■ The machine cannot be leveled. ■ The machine is tilted and vibrating. ■ Malfunctions are occurring in the machine, leading to an increase in defective products. ■ Gaps have formed in the floor, walls, and ceiling. ■ Cracks have appeared in the floor. The "Upcon Method" solves problems caused by floor tilting and sagging due to earthquakes or ground subsidence, as well as voids and gaps that have formed beneath the floor, using polyurethane resin for quick repairs. 【What is the Upcon Method?】 Small holes with a diameter of 16mm are drilled into the existing concrete floor where subsidence has occurred. While continuously monitoring the level in millimeter increments, polyurethane resin is injected. The resin injected beneath the floor expands under pressure in a short time, compacting and strengthening the ground, improving bearing capacity, and pushing the concrete back to a level position. The final strength of the resin is achieved in about 60 minutes. Even if voids have formed beneath the floor, the same method is used to fill those voids. Since the existing concrete floor is repaired without demolition, the construction period is significantly reduced compared to conventional methods. The polyurethane can lift the floor with a foaming pressure of up to 10 tons per square meter, eliminating the need to move heavy equipment or materials. The deformation of the floor is corrected without stopping the production line.

In a factory where a machine weighing approximately 26 tons is placed, the floor began to vibrate after the earthquake. To confirm the situation before the installation of the machine, core drilling was performed at several locations. As a result, it was confirmed that there was a gap of up to approximately 180mm beneath the concrete. By carrying out gap filling work, we were able to restore the original performance of the concrete floor and suppress the floor vibrations. Additionally, we also conducted floor subsidence correction work at a factory of T Industry located in Miyagi Prefecture. 【Case Study】 <Floor Vibration Suppression Work at T Printing Company Factory in Miyagi Prefecture> ■ Construction: (Phase 1) July 2011, (Phase 2) October 2011 ■ Maximum Gap Size: Approximately 180mm ■ Total Construction Area: Approximately 160m2 ■ Actual Working Days: 1.5 days *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of floor sinking correction work and subfloor void filling work carried out at a bag manufacturing factory located in Miyagi Prefecture. The neatly arranged bag-making machines were tilted due to floor sinking, which hindered production. As a temporary measure, legs (for height adjustment) were installed under the machines to level them, allowing work to continue. Consequently, we received a request for correction from the company, as we can quickly make adjustments without removing the machines, and we proceeded with the work. In addition to the floor sinking, voids were also observed under the floor, so we carried out the filling work as well. [Case Study] ■ Construction Area: Approximately 730m² ■ Maximum Sinking Amount: Approximately 110mm ■ Construction Period: 3 days *For more details, please refer to the PDF document or feel free to contact us.
