We provide engineered products for engineered applications and proudly count among our customers State Departments of Transportation, major cities and counties, public authorities and numerous private entities.

Regional contractors can be assured that County Materials has the concrete pipe and related products for nearly all their large volume stream, storm and flood water projects.


Concrete pipe has a rich history, spawning an industry that today produces an economical, high quality product for numerous applications. It's been in use for over 5,000 years. In North America, concrete pipe has been used extensively in drainage and sanitary sewer systems since the 19th century.

Product Performance

The performance requirements of each pipe joint are generally determined by the function of the pipeline. Whether the purpose is to convey sanitary sewage or stormwater, joints are designed so that when sections are laid together they will make a continuous line of pipe with an interior free from irregularities. Joints can be designed to provide soil-tightness or water tightness, with the ability to accommodate deflection or longitudinal movement, and strength to handle shear or vertical movement.

Concrete pipe and precast products must efficiently convey the fluid for which they are designed. Secondly, they are structures, and must be able to support the weight of the earth, as well as live loads above it. Unlike alternate products, concrete pipe accomplishes both functions through its inherent strength and rigidity.

Benefits to using Pipe and Precast

  • Adaptability
    Pipe and precast can be designed, built and installed to meet an enormous range of project requirements
  • Strength
    Both can be designed to withstand any combination of loading with minimal embodiment support
  • Hydraulic Efficiency
    A demonstrated, documented Manning's "n" value of 0.012
  • Availability
    Produced locally to meet local needs
  • Economy
    Offers long service life and is proven to be cost-effective pipe material

County Materials' manufactures a complete line of reinforced concrete pipe, box culverts, apron end walls, manholes, lift stations, catch basins and other precast concrete products used in construction. Because of it's superior durability, strength and joint system performance, concrete pipe and precast products remain the choice for engineers and owners of drainage and sanitary sewer projects.
Why choose Concrete Pipe?

Amer-I-line Concrete Pipe

Amer-I-Line Concrete Pipe are manufactured with an integral liner that provides an economical alternative for corrosive environments featuring storm water and sewer management systems and structures.
