We would like to introduce a case where problems caused by subsidence and voids in a factory were resolved by Teratech. [Problem] In a steel processing factory located in Ibaraki Prefecture, the concrete floor sank by about 3.4 cm. Although the factory had not been in operation for long, subsidence occurred, causing issues with the laser processing machine purchased for steel processing, which could no longer operate according to the specifications. For precision machines like laser processing machines, having a level floor is crucial for normal operation. [Reasons for Choosing Teratech] - Work can be carried out without stopping operations. - The work can be completed in a short time. [Feedback After Construction] "We were planning to readjust the level of the laser processing machine after this construction, but the floor correction was done so well beyond our expectations that the processing machine is now operating normally. We were very relieved that the planned budget of 1 million yen for the laser level adjustment was no longer necessary," we received words of gratitude. In addition, we also introduce resolution cases from packaging material manufacturing factories. *For more details, please refer to the external link page or feel free to contact us.

The Teratech method quickly corrects the tilting, sagging, distortion, and unevenness of floor slabs in factories, warehouses, stores, and shopping centers caused by ground subsidence by injecting a special urethane resin called "Teratech resin." ◆ Teratech Method * A cavity survey under the floor is conducted in advance. 1. Measure the tilt of the floor. 2. Drill holes with a diameter of 6 millimeters, smaller than a one-yen coin, at the correction points. 3. Use proprietary equipment to inject resin under the floor slab. 4. The injected resin begins to expand instantly. This expansion force compacts and strengthens the ground while pushing the floor upward. 5. Correct the floor while measuring its movement in millimeters. 【Features】 ■ Lifts from underneath the floor, so no damage to the floor. ■ Short construction period; can level an area of 200 square meters in one day. ■ Cost-effective compared to demolition and restoration work. ■ No demolition work means it is quiet and produces no waste. ■ Does not use water, so it does not dirty products or machinery. By addressing floor subsidence, tilting, and cavity filling, we can ensure the safety of workers and customers, improve work efficiency, and enhance the internal environment, leading to better business performance.
