"Subsidance Correction" - Watch the "TerraTech Method" in a video.

Correcting floor subsidence caused by ground subsidence without stopping operations. "Subsidence correction and void filling" without dismantling the floor.

The "Teratech Method" is a construction technique that corrects the tilt, subsidence, and unevenness of concrete floors in factories, warehouses, stores, and shopping centers by injecting a special urethane resin called "Teratech Resin," without damaging the floor or halting operations. **Features of the Teratech Method:** - Injection holes smaller than a one-yen coin, with a diameter of 6 mm. There is no need to break the floor. - Specialized technicians perform corrections while measuring in millimeters. - Minimum load-bearing capacity of 19 tons per square meter. - Weighs approximately 10 kg per cubic meter, making it lightweight. *This is 1/20th the weight of concrete. - Short curing time of about 30 minutes, allowing large trucks to pass immediately after construction. - Standard daily construction area is 200 square meters (this may vary depending on construction conditions). Available nationwide in Japan. Construction achievements: Over 300 cases annually from Hokkaido to Okinawa. Total construction area: Over 1,177,000 square meters. We can handle projects ranging from 30 square meters to several thousand square meters for factories, warehouses, shopping centers, and more.

Settlement Correction and Void Filling: TerraTech Method Case Study Collection Giveaway

Over 4,500 construction projects! With the extension of the lifespan of structures being considered now, the number of projects in factories, warehouses, and stores is rapidly increasing!

The Teratech method quickly corrects the tilting, sagging, distortion, and unevenness of floor slabs in factories, warehouses, stores, and shopping centers caused by ground subsidence by injecting a special urethane resin called "Teratech resin." ◆ Teratech Method * A cavity survey under the floor is conducted in advance. 1. Measure the tilt of the floor. 2. Drill holes with a diameter of 6 millimeters, smaller than a one-yen coin, at the correction points. 3. Use proprietary equipment to inject resin under the floor slab. 4. The injected resin begins to expand instantly. This expansion force compacts and strengthens the ground while pushing the floor upward. 5. Correct the floor while measuring its movement in millimeters. 【Features】 ■ Lifts from underneath the floor, so no damage to the floor. ■ Short construction period; can level an area of 200 square meters in one day. ■ Cost-effective compared to demolition and restoration work. ■ No demolition work means it is quiet and produces no waste. ■ Does not use water, so it does not dirty products or machinery. By addressing floor subsidence, tilting, and cavity filling, we can ensure the safety of workers and customers, improve work efficiency, and enhance the internal environment, leading to better business performance. Please feel free to contact us. Toll-free number: 0120-873-835

The first step in warehouse automation is the "Terra Tech Method" from the level of the floor.

Currently, with the advancement of delivery management and warehouse automation utilizing AI and big data, the levelness of the facility's floor is an important theme for the introduction of automation equipment.

If the floor is not level... ☑ The installation of high-rise racks will require liner support, causing anxiety! ☑ There is a possibility that high-pick operators may fall, making it unusable! ☑ There may be obstacles to the operation of AGVs (automated guided vehicles)! ☑ High stacking of pallets and nestainers may become tilted and impossible! The "TerraTech Method" levels the floor's tilt and subsidence in a short construction period. ◆ What is the TerraTech Method? Is your warehouse's concrete floor tilted or sunken? The TerraTech Method involves injecting TerraTech resin beneath the concrete floor, using its expansion force to return the sunken floor to level and fill any voids underneath. This patented method corrects the "tilt," "sinking," "steps," and "deflection" of the concrete floor without damaging it, and does so in a short period. Please feel free to contact us.

[Construction Case] Vibration Suppression in Precision Parts Manufacturing Factory - Void Filling Work

"The earthen floor is sagging, causing the machine to vibrate." "The vibration of the machine affects product accuracy." Quickly resolved with the up-con method.

This time, we will introduce a case study of a precision parts manufacturing factory in Saitama Prefecture. Due to ground subsidence, cracks and deflection occurred in the concrete floor, causing vibrations in the machinery. To prevent the impact of vibrations on product accuracy, we carried out subsidence correction work to alleviate deflection and void filling work under the concrete floor. The Upcon method was adopted because it allows for construction without moving the machinery and without stopping operations. 【Site Information】 Saitama Prefecture / Precision Parts Manufacturing Factory Construction Area: 287 square meters Maximum Subsidence: 44 mm Maximum Void Volume: 50 mm Construction Period: 3 days You can view detailed construction information in the PDF download below.

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

Correcting floor tilts caused by earthquakes and ground subsidence without stopping operations and in a short period! No need to move machines or equipment! Also suppressing any concerning vibrations from the machines!

■ 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.

Road Concrete Pavement Slab Settlement Correction Method Achieves Early Lifting of Traffic Restrictions

We will correct the irregularities such as steps and flapping that have occurred in the concrete pavement slabs using specially developed high-strength polyurethane resin, without excavation and within a short construction period.

Using a specially developed high-strength polyurethane resin, we will correct the deformation such as steps and fluttering that occur in concrete pavement slabs commonly used on highways, as well as fill the gaps and voids that have developed under bridge deck slabs, all without breaking the existing concrete pavement and within a short construction period. Injecting polyurethane resin will also improve the loosening of the subgrade. Additionally, it enables the lifting of joints with polyurethane resin along with the bearing slab, fundamentally resolving the issue of correcting the step at the joint, which traditionally required excavation and long-term continuous restrictions or road closures.
