We have newly published a case study on our service site for the Teratec method. This is a case of settlement correction work carried out at an electronics retail store in Shiga Prefecture. There were concerns about the sagging of the store floor due to ground subsidence, and we were consulted by the company. We understand that our Teratec method was chosen because it allows for construction without interrupting daily operations. Additionally, the positive feedback from a previous project was also a key point. Our company has extensive experience in settlement measures and void filling work while maintaining daily operations for stores and factories. With eight offices nationwide, we are ready to assist you, so please feel free to contact us if you are facing issues with ground subsidence or voids under your floors. ■ Case Study (Teratec Method Service Site): https://teretek.jp/repo/r181

We have newly published construction case studies on the service site for the Teratec method. This is a case of filling voids beneath the floor slab conducted near an automatic rack warehouse in Toyama Prefecture. There were concerns about subsidence of the surrounding roads and building floors due to ground subsidence following the Noto Peninsula earthquake, and we received inquiries from clients regarding this issue. We have been informed that the key factor for choosing our Teratec method was its ability to perform "short-term construction without stopping truck traffic." Additionally, the effectiveness of compacting loosened ground has also been highly evaluated. Our company has extensive experience in subsidence countermeasures and void filling work while maintaining daily operations in logistics warehouses and factories. With eight branches nationwide, we are equipped to respond to issues related to ground subsidence and voids beneath floors, so please feel free to contact us if you have any concerns. ■ Construction case studies (Teratec method service site): https://teretek.jp/repo/r180

Mainmark will form a business partnership with JALOC, a company that manufactures and sells advanced material handling equipment, to promote the introduction of automation equipment in the logistics industry. In the logistics and warehousing sectors, the introduction of automation equipment, including industrial robots, and the improvement of productivity have become urgent needs. A necessary condition for the introduction of automation equipment is that the floors of production facilities must be level. Through the partnership between the two companies, it has become possible to support companies that have previously hesitated to introduce equipment due to the time and costs associated with floor repairs.

At Mainmark, we will be exhibiting at the "2nd Factory Equipment and Supplies Exhibition," which will be held in February 2020, featuring 2,030 companies specializing in equipment and supplies necessary for factory users, starting with the manufacturing industry. At the exhibition, we will showcase demonstrations of the Teratech method, as well as provide information such as construction videos.

We have started selling our original low-density filling method "Terrafill," which involves mixing "cement milk" and "foam" for placement. By using low water content (water-cement ratio of 50%) cement milk compared to conventional methods, it offers excellent stability of quality after dehydration and drying, despite being a low-density filling material. Furthermore, it allows for construction with a compact plant compared to traditional methods. It can be applied in various locations such as filling voids under buildings, abandoned pits, decommissioned pipes, abandoned shafts, and air raid shelters.

Thank you very much for your continued support. We sincerely apologize for the inconvenience, but our company will be closed for Golden Week from Saturday, April 27, 2019, to Monday, May 6, 2019.

"TerraTech" corrects the slope and subsidence of concrete floors without damaging the floor or stopping operations. "TerraTech" comes with a 5-year warranty based on the insurance of a major insurance company (subject to approval). The correction of the concrete floor is backed by the reliable "TerraTech" with a warranty, providing a different level of peace of mind.

The method of leveling sunken concrete floors by utilizing the foaming and expansion force of urethane resin was devised by Dr. Hakkinen in Finland in the 1970s and spread worldwide under the name "Uretech." In Japan, in July 2001, Mainmark Japan Co., Ltd. (which became Uretech Japan in 2007 and Mainmark in 2015) began construction of the "Uretech method" based on a licensing agreement with "Uretech Worldwide (Finland)," the licensee for sunken correction using Uretech resin. Then, in April 2017, the licensing agreement with "Uretech Worldwide" was amicably terminated, and a unique urethane resin with strength and characteristics suitable for sunken correction and void filling in Japan was developed. This resin, which considers the global environment, will continue to be used under the name "Teratech," inspired by the Latin word "terra," meaning "earth."

"To repair what already exists and use it longer rather than creating something new." Japan is one of the world's leading earthquake-prone countries. Buildings in Japan are constantly exposed to dangers such as earthquake disasters and ground subsidence. "Our role at Mainmark is to 'return tilted buildings to a level position' and 'prevent existing buildings from tilting.'" We are refreshing our image and starting a new challenge!!
