Unevenness Correction" Correction of uneven concrete floors "TerraTech Method
We will quickly fix the "wobbling" and "unevenness" at the floor joints caused by the hollow space under the floor without damaging it!
Unevenness and bumps in the concrete floor that hinder the smooth operation of forklifts. Every time the forks pass, it rattles, causing damage to the cargo, items to fall from the forks, and requiring a reduction in speed, which significantly decreases work efficiency, doesn't it? Not only does the decline in work efficiency pose a problem, but it also presents numerous safety hazards for employees. With the "Teratec Method," we can eliminate the unevenness and bumps in the concrete floor without breaking it and without halting operations, all in a short time. Since we do not break the floor, there is almost no noise, debris, or dust generated. We offer services 24 hours a day, 365 days a year, including weekends and holidays! For adjustments to the unevenness and bumps in concrete floors in factories, warehouses, cold storage facilities, and distribution centers, please feel free to contact us.

basic information
【Concerns Due to Floor Instability】 - Small cracks have formed at the joint of the concrete floor, causing vibrations every time a forklift passes. - The joint of the concrete floor has started to crack. - Vibrations occur every time a forklift passes, leading to product defects. - There are issues with opening and closing doors. - There are issues with forklift operation. - The wear on forklift tires has increased significantly. - The maintenance costs for forklifts have risen. Until now, the mainstream method for eliminating instability and unevenness involved breaking the floor to replace or add new concrete. This method took about a week to complete, during which time the area could not be used. With the "Teratec Method," "We can correct instability and unevenness without breaking the floor and without halting operations." We drill holes smaller than a one-yen coin into the concrete floor and inject Teratec resin. The injected resin expands and spreads beneath the floor, filling voids. Further injection causes the resin's expansion force to lift the floor. The standard construction covers 200 square meters in one day. Forklifts can be operated immediately afterward.
Price information
After investigating the sinking amount and cavity volume, we will provide a design estimate. The inspection is free of charge, so please feel free to consult with us. Toll-free number: 0120-873-835.

We have published examples of the construction work for the sinking correction project.
We have newly published a case study on our service site for the Teratec method. This is a case of settlement correction work carried out at an electronics retail store in Shiga Prefecture. There were concerns about the sagging of the store floor due to ground subsidence, and we were consulted by the company. We understand that our Teratec method was chosen because it allows for construction without interrupting daily operations. Additionally, the positive feedback from a previous project was also a key point. Our company has extensive experience in settlement measures and void filling work while maintaining daily operations for stores and factories. With eight offices nationwide, we are ready to assist you, so please feel free to contact us if you are facing issues with ground subsidence or voids under your floors. ■ Case Study (Teratec Method Service Site): https://teretek.jp/repo/r181

We have published examples of construction work for cavity filling (BCP measures).
We have newly published construction case studies on the service site for the Teratec method. This is a case of filling voids beneath the floor slab conducted near an automatic rack warehouse in Toyama Prefecture. There were concerns about subsidence of the surrounding roads and building floors due to ground subsidence following the Noto Peninsula earthquake, and we received inquiries from clients regarding this issue. We have been informed that the key factor for choosing our Teratec method was its ability to perform "short-term construction without stopping truck traffic." Additionally, the effectiveness of compacting loosened ground has also been highly evaluated. Our company has extensive experience in subsidence countermeasures and void filling work while maintaining daily operations in logistics warehouses and factories. With eight branches nationwide, we are equipped to respond to issues related to ground subsidence and voids beneath floors, so please feel free to contact us if you have any concerns. ■ Construction case studies (Teratec method service site): https://teretek.jp/repo/r180
