We will correct the floor tilt and subsidence without stopping operations! Introducing examples of the "Terra Tech Method" for correcting subsided concrete floors!

Our company conducts the "TerraTech Method," a sinking correction technique that adjusts floor tilts, subsidence, steps, and voids in buildings such as factories, warehouses, stores, and schools, where it is difficult to halt operations, without breaking the existing floor. The "TerraTech Method" involves injecting a special urethane resin under the concrete slab floor, which levels the floor using its expansion force. Compared to traditional concrete replacement methods, the construction period is about 1/10 of the time, and there is no need to remove goods, machinery, or install large plants. We are offering free materials that introduce examples of sinking correction work carried out using the "TerraTech Method." The materials include detailed information about the situation before construction and the reasons for inquiries. Please feel free to download and review them.

Solving your store's problems! Introducing "TerraTech" case studies for settlement correction and void filling.

We would like to introduce a case where we solved problems caused by subsidence and voids at a store using the Teratech method. [Problem] A void was found under the concrete floor of a supermarket in Saitama Prefecture, just one month before its opening. It was also discovered that there was a 34mm height difference at the joints of the concrete floor. [Reason for Choosing Teratech] Due to the limited time before the opening, we were requested to address the issue using our polyurethane injection method. [Feedback After Construction] We performed void filling under the floor and correction of the floor height difference using the Teratech method. The adjustments were made to the millimeter level, resolving the height difference at the floor joints. Additionally, we also have examples of height difference correction work related to the renovation of a large supermarket in the Hokuriku region. [Case Overview] ■ Supermarket - Work performed: Void filling under the floor and height difference correction - Date of work: October 2016 - Location: Saitama Prefecture - Work area: 97m² - Height difference correction: 34mm *For more details, please refer to the external link page or feel free to contact us.

Short construction period! No damage to the floor! No interruption to operations! Available 24/7 throughout Japan.

"I replaced it six months ago. If I had known about this method earlier." This is a voice from our customers that we hear at exhibitions and other events. 【What is the Teratech Method?】 Unlike traditional methods of replacement or resurfacing, this method restores floor slopes, subsidence, and unevenness to a level surface without breaking the floor and without stopping operations. It is a patented method that injects Teratech resin beneath concrete floors (roads) to fill voids under the floor with its expanding force, bringing the sunken floor back to level. Since it uses injection holes smaller than a one-yen coin (6mm) to inject expanding resin without breaking the floor, there is no need to remove goods or machinery. This means there are no additional costs for moving items, temporary storage during construction, or disposal of industrial waste, aside from the construction costs. 【Main Features】 1: Can be constructed without stopping operations 2: Short construction period (150 to 200 square meters in about 8 hours) 3: No need to move goods, racks, or machinery since the floor is not broken 4: Normal use is possible immediately after construction For more details, please view the catalog from the "PDF Download" section.

We will quickly correct dangerous floor level differences in warehouses, factories, and stores without damaging the floor and without stopping operations. We provide services nationwide in Japan, 365 days a year.

The unevenness of concrete floors in factories, warehouses, and stores can hinder the smooth operation of forklifts, carts, and hand trucks, potentially leading to decreased work efficiency and compromising employee safety. With the "Teratec Method," we can correct these "unevenness" issues in a short time without breaking the floor and without stopping operations. **Features of the Teratec Method:** For concrete floors with issues such as tilting and sinking, we drill holes smaller than a one-yen coin and inject a special urethane resin called "Teratec Resin." The injected resin expands and spreads beneath the floor, filling voids (gaps). By injecting more resin, the expansion force of the resin lifts the floor back up to level. The resin can withstand a load of at least 19 tons per square meter. After the work is completed, it is possible to operate forklifts immediately. We can carry out the work on holidays, during year-end and New Year’s, and at night. We perform the work without breaking the floor and without interrupting regular operations.

Tilt and unevenness of the floor due to ground subsidence, and machine vibrations caused by hollowing. It is recommended to conduct an investigation to accurately understand the current situation.

Cracks and unevenness in the floor, tilting and sagging of the floor, and vibrations from machinery. Have you been neglecting these issues even though you are aware of them? Before they affect your operations, Mainmark visualizes hidden floor problems through three investigations. ■ Three Investigations to Visualize Floor Issues 【Void Measurement Survey】 We drill several holes of about 10 mm in the concrete floor and use an endoscope to measure the thickness of the concrete floor and the volume of voids beneath it. In addition to understanding the current situation, we perform measurements necessary for construction planning, such as calculating the amount of resin to be used. 【Level (Settlement) Survey】 Using surveying equipment, we measure the height of the concrete floor and quantify the amount of settlement and sagging. The measured values are used to set target values for corrections and to create construction plans. 【Vibration Survey】 We install high-sensitivity vibration sensors on the floor in areas of concern and measure minute vibrations. This allows us to predict the vibration reduction effects of void filling and understand the vibration reduction effects after construction. If the survey results show no issues with voids or settlement, you can continue to use the floor with peace of mind. If any problems are found, we will provide suggestions for improvements. We recommend starting with a survey to understand the current situation. Toll-Free Number: 0120-873-835

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos."
