Choosing the Right Base Material for Your Patio: 3/4" Clean Stone vs. Quarry Process

When it comes to building a patio that stands the test of time, the foundation is key. Two popular choices for patio base materials are 3/4" clean stone and quarry process. Each option has its unique characteristics. Being understanding of these characteristics will allow you to make the best decision when installing your hardscape project.

1. Understanding 3/4" Clean Stone:

   Composition: 3/4" clean stone is composed of crushed granite or limestone. The stones are screened to ensure uniform size, with the largest stones typically measuring 3/4 inch in diameter.

   Drainage: One of the key advantages of 3/4" clean stone is its excellent drainage properties. The uniform size allows for effective water runoff, preventing pooling and water damage beneath the patio surface. There is no “fines” in the stone meaning there is no dirt, sand, or dust allowing for no water to be absorbed. With no water adhering in the base, during the freeze thaw period, the stone base will not shift since there is no water expanding or contracting. ¾" clean stone is not just used as a base material, but it is also the first choice for drainage solutions.

   Stability: The consistent size and angular shape of the stones provide a stable base, reducing the risk of settling over time. The angular nature of the stones allows them to interlock with one another allowing for natural compaction. Before running a plate compactor over the stone, the stone is already naturally compacted due to its nature. This stability is crucial for maintaining the integrity of your patio.

2. Exploring Quarry Process:

   Composition: Quarry process (QP), also known as crusher run or dense-grade aggregate, is a combination of crushed stone and stone dust. It is a mix of various sizes, ranging from fine particles to 3/4 inch in diameter. With the variety of particles, water can be absorbed by some of them which can cause the base to shift during the freeze thaw cycle in certain climates. A shifting base is never ideal.

   Compaction: Quarry process is known for its ability to compact well. The combination of different-sized particles allows for a tight, solid base that can withstand heavy loads without settling.

   Cost-Effectiveness: Quarry process is often more affordable than 3/4" clean stone, making it an attractive option for budget-conscious homeowners.

3. Choosing the Right Material for Your Patio:

   Consider Soil Conditions: If your soil has poor drainage (commonly clay soil), 3/4" clean stone may be the better choice due to its superior drainage capabilities.

   What Climate Are You In: If you are in a freeze thaw climate, using ¾" clean stone will give you a stronger base that won't shift due to its moisture wicking ability. Unlike Quarry Process, ¾" clean stone does not have fines in it which allow for no water to be absorbed allow for better drainage and a stronger base.

   Consult with a Professional: It's always a good idea to consult with a landscaping professional or contractor who can assess your specific site conditions and recommend the best material based on your project requirements.

 Choosing between 3/4" clean stone and quarry process as the base for your patio involves considering factors such as drainage, stability, and budget. By understanding the characteristics of each material, you can make an informed decision that ensures a durable and long-lasting patio foundation.
