[Construction Example] Supermarket: Subfloor Settlement Correction Work (Chiba Prefecture)
Due to the impact of the Great East Japan Earthquake, the floor inside the store sank! A case where repairs were made during the night while the store was closed.
Here is a case study of "subfloor sinking correction work" conducted at a large supermarket in Chiba Prefecture. Due to the impact of the Great East Japan Earthquake, the floor inside the store sank significantly. The Upcon method, which can be corrected during the night while the store is closed, was adopted, and our company carried out the correction. Since the store primarily handles fresh food products, we not only used plastic sheets for protection around the injection gun during construction but also enclosed the injectors to prevent resin dispersion while working. 【Case Overview】 ■ Construction Area: Approximately 2,000 m² ■ Maximum Sinking Amount: 99 mm ■ Area: Chiba Prefecture ■ Construction Period: Continuous 9 nights * To expedite the construction period, two construction plant vehicles were utilized (2011). * For more details, please refer to the PDF document or feel free to contact us.
