Micro Trenching · Serving the Phoenix Metro
Micro Trenching for Fiber & Underground Utilities
Microtrenching is a minimally invasive underground utility installation method that cuts a narrow, shallow trench, typically 1 to 2 inches wide and 12 to 24 inches deep, directly into the pavement surface. Fampa Construction places fiber-optic cable, conduit, and other utilities inside the trench, then seals it with a specialized backfill material to restore the roadway. #WeDrillin

When to call our microtrench crews
If any of these describe your route, microtrenching is likely the fastest, cleanest way to get conduit in the ground and the street back open.

Cut to seal in 4 steps
Route Walk & 811
We walk the alignment, file the 811 ticket, review locates, and pothole any crossing that needs physical verification.
Cut & Place
The microtrencher cuts a 1 to 2 inch slot at 12 to 24 inches deep, then conduit and tracer wire drop in behind the saw.
Backfill & Seal
Specialized backfill material is placed and sealed flush with the pavement so the roadway is restored in the same pass.
Test & Close Out
Rod-and-rope or mandrel proofing, as-builts, and a clean site walk before we turn the route over.
LESS DISRUPTION, FASTER FIBER DEPLOYMENT
Microtrenching is a minimally invasive underground utility installation method that cuts a narrow, shallow trench, typically 1 to 2 inches wide and 12 to 24 inches deep, directly into the pavement surface. Fiber optic cables, conduit, and other utilities are placed inside the trench, which is then sealed with a specialized backfill material to restore the roadway.
Compared to traditional open-cut trenching, microtrenching is faster, more cost-effective, and less disruptive to traffic, businesses, and surrounding infrastructure. It's the preferred solution for deploying fiber networks and utilities in urban environments, along roadways, and in areas where minimizing surface damage and restoration time is critical.
Fampa Construction runs microtrench routes end-to-end across the Phoenix Metro: 811 and potholing, permitting and traffic control, saw cutting, conduit and tracer wire placement, specialized backfill and sealing, and clean as-builts at closeout, all under one AZ ROC #339873 licensed contractor.

Straightforward microtrench pricing
We scope and price every route before we mobilize, per-foot for standard runs, route-priced for full ISP builds, and MSA pricing for ongoing programs.
Per-Foot Microtrench
Priced by linear foot based on pavement type, depth, and conduit count.
Route Program
Route-priced ISP fiber builds with permitting, traffic control, and restoration included.
MSA / Program Support
Dedicated microtrench crews for carriers and ISPs running ongoing Phoenix Metro programs.
Final pricing depends on pavement type, depth, conduit count, traffic control, and jurisdictional restoration requirements.
Microtrench plan & bid in 48 hours, no bait pricing
