Sometimes it’s the little things that make all the difference—such is the case with permeable paver grit. Standard permeable paver grit comes in ¼” x ⅛”, and the question is how does something so small make such a big difference in landscaping and construction? Permeable paver grit has numerous benefits for the environment, your budget and your project. View our selection today!

What Is Permeable Paver Grit Made of?

Let’s get down to the nitty-gritty of permeable paver grit. The permeable paver grit at Kafka Granite is comprised of over 40 different types of crushed granite and quartzite available in a palette of colors to match your project – the most popular being Starlight Black, Caramel, and Colonial Red.

Our granite and quartzite aggregates are extremely hard materials that easily withstand the rigors of even the most extreme freeze/thaw cycles. Unlike softer aggregates, such as limestone, our granite and quartzite will not break down and clog your runoff system over time, ensuring maximum drainage for many years to come.

The Role of Permeable Aggregates

Permeable paver grit is made to seamlessly fit between permeable interlocking concrete pavement, also known as PICP. Our aggregate fills the spaces between paver blocks or bricks, which not only adds to your design’s appeal, but it also creates an optimal drainage solution for your project. If you want to avoid harmful stormwater runoff, optimal permeability is key.

Permeable paver grit is an eco-friendly way to optimize the drainage of any project. Permeable paver grit helps reduce stormwater runoff as well as replenishes groundwater reserves. Stormwater can collect and carry harmful pollutants when it settles on the ground, but the permeability of this material helps stormwater seep through the surface of the ground, allowing it to be naturally filtered. This means less stormwater runoff reaches and contaminates our lakes and streams.

How Stormwater Runoff Affects Us All

In the past, contractors and landscapers might have used marbles or limestone as a paver grit but we now know that this can prove to be detrimental to both your project and the environment. By using softer materials like limestone, you run the risk of getting clogged joints over time as your materials break down. Clogged joints cause your expensive commercial permeable pavers to not perform the way they were intended.

In a natural setting that has been left undeveloped, trees and vegetation break the momentum of rain, which in turn helps with erosion and helps filter the stormwater before it reaches larger bodies of water. After the stormwater has been filtered by vegetation, it is drained into streams that then transport the now filtered runoff to large bodies of water. But what happens after land has been developed? Runoff collected from developed areas commonly contains pollutants from cars, fertilizers and other chemicals.

Here Are the Most Common Pollutants that Stormwater Can Pick up:

• Oil, grease and coolant from automobiles
• Fertilizers
• Pesticides
• Bacteria from pet waste and septic systems
• Soil from uncompleted construction sites
• Soap from cars or equipment washing

Biggest Concerns from Unmanaged Stormwater Runoff:

• Pollutants from stormwater contaminate our waterways and kill off fish and wildlife. This in turn has the power to close local businesses that depend on a source of locally caught fish.
• When too much water is accumulated and rushes to streams and other drainage systems due to a lack of permeability, it can lead to flooding.
• When water is kept from reaching the ground naturally, a water shortage can accumulate, which affects the entire community and ecosystem.

Permeable Paver Grit Paired with Decorative Precast Pavers

Kafka Granite does not directly produce precast pavers, but we take pride in providing speciality aggregate and permeable paver grit used in these designs. Our aggregates are sourced from throughout North America. The raw materials are then transported to our crushing facility in Central Wisconsin to ensure the highest level of quality control possible. We then sell our aggregate to the leading paver manufacturers in the country, all of which produce permeable pavers.

Kafka Granite offers nearly 60 different colors of natural stone and recycled materials in any size. Our aggregates can be found in pavers coast to coast. Kafka Granite’s crushed granite, marble, quartz and recycled materials can be used in decorative precast pavers and a broad assortment of amenities such as precast concrete water fountains, trash bins, snuffers, planters, tables, benches, columns, chairs and more.
