Quarry in Dauphin County


For more than six decades, we at Union Quarries have dedicated ourselves to providing Harrisburg, Hershey and the rest of Dauphin County with asphalt, concrete and stone aggregates. Our goal is to ensure every construction site in Central Pennsylvania has access to safe and sustainable resources for all of its project needs.

Aggregates Available in Dauphin County

Our aggregate offerings consist of dozens of types of AASHTO, rip rap and modified stone in various sizes and compacting abilities. Whatever project you need stone for, we have your solution. Many of our customers come to us when they need aggregates for:

  • Construction entrances and ditch lining: Before you begin your project, it’s important to ensure your construction site is ready for all the machines that will roll through. A coarse blend like AASHTO #1 works well for construction entrances and ditches.
  • Walkways and driveways: If you’re laying an off-road path for people or cars, an aggregate with midsize particles is best. An option like AASHTO #57 washed is ideal for this application.
  • Road fill: The main requirement for road fill aggregate is that it doesn’t compact over time. Drainage ability and aggregate compounds can vary based on preference. For this application, our suggestions include PA 2A or 2RC stone.
  • Water landscaping: Create a clear separation between land and lake with rip rap aggregates. Sizes range from 3-inch to 6-inch boulders in R3 to boulders up to 42 inches in R8.

Asphalt and Concrete

Our products also include asphalt and ready-mix concrete. We’ve spent years perfecting our mixes to ensure their quality and reliability.

At Union Quarries, we use an advanced production process to deliver superior, pure blacktop that’s free of shingles and reclaimed asphalt pavement (RAP). We ensure every batch of asphalt we produce is stable, durable and fatigue-resistant. It’s flexible and workable so your team can get the job done correctly the first time without cracks.

We also formulate our mix with skid-resistant qualities, which can prevent hydroplaning. Safety is essential in the field of construction, and we strive to keep conditions safe on our job site and yours.

Our ready-mix concrete saves you from spending money on expensive mixing equipment — and it saves your crew time. We’ll deliver it right to you so you can keep your project on schedule. If you need help calculating water-to-cement ratios, we can help with that as well.
