The occurrence of pests is partly caused by "voids under the concrete floor." Voids under the floor, which can occur due to ground subsidence, have high humidity and little temperature variation throughout the year, making them ideal habitats and breeding grounds for pests. In the "Teratec Method," the voids below are examined with an endoscope to measure the volume of the voids. A small injection hole, smaller than a one-yen coin, is made in the floor surface with voids, and a special polyurethane resin called "Teratec Resin" is injected. The injected Teratec Resin expands within seconds, filling the voids. By filling the voids completely, it traps adult pests and eggs, eliminating their habitat and shutting off their entry routes. 【Features】 - Eliminates habitats and blocks entry routes - No use of insecticides, and no debris or dust generated - Does not interrupt operations in factories, warehouses, or stores (the construction period is just one day for an area of 200 square meters) - Accommodates construction on weekends or at night - Improves hygiene and operational efficiency by filling voids under the floor - Does not put a burden on the ground *For more details, please download the catalog or feel free to contact us.

■TerraTech Method for Suppressing Settlement of Footing Slabs The TerraTech method involves injecting a special polyurethane resin called "TerraTech" into voids that occur beneath footing slabs due to ground subsidence. By utilizing the expansion force of the resin, the voids are filled, the ground is compacted, and the footing slab is lifted. This patented method (Patent No. 4896949) addresses the concentrated loads at the edges of the footing slab caused by the formation of voids, which can accelerate the settlement of the slab and lead to issues such as wobbling. By filling the entire area beneath the footing slab with the TerraTech method, concentrated loads are alleviated, and the load is effectively transmitted to the ground. 【Features】 ◆ Installation of a single footing slab in one day ◆ The injected material is lightweight (about 1/30th the weight of mortar), significantly reducing the risk of ground subsidence due to its own weight ◆ The curing time of the injected material is quick (about 30 seconds), resulting in shorter road closure times and minimal penetration into the ground ◆ Does not use VOCs (volatile organic compounds), making it environmentally friendly and highly safe ◆ Reduces maintenance and repair costs that would otherwise need to be repeated multiple times ● For more details, please download the catalog or feel free to contact us.

When cavities occur under the floors of factories and warehouses... the vibrations and noise from the installed machinery worsen, the floor shakes every time a fork (reach) lift passes, cracks and unevenness appear on the floor, causing employees to trip, which greatly reduces work efficiency. Additionally, in the event of natural disasters such as earthquakes, the floor may collapse. 【What is the Terafil Method?】 The Terafil method is the lightest cement-based filling and embankment method available, offering a choice between permeable type "Terafil OC" and impermeable type "Terafil CC." In areas with weak ground where ground subsidence occurs, the weight of the cavity filling material or embankment material can further burden the weak ground and promote subsidence. Developed for filling and embankment in soft ground areas, Terafil possesses about ten times the strength compared to filling and embankment materials made primarily of soil, while minimizing the load during construction. The permeable type "Terafil OC" is suitable for filling and embankment materials in areas with high groundwater levels due to its low buoyancy characteristics. ▼ Features of Terafil ▼ - Lightweight and strong - Excellent permeability - Consistently high quality - Compact preform method - Compatible with subsidence correction through combined methods Toll-free number: 0120-873-835

We would like to introduce a case where problems caused by subsidence and voids in a factory were resolved by Teratech. [Problem] In a steel processing factory located in Ibaraki Prefecture, the concrete floor sank by about 3.4 cm. Although the factory had not been in operation for long, subsidence occurred, causing issues with the laser processing machine purchased for steel processing, which could no longer operate according to the specifications. For precision machines like laser processing machines, having a level floor is crucial for normal operation. [Reasons for Choosing Teratech] - Work can be carried out without stopping operations. - The work can be completed in a short time. [Feedback After Construction] "We were planning to readjust the level of the laser processing machine after this construction, but the floor correction was done so well beyond our expectations that the processing machine is now operating normally. We were very relieved that the planned budget of 1 million yen for the laser level adjustment was no longer necessary," we received words of gratitude. In addition, we also introduce resolution cases from packaging material manufacturing factories. *For more details, please refer to the external link page or feel free to contact us.

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.

We would like to introduce a case where we solved problems caused by subsidence and voids at a school using the Teratec method. 【Problem】 We received a consultation from a junior high school in Yamagata Prefecture stating, "The classroom floor is sagging, and the desks are wobbling." Upon investigation, it was confirmed that voids were present under the floors in six classrooms due to long-term ground subsidence. 【Reason for Choosing Teratec】 It was believed that the methods to address ground subsidence of concrete floors were either to redo the flooring or to apply a topping and adjust the level. However, considering the time required for moving, demolition work, and the curing period after concrete pouring, it was determined that the construction would take more than a month, making it difficult to complete during the summer vacation. Therefore, the Teratec method was adopted. 【Feedback After Construction】 By utilizing the summer vacation period to implement this method, we were able to completely eliminate the wobbling of desks and chairs. *For more details, please visit the external link page or feel free to contact us. https://teretek.jp/plus/case/school Toll-free number: 0120-873-835

We would like to introduce a case where the issues of subsidence and voids in concrete paved roads were resolved using the Teratec method. The "Teratec method" is a technique that allows for the filling of "voids" beneath concrete paved roads caused by ground subsidence and groundwater, enabling the quick correction of dangerous "differentials and bumps" in the road surface. [Issues] In the concrete paved road within a tunnel on a national highway in Shizuoka, differentials and bumps were occurring. [Reason for Choosing Teratec] Due to the short duration of the national highway maintenance and repair work, conventional methods were not feasible, so we were looking for a method that could be implemented in a short time. The Teratec method was adopted because it allows for the correction of differentials in a short construction time. [Feedback After Construction] We were able to complete the work over an area of 115m2 in 2 days (from 9 PM to 6 AM the following morning). [Case Summary] ■ Concrete paved road within a national highway tunnel - Location: Shizuoka Prefecture - Construction area: 115m2 - Construction period: 2 days (from 9 PM to 6 AM the following morning) *For more details, please refer to the external link page or feel free to contact us.
