SUBSURFACE EXCELLENCE

We fix what you can’t see —
without tearing up what you can.

Our crews specialize in trenchless rehabilitation and retrofitting of critical underground infrastructure. We use advanced robotics, UV-cured liners, and real-time CCTV to deliver surgical precision repairs with minimal surface impact.

MAG Spec • ADEQ • OSHA VPP

CCTV Inspection & Diagnostics

High-definition robotic cameras with laser profiling and sonar. We deliver full NASSCO PACP/MACP reports within 48 hours.

Cured-in-Place Pipe (CIPP)

UV-cured fiberglass liners for 4"–96" pipes. 50+ year design life. No excavation required in most cases.

Pipe Bursting & Static Bursting

Replace failing pipes with new HDPE or PVC while fracturing the old pipe in place. Ideal for upsizing.

Hear from the municipalities and developers who trusted us with their most critical underground assets.

City of Mesa Public Works Director
Michael Torres, P.E.
Director of Public Works • City of Mesa
“Pinnacle completed a 4,800-ft CIPP rehabilitation on our 54-inch interceptor in 11 days with zero service interruptions. Their real-time monitoring and daily reporting gave our council complete confidence. We’ve already awarded them three more contracts.”
— 2025 Arizona Public Works Project of the Year
TSMC Arizona Facilities Director
Dr. Lena Park
Director of Site Infrastructure • TSMC Arizona
“When we discovered major sinkhole risk above our 36-inch force main feeding the fab, Pinnacle deployed their subsurface rescue team within 4 hours. They stabilized and rehabilitated 1,200 feet using pipe bursting — on schedule and 22% under budget.”
