Underground buried pipes, underground cavities, concrete diagnosis - high mobility and rapid exploration are possible.
Ground-penetrating radar (GPR) is a non-destructive exploration method that utilizes electromagnetic waves. A radar antenna placed on the surface (100 MHz to 1.6 GHz) emits electromagnetic waves towards the ground, and receives the waves that are reflected back from various underground objects (material boundaries). The received reflected waves are processed and displayed as subsurface images. Compared to trial excavation surveys, it is cost-effective and allows for continuous exploration. It has high mobility and enables rapid surveying. It can explore regardless of the material of the target objects (pipes, cavities, rebar, structures, etc.). Exploration is possible up to a depth of about 3 meters (this may vary slightly depending on soil conditions). For more details, please download the catalog or contact us.

A comfortable and convenient life, along with the blessings of nature. We need both of these. While making our communities safer and more comfortable, we must protect the natural environment. It's a challenging theme, but if we face it seriously, we can surely achieve it. What makes this possible is creativity and technology. Kowa will leverage the technical know-how we have accumulated and continue to strive for a balance between the two.
