Services
Underground construction services in Illinois
Horizontal directional drilling, conduit installation, fiber optic installation and underground utility construction — built to the print and documented for closeout.
01What we build
Four core services. One standard of work.
Each service can be delivered on its own or combined into a complete underground scope.
Horizontal Directional Drilling
Trenchless bores under roads, driveways, sidewalks and landscaped areas, with minimal surface disruption.
Learn moreFiber Optic Installation
Pulling and placing fiber optic cable through new and existing conduit, built to the construction print.
Learn moreConduit Installation
Single and multi-duct conduit runs placed to depth and route, proofed and ready for cable.
Learn moreUnderground Utility Construction
Handholes, vaults, core holes and restoration — the work that connects a route end to end.

03For general contractors
A fiber construction subcontractor that closes out clean.
ZMB Utilities works as the underground subcontractor on fiber builds for telecom owners and general contractors — from the print to the as-built.
Priced from the print
Send the construction print and the scope. Bores, conduit, fiber placement, access points and restoration are priced as drawn.
Segment-by-segment coordination
Work is scheduled and coordinated with your team segment by segment, with field changes raised as they happen.
As-builts for closeout and billing
Crews mark completed work on the print in the field; the office turns it into as-built prints that match what was installed.
