibrations every time a forklift passes. - The joint of the concrete floor has started to crack. - Vibrations occur every time a forklift passes, leading to product defects. - There are issues with opening and closing doors. - There are issues with forklift operation. - The wear on forklift tires has increased significantly. - The maintenance costs for forklifts have risen. Until now, the mainstream method for eliminating instability and unevenness involved breaking the floor to replace or add new concrete. This method took about a week to complete, during which time the area could not be used. With the "Teratec Method," "We can correct instability and unevenness without breaking the floor and without halting operations." We drill holes smaller than a one-yen coin into the concrete floor and inject Teratec resin. The injected resin expands and spreads beneath the floor, filling voids. Further injection causes the resin's expansion force to lift the floor. The standard construction covers 200 square meters in one day. Forklifts can be operated immediately afterward.
