Expertise and Experience.
"Client First" Service.
Established in 2006 by Shotcrete industry veteran Jon Harpole, NSI began as a family owned and run company specializing in small commercial projects. After spending several years honing our craft within the greater Southern California area, NSI began expanding its reach both north and south and now serves all of California, from San Diego to Sacramento. Today, NSI is an industry leader and innovator managing projects ranging from retaining walls to multi-million dollar multi-level parking structures and seismic retrofits.
As veterans in the Shotcrete industry with three decades of experience, The Harpoles have developed ground-breaking techniques to revolutionize the Shotcrete industry. To this day, they strive to find a more efficient way to place and finish Shotcrete. Even down to their revolutionary process of cleaning up and disposing of rebound waste, NSI never rests until every aspect of every project is handled with precision and punctuality.
At NSI, we treat each client and each project with the same amount of professionalism and care. It is our "client first" mission statement that has earned NSI several long-standing relationships through the years. We place a high value on each of these relationships and treat each client and every project, be it large or small in scope, with the same dedication and focus. The goal is to assist our clients in exceeding their schedule and budgetary goals while maintaining the highest quality level of Shotcrete in the industry. This is the foundation which we have built our reputation on.
Today, NSI is led by President Jon Harpole and Vice-President Jordan Harpole. Our General Superintendent Gene Lamberth along with our Operations Manager Kalo Franklin oversee the field operations. The Southern California Team is headed by Dan Franklin, with Spencer Bigger and Jake Hinck. Our Northern California team is headed by Deane Hudson, with Neil Barton and Paul Mendoza.
