Underground utility construction services
From a single buried drop to a mainline fiber build-out, MDT Underground handles the drilling, trenching, splicing, and restoration work that gets connectivity infrastructure in the ground — on schedule, done right the first time.
Drop bury infrastructure solutions
Three core disciplines, built to work together on the same job site — so a client never has to hand a project off between contractors mid-build.
Underground Construction
Our underground construction services support the installation of critical utility infrastructure — conduit, pathways, and underground network systems — using whichever method the site calls for, trenchless or open-cut.
Fiber Optic Construction
As a fiber optic construction contractor, MDT supports broadband expansion through professional fiber installation, mainline construction, splicing, and testing — plus the enclosures that protect the network long after the crew leaves.
Utility Installation
MDT provides fiber-to-the-home (FTTH) deployment, phone line burying, and municipal and community drop bury support — the last-mile work that actually gets a home or business connected.
The right method for the ground you've got
Not every project needs the same tools. Here's how our we map our approach to the installation methods required for each job:
| Directional Boring (HDD) | Open-Cut Trenching | Vibratory Plow | |
|---|---|---|---|
| Conduit & Duct Bank | — | ||
| Mainline Fiber | |||
| FTTH / Last-Mile Drops | — | ||
| Buried Service Wire (BSW) | — | ||
| Phone Line Burying | — | ||
| Utility Relocation | — |
