[TeraTech Construction Report] Asphalt Paved Road
TerraTech method
Solving problems with asphalt paved roads! Introducing examples of void filling and unevenness correction.
We would like to introduce a case where the Teratec method solved issues related to subsidence and voids in asphalt paved roads. 【Issues】 As a result of conducting a void investigation on aging roads in Tokyo, abnormal values indicating voids were confirmed at nine locations. 【Reason for Choosing Teratec】 In order to carry out the construction, it was necessary to meet the following conditions, all of which were satisfied by Teratec: - Use of lightweight materials to suppress re-subsidence - Minimizing traffic restrictions as much as possible - Material strength exceeding that of fluidized treated soil (300KN/m2) 【Feedback After Construction】 Multiple locations could be filled in one day, and the time for traffic restrictions was minimized, allowing for efficient progress of the work. 【Construction Details】 ■ Drilled confirmation holes to assess the void situation ■ After drilling injection holes, inserted injection pipes and injected Teratec resin ■ The injected resin expanded to fill the voids ■ The expansion force during the reaction compacted the surrounding loosened ground *For more details, please refer to the external link page or feel free to contact us.

basic information
**Advantages of Teratech** - Easy to move the plant, allowing multiple installations in one day - Mitigates subsidence risk within a few hours - Fast curing time for resin, with short regulation time (work can be done with one-sided regulation) - The resin is lightweight, reducing the risk of re-subsidence due to its own weight - Minimal construction by-products and waste generated - The compressive strength of Teratech resin is approximately 430 kN/m², stronger than fluidized treated soil (300 kN/m²) *For more details, please refer to the external link page or feel free to contact us.

Company information
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"
