Teratec Construction Report: Factory

Solving your factory problems! Introducing "TerraTech" case studies for subsidence correction and void filling.

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.

[Construction Example] Bag Manufacturing Factory: Floor Slab Settlement Correction Work and Underfloor Void Filling Work

The machine's level cannot be secured, and spacers are being used. A malfunction has occurred in the machine, affecting product accuracy. This can be resolved with the up-con method.

This time, we will introduce a case study of a bag manufacturing factory in Miyagi Prefecture. Due to the impact of the Great East Japan Earthquake that occurred in March 2011, the floor sank, causing the machines to tilt and hindering production.
