Mitsui E&S Technical Research has developed a multi-path radar (hereinafter 'MPLA Radar') capable of reproducing exploration results in 3D images. This technology is utilized for inspecting concrete structures like roads, railways, and tunnels, as well as for rebar exploration. By practicalizing this as a non-destructive inspection device for the first time in the industry, we have provided an electromagnetic wave radar exploration*1 system that contributes to improving work efficiency in the infrastructure inspection field.
The moisture detection device (hereinafter 'this device') was developed by Daiwa House Industry as a non-destructive inspection device that detects moisture and other substances inside housing walls. It combines Daiwa House Industry's moisture detection technology with Mitsui E&S Technical Research's MPLA Radar technology*2.
Moisture content is said to be one of the factors causing material degradation that greatly affects the lifespan of buildings such as houses.
This device can display the detected high-moisture areas inside the walls in red, making it a tool where even general technicians can easily identify areas with high moisture content.
Furthermore, to accommodate moisture detection inside the exterior walls of houses, it is based on Mitsui E&S Technical Research's concrete structure inspection device 'MPLA-1645A', adding optimization and adjustments specifically for the moisture detection of residential exterior walls.
Mitsui E&S Group, together with Mitsui E&S Technical Research, will continue to verify its convenience through trial introductions at Daiwa House Industry and its group companies. Through development and cooperation toward practical application, we will promote the deployment of MPLA Radar technology to various fields and applications not previously targeted, such as non-destructive inspection devices for housing.
