Portland & Southern Washington

Commercial Concrete Contractors Servicing Portland & Southern Washington

As a leading commercial concrete contractor in the Portland and Southern Washington area, The Conco Companies is providing services to meet the rapidly growing construction market. We’ve expanded our commercial concrete services to include concrete forming, post-tension cable, shotcrete, structural concrete, and rebar fabrication.  With over 60 years of experience, we deliver dependable services and have a vast portfolio of noteworthy and large-scale projects from throughout the Western U.S.  Our concrete work spans commercial, industrial, educational and multi-residential construction, as well as public works and highways.  Our specialized teams are focused to handle any project.

Unsurpassed Commercial Concrete Construction Services for Portland & Southern Washington

Conco’s team of professional concrete contractors in the Portland area brings the highest level of integrity and principles to each project from the pre-construction phase to completion.  We are a trusted leader in the industry and offer a full range of services:

    • Structural Concrete

      When your building needs high-quality concrete to properly support it, Conco is your choice for structural concrete placement. Our teams are trained in industry best standards and practices and use the most advanced field tools to ensure a quality job.

    • Shotcrete Services

      Quality and Economical. As an early innovator in a variety of shotcrete applications, we can show you how to complete your project faster and more economically than by using traditional cast-in-place concrete. Our experienced team includes engineers and estimators as well as our ASA (American Shotcrete Association) certified and highly trained nozzlemen. The shotcrete process minimizes formwork and offers the ability to construct straight, curved, or irregularly shaped surfaces easily while still providing the structural characteristics of conventional methods.

    • Concrete Forming

      When you choose Conco, you have our guarantee that you will get the finest workmanship on any type of concrete formwork. Our team will recommend the proper materials to use in order to provide your project with the most cost-effective forms that meet the job’s specifications and requirements. Additionally, all of our projects start with a plan for the safety of all on-site crew members and other workers while adhering to all regulations.

    • Post-Tension Cable Suppliers

      Our high-quality post-tensioning cable meets or exceeds the most stringent engineering specification and requirements. With decades of experience under our belt, we will help you complete your project in the most economical, efficient way by providing exceptional customer service, a quick turnaround, and the best value.

    • Rebar Fabrication

      Conco is the largest independent reinforcing steel contractor on the West Coast and operates two rebar fabrication facilities.  Our newest facility in Rochester, WA is located halfway between Seattle and Portland.  Recognizing the increasing construction in the area, we have made significant capital investments to both equipment and facilities.  In our Rochester plant, we have doubled capacity by adding a second shear line, a new overhead crane, and a new #14 rebar bender.
