  • How much rock do I need for my project?

    The quantity of rock or aggregate required typically corresponds to the dimensions of your project. To receive guidance on the total amount of product needed, please provide us with the square footage and depth of your project.
  • What strength of concrete would be best for my project?

    The optimal concrete strength is determined by your specific project requirements. For most residential projects such as driveways, sidewalks, and garages, concrete with a strength of 3000-3500 PSI is suitable. Commercial projects like parking lots or warehouse floors generally require concrete with a strength of 4000 PSI or higher.
  • What is air entrainment concrete?

    Air entrainment concrete is a specialized type that incorporates air bubbles to enhance durability and resistance to freeze-thaw cycles. This type of concrete is primarily used for exterior applications exposed to the elements, including sidewalks, driveways, and parking lots - essentially any uncovered and unheated concrete surface.
  • What time of day do you load product?

    Our preferred loading times are typically in the morning, though we continue loading throughout the day. To ensure completion of work before closing, our daily product loading cutoff is approximately 3:00 PM.
