FEATURED PROJECTS
The best way to understand how we work is to see what we've done. The projects below show ICG applying cathodic protection, corrosion surveys, condition assessments, and coating inspection to real infrastructure across the Mountain West. Each one reflects how we approach a problem: gather the right data, interpret it with engineering judgment, and give our clients clear, defensible recommendations they can act on.
INDUSTRIAL PROCESS PIPELINE ASSESSMENT
When a 22,400-foot industrial process pipeline experienced a suspected corrosion-related failure, ICG was engaged to identify root causes, locate high-risk sections along the alignment, and develop a corrosion protection strategy to restore reliable performance. The four-task assessment program combined soil corrosivity testing, a current-interrupted close interval potential survey, an alternating current voltage gradient (ACVG) survey, and pipeline vault inspection. The completed work identified high-priority locations for direct verification and forms the basis for ICG's recommendations on cathodic protection upgrades, electrical isolation improvements, and targeted repairs.
DRONE CONDITION ASSESSMENT
Drone-based inspection has transformed how water tanks and hard-to-reach assets are evaluated. High-resolution aerial imagery captures detailed exterior conditions in a fraction of the time of manual inspection, with better data, lower risk, and no scaffolding required. ICG uses drone work to document existing conditions, monitor rehabilitation progress, and verify coating quality against specification.
LONG-TERM DATALOGGING
Light rail transit systems generate dynamic stray currents that traditional pipe-to-soil "snapshot" surveys can miss entirely. ICG designs long-term datalogging programs that capture continuous data over days or weeks, revealing the patterns and peak interference levels that single-point surveys never see.
NEWS
ICG presented at the AWWA conference in Sun Valley, ID on how above-ground survey techniques like CIS and ACVG can identify anomalies and coating defects along a pipeline, and how risk analysis can prioritize high-risk lines once consistent data is available across a system.

NEWS
The U.S. has more than one million miles of water pipeline and an estimated 240,000 water main breaks per year. The 2017 ASCE Infrastructure Report Card gave water systems a D grade. Erik presented at the APWA Fall Conference on a practical framework for assessing corrosion risk on water mains and evaluating mitigation alternatives.
