      Florida Homeowners Choose Ready-Mix Concrete for Diverse Residential Applications

      Ready-mix is a long-lasting, sustainable paving material well-suited for a variety of residential applications.

      Walkways and Driveways

      Ready-mix concrete is an ideal solution for high-traffic areas such as walkways and driveways. Its inherent strength and minimal maintenance requirements allow it to withstand harsh outdoor environments and frequent vehicle and foot traffic.


      Concrete pools are customizable and offer a variety of shapes, sizes, and depths, achieving almost any aesthetic. Ready-mix concrete is compatible with tile, concrete pavers, and a variety of pool deck materials. The use of shotcrete, a method of applying concrete projected at high velocity to form vertical or curved surfaces with high compressive strength, allows for variable depths, tight radiuses, and built-in seats and steps.

      Learn more about why you should use ready-mix concrete for your swimming pool project.


      Homeowners often choose ready-mix concrete for their patios and outdoor living areas because of the plentiful design options available. Colored and decorative ready-mix allows for customization and enhances any paving project.

      County Materials offers products for coloring and texturing concrete, including coloring agents and hardeners, colored cementitious toppings, stains, curing and sealing agents, coating and caulking materials, and treatments for exposing aggregates. Our coloring agents are available as integral, shake-on, and stains and are determined by specification.


      In addition to vehicle impact and fluctuating temperatures, years of exposure to chemicals like oil and gasoline can take a toll on any garage floor. Concrete provides a resilient surface that holds up against spills, drips, and impacts, remaining functional throughout the decades.

      County Materials supplies high-quality ready-mix for residential applications throughout Central Florida. For more information, call our Customer Service Team at (352) 343-8488.
