Underground Utilities

It’s easy to stick a pipe in the ground. But that pipe, when covered with dirt and hidden from view, must hold up for a century. Achieving that result requires advanced technology, like laser projectors that plot elevation lines on distant markers, and nuclear gauges that measure soil moisture and density.

Every season, Kerr Contractors, Inc. underground crews lay miles of pipe-ranging from one inch to 108 inches in diameter-for water lines, sanitary sewers, and storm sewers. Related structures include intakes, detention systems, box culverts, and pump stations.

Kerr Contractors, Inc., has distinguished themselves as Oregon’s largest installer of welded steel pipe. This application is best suited for water transmission main. These projects require additional resources to handle the large diameter pipe and the expertise to precisely weld each joint to ensure a proper joint.

Productivity is enhanced by custom-configured excavators with wider tracks, longer booms, and bigger buckets. Vibrating compaction plates assure proper soil compaction where it matters most-where you can’t see it. With these powerful tools, Kerr Contractors, Inc. crews can lay more pipe per day.

Underground work has its own set of disciplines and methods. Because workers are in the trench, safety is imperative, so the slope of the cut is important. All Field Supervisors have completed advanced training and are OSHA certified. Kerr Contractors, Inc. lays pipe in only one way — the right way.
