Company information
We create reliable technology with forward-thinking ideas, addressing structural inclinations of buildings and the challenges of the underlying ground while maintaining our customers' operations, thereby protecting lives and businesses.
The main business activities of Mainmark involve "returning tilted floors and buildings to a level state" and "preventing existing floors and buildings from tilting." 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. Patent No. 4896949 "Method for Correcting Sunken Floors" NETIS Registration No. "QS-080007"
