Your partner across manufacturing, design and field support.
Thompson Pipe Group (TPG) is a major North American manufacturer, offering one of the most diverse product portfolios for gravity and pressure sewer, water, sliplining, trenchless, and other critical infrastructure applications.
As the only privately held, family-owned manufacturer of this scale in the industry, TPG has grown from humble beginnings to encompass seven manufacturing locations across the United States, each housing multiple specialized production plants. Our extensive capabilities include reinforced concrete pipe (RCP), steel pipe, bar-wrapped pipe, PCCP, microtunneling pipe, polymer structures, fiberglass-reinforced polymer (FRP) pipe, and composite systems – positioning TPG as the sole manufacturer offering this breadth of pipe products in diameters up to 169 inches.
Bring It On — A Legacy and a Future in Construction
Our story begins in 1977, when Ken M. Thompson founded Ken Thompson, Inc., an underground utilities contracting company focused on excavating and installing large-diameter concrete pipe. The invaluable experience gained in the field would shape our approach to the industry forever.
In 1988, Ken took the next bold step by applying his contracting expertise to manufacturing, and Rialto Concrete Products was born. This shift brought hands-on construction knowledge into the precast pipe manufacturing world. By 2009, the business took a strategic turn for the Thompson family, pivoting to a full focus on expanding manufacturing operations and leaving the installation to our clients. This evolution culminated in 2015 with a name change to Thompson Pipe Group, unifying our growing capabilities under one brand.
Today, we are not only a leader in manufacturing, but our Pipeline Services team also provides year-round support for emergency pipe and parts needs. TPG can provide everything from the simplest fitting to large-diameter pipes, sourcing directly from E-Stock located at any of our plants. We understand what it takes to build at scale, and we continue to invest in products and processes that make infrastructure easier to design, construct, and maintain.
We also carry forward the industry’s early history by maintaining the Price Brothers’ archival pipeline plans – valuable records from one of the pioneers of concrete pressure pipe – as well as historical records from Gifford-Hill and other acquired assets. This archive accounts for nearly 80 percent of the country’s large-diameter concrete pressure pipe installations.
Guided by this legacy, we focus on making each generation of products better than the last as we continue to build our nation’s underground infrastructure.
