Granular a vs. Clear Stone: Understanding the Differences

Granular A and clear stone are two commonly used materials in construction and landscaping projects. While they may appear similar at first glance, there are some key differences that make them unique. It’s made up of various sizes of crushed rock, ranging from fine particles to larger stones. On the other hand, clear stone consists of the same Granular A stone, but it undergoes further processing. It’s passed through a sleeve that separates the rocks based on their size, resulting in stones that are all the same size. This uniformity in size makes clear stone ideal for applications where water drainage is crucial. In particular, clear stone is commonly offered to consumers in two sizes: ⅜” and ¾”.

What Is Granular Gravel?

Granular A, also known as A Gravel, is a type of crushed gravel material that consists of stones ranging in size from 3/4″ down to sand particles. It’s commonly used as a top coat before asphalt is laid. The main characteristic of Granular A is it’s ability to grade easily and compact tightly, making it suitable for use in high traffic areas.

It’s compact nature ensures that it won’t easily shift or loosen, even under heavy traffic conditions. This makes it ideal for areas such as driveways, parking lots, and roadways.

Furthermore, Granular As composition allows for proper water drainage, which is crucial in preventing water buildup and potential damage to the surface. This material has excellent permeability, allowing water to pass through and preventing pooling. Proper drainage also helps to maintain the stability and integrity of the surface.

Whether it’s for residential or commercial use, this type of gravel material provides a strong foundation with excellent drainage capabilities. By understanding the differences and advantages of using Granular A over clear stone, you can make informed decisions when it comes to your construction or landscaping projects.

The Difference Between Granular a and Clear Stone

Granular A and clear stone are both types of aggregate materials commonly used in construction and landscaping projects.

Granular A refers to a specific type of crushed stone that’s manufactured to a specific size and shape. It’s typically composed of a mixture of sand, gravel, and crushed rock. Granular A is often used as a base material for roads, driveways, and building foundations due to it’s strength and stability.

Clear stone, on the other hand, refers to a type of crushed stone that’s been screened to remove any larger pieces or debris. It’s commonly used in drainage systems, landscaping projects, and as a decorative stone. Clear stone is typically more aesthetically pleasing and can add visual appeal to outdoor spaces.

In summary, the main difference between granular A and clear stone lies in their composition and intended use. Granular A is primarily used for structural purposes, while clear stone is often used for drainage and decorative purposes.

In addition to it’s efficient use of aggregate, clear stone offers several benefits in construction projects. It provides excellent drainage capabilities, allowing water to flow freely through the material. This reduces the risk of water accumulation and the potential for damage to the project in the long run. Clear stone also offers stability and durability, allowing it to withstand heavy loads and harsh weather conditions. These qualities make clear stone a preferred choice for various applications, including road construction, landscaping, and foundation installations.

Will Clear Stone Settle?

When it comes to the installation process, one important factor to consider is the settlement rate of the material. In the case of clear stone, which is typically 3/4 inch in size, it’s expected to settle by around 8% after mechanical compaction. This settlement rate is relatively low compared to an alternative aggregate known as Granular A.

Granular A, on the other hand, tends to settle more than clear stone. The exact settlement rate may vary, but it’s generally higher than 8%. This means that more material will be needed initially to compensate for the anticipated settlement.

The lower settlement rate of clear stone makes it a more efficient choice in terms of aggregate usage during installation. By minimizing the amount of settlement, it ensures that you can make the most of the aggregate without having to use excessive amounts. This can ultimately result in cost savings and a more streamlined installation process.

It’s worth noting that settlement is a natural occurrence with any type of aggregate, but the extent of settlement can vary depending on the material used. Clear stone offers a good balance between stability and settlement, making it a popular choice for various construction and landscaping projects.

By understanding the differences between these materials, you can make informed decisions and ensure successful project outcomes.


In conclusion, understanding the differences between granular A and clear stone is crucial for consumers seeking effective drainage solutions. By selecting clear stone in sizes such as ⅜” or ¾”, individuals can ensure that water easily permeates through the stones, minimizing the risks of flooding or water buildup. Whether for landscaping projects or construction purposes, being aware of these distinctions allows for informed decision-making and ensures optimal results in managing water drainage effectively.
