Significant damage from the Great East Japan Earthquake! Introducing a case of subsidence correction with a maximum subsidence of 112mm.
Here is an example of "subfloor sinking correction work" carried out at a large pachinko parlor located in Miyagi Prefecture. The large pachinko parlor suffered significant damage due to the Great East Japan Earthquake. Extensive renovation work was conducted to reopen for business as soon as possible. Sinking also occurred in the store's floor, and the Upcon method, which allows for quick corrections, was adopted. Our company implemented the floor sinking correction. We injected urethane resin under the subfloor and corrected all areas within the construction scope, including a section that had sunk by a maximum of 112mm, to within the planned values. 【Case Overview】 ■ Construction Area: Approximately 230m2 ■ Maximum Sinking: 112mm ■ Area: Miyagi Prefecture ■ Construction Period: 1 day (2011) *For more details, please refer to the PDF document or feel free to contact us.
