[Construction Case] Correction of sunken store floor due to consolidation settlement in a large chain store.
Implementing with sufficient attention to noise! Introducing examples of work conducted at night during business closure.
Here is an example of "settlement correction work" carried out at a large chain store in Akita Prefecture. Due to consolidation settlement, a maximum settlement of 121mm occurred. We addressed this using the Upcon method, which produces almost no noise, dust, or vibration, while paying particular attention to nighttime noise for nearby residents during construction. The work was carried out over four nights outside of business hours. We injected polyurethane resin into the floor slab and corrected all areas within the construction range, including the maximum settlement of 121mm, to within the planned values. (Correction of over 100mm) 【Case Overview】 ■ Construction Area: Approximately 1,160m2 ■ Maximum Settlement: 121mm ■ Area: Akita Prefecture ■ Construction Period: Continuous nighttime work for four days *For more details, please refer to the PDF document or feel free to contact us.
