Quickly correct the factory floor's slope and the gaps under the floor with rigid polyurethane foam resin!

Quickly correct the factory floor's slope and the gaps under the floor with rigid polyurethane foam resin!

Correct the floor tilt caused by earthquakes or ground subsidence without stopping operations and in a short time! No need to move machines or equipment! Also suppress any concerning vibrations from the machines!

■ The level of the machine cannot be secured. ■ 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" uses polyurethane resin to quickly correct issues caused by tilting or sagging of the floor, as well as voids or gaps that have formed beneath the floor due to earthquakes or ground subsidence. 【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 reinforcing 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. Additionally, if voids have formed beneath the floor, they are filled using the same method. By correcting the existing concrete floor 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 loads. The deformation of the floor is corrected without stopping the production line.

[Construction Case] Fukushima Prefecture, Soma Port Port Maintenance Management Work (Quay Restoration)

[Construction Case] Fukushima Prefecture, Soma Port Port Maintenance Management Work (Quay Restoration)

Due to ground subsidence at the harbor's quay, there are steps and depressions in the concrete pavement, resulting in the loss of water gradient and the formation of puddles. This issue is resolved using the Upcon method.

The Upcon method, which allows for modifications without breaking existing concrete pavement slabs and within a short construction period, has been widely adopted in public works such as roads and airports as a maintenance and repair method. This time, we will introduce a construction site for correcting the sinking of concrete pavement slabs and filling voids at a quay in a port. The quay at Soma Port in Fukushima Prefecture, where cargo loading and unloading occurs frequently, has experienced issues due to ground subsidence, resulting in steps and sinking in the concrete pavement slabs, eliminating the water slope and causing puddles. This has hindered cargo operations. The Upcon method was chosen because it has no environmental impact compared to other methods and can correct the existing slabs without removal in a short period. [Site Information] Soma Port Port Maintenance Management Work (Quay Restoration) Construction Area: Approximately 285 square meters Maximum Subsidence: 97mm Construction Period: 4 days For detailed information on the construction process, please refer to the PDF download below.

[Construction Case] Filling Work for Void Under Concrete Pavement Slabs of Kanmon Tunnel

[Construction Case] Filling Work for Void Under Concrete Pavement Slabs of Kanmon Tunnel

Fiscal Year 2013 Shimonoseki Area Preservation Work (Kanmon Tunnel Concrete Pavement Slab Void Filling Work)

The Kanmon Tunnel connecting Fukuoka Prefecture and Yamaguchi Prefecture. When large vehicles pass through the toll booth near the tunnel entrance and exit, vibrations were occurring in the nearby residential area. An investigation conducted by FWD revealed the presence of voids believed to be the cause of the vibrations directly beneath the concrete pavement slabs. The Upcon method is a technique that involves injecting rigid polyurethane resin beneath the concrete pavement slabs. The filling and compaction effects of the polyurethane can resolve the loosening and voids in the subgrade that cause vibrations. The Upcon method was adopted with the aim of suppressing slab vibrations by improving the environment of the upper subgrade. 【Site Information】 Fukuoka Prefecture - Yamaguchi Prefecture / Kanmon Tunnel Total construction area: Approximately 200 square meters Construction period: 2 nights

Emergency restoration method "Dantan": A new technique by the sinking correction expert Upcon.

Emergency restoration method "Dantan": A new technique by the sinking correction expert Upcon.

Quickly restore road unevenness and depressions during an earthquake with polyurethane resin, enabling swift vehicle passage. Contributing to the establishment of emergency transportation routes!

The new method "Emergency Restoration Method Dantan" developed by Upcon involves spraying high-strength polyurethane resin onto road unevenness caused by disasters during earthquakes to create a slope, enabling temporary vehicle passage for the early establishment of emergency transportation routes. A truck equipped with all necessary materials rushes to the site and sprays a two-component polyurethane resin onto the created unevenness. The high-strength polyurethane resin has the property of hardening immediately after spraying, allowing for vehicle passage within 15 minutes after the slope is created. Additionally, it can be used to repair not only unevenness but also depressions and subsidence. Features of the Emergency Restoration Method Dantan: - Ability to create slopes tailored to the shape of the disaster-affected site - Resolution of unevenness in about one hour, allowing immediate vehicle passage Furthermore, it has a proven track record in correcting tilts and unevenness of concrete floors and pavement slabs caused by earthquakes or ground subsidence, as well as filling voids. [Exhibiting at EE Tohoku '23] We will be exhibiting at the comprehensive exhibition of new technologies, EE Tohoku '23. At our booth, we will conduct demonstrations using polyurethane resin. Location: Yume Messe Miyagi Dates: June 7 (Wed) - 8 (Thu) Booth No: West Hall Exhibition B-708

"Concrete slab sinking correction method" contributes to the longevity of social infrastructure.

"Concrete slab sinking correction method" contributes to the longevity of social infrastructure.

Using high-strength urethane resin, we will correct the deformations such as subsidence, steps, flapping, gaps, and cavities that have occurred in the concrete slab, without excavation and within a short construction period.

The Upcon concrete slab settlement correction method (KT-080008-A, NETIS registration period ended in October 2014) quickly resolves issues such as settlement, unevenness, flapping, gaps, and voids that occur in concrete pavement slabs commonly used in highways and other areas, using specially developed high-strength polyurethane resin. It achieves a short construction period by utilizing a highly mobile plant without breaking the existing pavement slabs or requiring excavation work. This minimizes the period of service suspension and has a proven track record as a planned and efficient method for maintaining social infrastructure. This technology is also adopted not only for highways but also for repair work in ports and airport aprons, as well as disaster recovery work. Upcon will exhibit at the "Highway Techno Fair 2023," where cutting-edge technologies supporting highways will be showcased. Date: November 9 (Thursday) and 10 (Friday), 2023, from 10:00 to 17:00 Location: Tokyo Big Sight, West Hall 3 Exhibition Booth No: A-04 On that day, there will also be a demonstration of settlement correction using polyurethane resin. We invite you to take this opportunity to see it. We look forward to your visit.

[Construction Case] Short-term Correction: Certain Food Warehouse Void Filling Work

[Construction Case] Short-term Correction: Certain Food Warehouse Void Filling Work

Upcon construction method using rigid polyurethane foam! Introducing a case where a cavity was corrected in three days.

We would like to introduce a case of "void filling work" conducted at a certain food warehouse in Kanagawa Prefecture. Using the Upcon method, which allows for the filling of voids that developed under the floor with polyurethane resin in a short period, we corrected a maximum void of 270mm (with a construction area of approximately 171m2) in just three days. After the resin filling, we checked the filling condition with a CCD camera and used non-shrink mortar to seal the injection holes. 【Case Overview】 ■ Construction Area: Approximately 171m2 ■ Maximum Void Size: 270mm ■ Location: A certain food warehouse in Kanagawa Prefecture ■ Construction Period: 3 days *For more details, please refer to the PDF document or feel free to contact us.
