アップコン List of Products and Services

■The cargo in the warehouse is not stacked straight. ■There are uneven surfaces that hinder the movement of forklifts. ■The equipment, such as racks, is tilted. ■Abnormal operation is observed in the automatic racks. ■The transport robot has stopped. ■The level of the machinery cannot be secured. The patented unique method called [Upcon Method] uses polyurethane resin to resolve issues caused by floor tilting, unevenness, and sagging due to earthquakes or ground subsidence, as well as voids formed under the floor, with corrections possible in as little as one day. [What is the Upcon Method?] By injecting polyurethane resin into existing concrete floors that have subsided, it compresses and strengthens the ground with pressure that expands in a short time while pushing up the concrete floor for correction. Since it corrects without demolishing the existing concrete floor, it significantly reduces construction time. The polyurethane can lift the floor with an expansion pressure of up to 10 tons per square meter, eliminating the need to move heavy equipment or products. Therefore, corrections can be made without stopping the operations of factories or warehouses. ▼We will exhibit at the [International Logistics Comprehensive Exhibition 2024]. Date: September 10 (Tuesday) to 13 (Friday), 2024 Venue: Tokyo Big Sight, East Exhibition Hall Booth Number: 7-808

We would like to introduce a case of "earthquake recovery construction" and "floor subsidence correction work" carried out at a toy retail store and an electronics retail store in Fukushima Prefecture. Due to the impact of the Great East Japan Earthquake, the floor inside the toy retail store sank significantly. As a result of the floor subsidence, gaps were observed between the floor and walls, as well as between the walls and ceiling. Therefore, an up-con method that can be corrected during the night while the store is closed was adopted, and our company carried out the correction work. Additionally, since there were voids under the floor, we also implemented void filling work by injecting polyurethane resin into the gaps. 【Case Overview】 ■ Construction Area: Approximately 2,300m2 ■ Maximum Subsidence: 144mm ■ Area: Fukushima Prefecture ■ Construction Period: Continuous 11 nights (2012) *For more details, please refer to the PDF document or feel free to contact us.
