Mainmark Structural Consulting Co., Ltd. (President: Akitoshi Nishimura, hereinafter referred to as "Mainmark SC"), a group company of Mainmark, has agreed to collaborate with Sompo Japan Insurance Inc. (President: Keiji Nishizawa, hereinafter referred to as "Sompo Japan") and Pasco Corporation (President: Hideki Shimamura, hereinafter referred to as "Pasco") to jointly work on the creation of insurance products and services related to disaster prevention and mitigation utilizing ICT sensing technology in the event of natural disasters such as typhoons and heavy rains.

Mainmark is pleased to announce the absorption merger with its group company, Mainmark Aquatech Co., Ltd., which manufactures underground drainage pipes used for liquefaction countermeasures and other construction works. ■ Background and Purpose of the Merger In Japan, where natural disasters such as earthquakes frequently occur, the aging of buildings and structures caused by ground subsidence is a serious issue. Our company has been engaged in the design and construction of works related to correcting and preventing the tilting of existing buildings, using the "TerraTech Method," which involves injecting rigid polyurethane resin under concrete floors to restore the floor to a level position through its expansion force. With this absorption merger, we aim to strengthen our comprehensive proposals for correcting and preventing the tilting of existing buildings by integrating our technologies with the expertise and knowledge of Mainmark Aquatech in liquefaction and landslide countermeasures. ■ Overview of Mainmark Aquatech Company Name: Mainmark Aquatech Co., Ltd. Location: 5-2-3 Nishikasai, Edogawa-ku, Tokyo Representative: President Toshitaka Shimizu

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.

The total construction achievements of our main brand, including the "Teratec Method" for sinking correction work, have surpassed 3,500 cases. We sincerely thank you for your support. We look forward to your continued patronage.

We will be holding a demonstration and seminar to collectively answer the questions from everyone regarding the "TerraTech Method"! At the Mainmark headquarters, we will not only explain the method but also conduct a demonstration that lifts a 90-kilogram weight using the expansion force of "TerraTech Resin." Participants will receive a collection of unpublished materials on the "TerraTech Method." 【Event Overview】 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━■□ 【Date and Time】 　September 6, 2019 (Friday) 　10:00 AM - 11:30 AM 【Location】 　Mainmark Corporation Headquarters 　7th Floor, NEXTAGE Nishikasai Building, 5-2-3 Nishikasai, Edogawa-ku, Tokyo 【Participation Fee】 Free 【Participant Benefits】 Unpublished materials on the TerraTech Method ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 【How to Apply】 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━■□ The application method is detailed in the announcements on the TerraTech Method website. *As seating is limited, if there are many applications, we will close registration once the capacity is reached.

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!!
