"MPD Pipe," a drainage pipe with excellent water collection performance, strength, and maintenance characteristics.
MPD pipe
For groundwater drainage measures against liquefaction and drainage of artificial ground such as embankment construction sites.
The "MPD Pipe" is a drainage pipe (drain pipe) with a three-dimensional mesh structure formed from fibrous polypropylene in a porous state. It is used in groundwater lowering methods through propulsion techniques and serves as a drainage pipe for artificial ground such as liquefaction countermeasures and embankment construction, as well as for preventing sliding collapses.

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"
