Solving problems at school! Introducing "TerraTech" construction examples for settlement correction and void filling.
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 primarily offer the "TerraTech Method," which allows us to level tilted floors without stopping operations, and we provide various construction proposals tailored to our customers' concerns, from investigation to execution. ■ Nationwide responsible construction with over 5,000 completed projects Mainmark has established offices in eight locations across the country and conducts responsible construction nationwide. We serve a wide range of clients, including factories, stores, warehouses, offices, and apartments. ■ Non-disruptive floor tilt and subsidence correction method "TerraTech Method" Our main service, the "TerraTech Method," is a patented technique that injects TerraTech resin (rigid polyurethane foam resin) into concrete floors that have developed tilts, subsidence, steps, or voids due to ground subsidence or earthquakes. The expansion force of the resin levels the sunken floor and fills the voids beneath it. This technology is also registered with the Ministry of Land, Infrastructure, Transport and Tourism's "NETIS," ensuring its reliability.
