IMI Systems

About IMI Systems

IMI comes from the Hawaiian word ʻimi, meaning to search, seek out, or investigate. It reflects a deliberate, methodical approach to understanding what lies beneath the surface before decisions are made.

IMI Systems applies this principle through professional subsurface locating and mapping, using advanced detection and mapping technologies to uncover hidden conditions below ground. Built in Hawaiʻi and shaped by its complex terrain, our work is focused on clarity, accuracy, and reducing risk so projects can move forward with confidence.

Our Recent Projects

Examples of recent Maui work focused on finding, mapping, and documenting what’s on and below the ground.

Client Testimonials

We've used Nohea at Imi Systems to locate and mark water lines during tree work to not damage any underground piping during removal. The tree root mapping was also very useful to tell when a tree growing close to a house might pose a risk to the foundation.​

What Tree Services
We utilized ʻImi Systems to complete drone mapping of our wetland area prior to grading, creating a clear baseline for the site. The before-and-after aerial data allowed us to monitor changes accurately throughout the project. Their mapping provided valuable insight for planning, documentation, and long-term site management.

We’ve been extremely happy with how quickly ʻImi Systems locates unknown cesspools for our real estate clients, even on tight timelines. It has been really beneficial to help our seller to complete disclosures and avoid last-minute issues during a sale.
