CONCRETE CHOICES
All concrete orders are custom mixed on site. Our trucks mix standard specifications of 2500 PSI to 7000 PSI, and we can do custom-design mixes as well. We also supply 3/4″ round-concrete rock and 3/8″ pea gravel upon request.
Here are some examples:
- 2500 PSI: Fence posts
- 4000 PSI: Sidewalk, footings, patios, dog runs, trash slabs, shed slabs, pier pads, stairs, driveways, approaches, footings, foundations, retaining walls, garage floors, hot tub pads, RV slabs, shop floors, etc.
- 4500 PSI: City, county, state and winter mix

Concrete Definitions
All our mixes are chemically air-entrained. This means microscopic bubbles are introduced into the fluid concrete allowing expansion and contraction of the hardened concrete. This provides increased resistance to temperature changes (freezing and thawing) and minimizes cracking. Air-entrainment also greatly improves workability, giving semi-liquid concrete a “creamy” look and feel. Less water is required in all mixes, and the billions of air bubbles (400-600 billion per cubic yard) reduce “bleeding” (separation of the water from the paste), resulting in a more durable concrete.
The term “slump” refers to the fluidity or stiffness of semi-liquid concrete. Unlike ready-mix, our truck operator controls the amount of water being added to your mix as it is being delivered, assuring you the slump you desire.
Fiber mesh is a mass of small polypropylene fibers that can be added to your mix upon request. The fibers are uniformly distributed throughout the mix and provide added protection from cracking due to shrinkage and expansion.
This additive is used upon request, usually during the winter, to enhance curing.
Hot water is used during the winter months to help the chemical process start in cold weather, so finishing can be completed properly.
