Using Unilock at Navy Pier: A Kafka Granite Case Study

Kafka Granite has been supplying aggregates to some of the country’s largest remodels and revamps for years. From the Brooklyn Bridge Park in Brooklyn, NY to the Erin Hills Golf Course in Hartford, WI, a wide range of Kafka Granite products can be found at some of the country’s most popular attractions. Such attractions include the Buckingham Fountain, Yankee Stadium, and Chicago’s Navy Pier. The Navy Pier project was one of Kafka Granite’s crowning achievements. Through hard work, determination, and collaboration with Unilock, Kafka Granite was able to help the city of Chicago restore their historic landmark.

Navy Pier was first opened in 1916 and has seen millions of visitors since. Most recognize Navy Pier by it’s glowing ferris wheel and lively family-friendly entertainment. In 2016, to celebrate the Pier’s 100th birthday the city of Chicago decided to give the beloved destination a makeover. The goal of the project was to preserve the history and integrity of Navy Pier while making it more eco-friendly and ensuring its longevity for future generations. Navy Pier is a massive venue with over 50 acres of stunning lake front property. When city officials began researching ways to revitalize this historic landmark they knew that whatever products they decided to utilize would have to withstand hot Chicago summers, wave barrage from Lake Michigan, and the harsh winters that cover the Midwest every year.

Kafka Granite has a long history of creating green alternatives that can be utilized in a variety of applications. Some of Kafka Granite’s eco-friendly projects include the white roofing materials and decomposed granite mixtures. However, one of the most common ways Kafka Granite can help projects attain a LEED or SITES certification is through the use of their recycled aggregate blends, and the Navy Pier project is a perfect example. Through a partnership with Unilock, Kafka Granite was literally a key ingredient in restoring one of America’s most iconic landmarks and achieving the prestigious SITES Gold Certification through GBCI.


Renovations began in 2013 in order to be complete for Navy Pier’s 100th Anniversary in July 2016. The project was awarded Sustainable SITES Initiative (SITES ) Gold Certification in November 2016.


Navy Pier needed to cover the entirety of the 50-acre pier with a high quality, yet aesthetically pleasing, concrete pavers. In the eyes of the design team responsible for the Pier’s redesign, the pavers needed to act as an organizational device that could help inspire the design aspects of the other areas of the Pier’s new design and serve as the fabric that tied the entire redesign together as a whole. The new pavers made in partnership with Unilock and Kafka Granite can be seen on the tree-lined South Dock Promenade, as well as the expansive and newly developed Polk Bros. Park and Fountain.


James Corner Field Operations ultimately won the competition that the Navy Pier was holding to choose their next design firm. James Corner Field Operations then decided to partner with Unilock. Unilock is a leading manufacturer of interlocking precast concrete pavers. Unilock knew that they needed to partner with a local, regional aggregate provider to create the pavers that the James Corner Field Operations were looking for, and Kafka Granite was a natural fit.


James Corner Field Operations, the company who won the right to lead the redesign of this historic landmark, needed a paver that could function in a variety of settings. For this project, the paver ultimately chosen needed to work in areas of heavy-duty pedestrian and vehicular traffic, and in areas that were designated as heavy-duty vehicular roadways. Additionally, certain areas needed to be permeable to help direct rainfall away from the storm sewer systems and back into the natural ecosystem. If that weren’t enough, James Corner Field Operations had a few additional qualifications when it came to choosing their winning paver.

  1. The company who provides the paver must be able to provide support for the lifetime of the project
  2. Pavers must meet SITES certification standards
  3. Pavers must be comprised of at least 30% recycled content
  4. Pavers must come from and be manufactured from within the region
  5. Any aggregates used in the pavers must be regionally extracted
  6. Pavers must have a high SRI value


The vision of the leading-edge landscape architects at James Corner Field Operations (JCFO) was brought to life in part due to an innovative partnership between Unilock and Kafka Granite. One major goal of the Navy Pier’s redesign was to establish an area that was less commercialized and more focused on uniting green space and people. The first challenge of this project was buried in trying to expand the desired green spaces and improve pedestrian access while concurrently improving stormwater management and using recycled materials in an effort to have the project SITES certified. Due to the Pier’s proximity to lake Michigan, all care and consideration had to be put forth into the design and development of the runoff system for the Pier’s vast 50-acre surface area.

Kafka Granite and Unilock responded to the call and rose to the challenge of creating this new urban oasis landscape while remaining environmentally conscious by creating a one-of-a-kind Navy Pier collaboration. As the nation’s premier manufacturer of concrete interlocking pavers, Unilock was an obvious partner when it came to creating a gorgeous surface for the improved landmark. In order to meet the rigorous specifications JCFO established for materials to be used, Unilock teamed with Kafka Granite to create a solution that would check all the boxes mentioned above.

Kafka Granite’s recycled copper slag was an imperative part of the Navy Pier redesign puzzle. With Kafka providing recycled crushed aggregate to Unilock, specifications were precisely met while environmental needs were surpassed. Not only was a portion of the pavers permeable, which will aid in stormwater management, but their clever incorporation of recycled materials made this project’s SITES Gold certification possible. In total, 30% of the materials used for the entirety of the redesign were made from recycled content.

Kafka Granite has been incorporating sustainable processes and products into the aggregate industry for years. From its state-of-the-art crushing facility to its use of recycled porcelain, kiln slag, copper slag, firebrick, glass, mirror, and more, Kafka Granite is a company that understands the importance of reducing, reusing and recycling. By using recycled copper slag that would have otherwise found its way into a landfill, Kafka made it possible for Navy Pier, and various other projects, to achieve highly a sought after SITES certifications. Not only will the Navy Pier’s new design have a positive effect on the city of Chicago, but the gold certification acquired using Kafka Granite recycled aggregates rendered the redesign to be the first project to earn such a pristine level of eco-friendliness under SITES v2 requirements. Kafka Granite looks forward to helping many more companies and project become eco-friendly and be awarded green certifications in the years to come.

Eco-Friendly Permeable Paver Grit in Chicago

Creating green environments—especially in urban areas—is on the rise. From the installation of a new solar panel project every two minutes to the emphasis on reducing carbon emissions, people are focused on reducing energy consumption and helping the environment for a greener tomorrow. Cities today are faced with the challenge of meeting the needs of urban dwellers as well as trying to foster an eco-friendly future. One way to help the environment is right beneath our feet.

Permeable pavers and permeable paver grit help reduce stormwater runoff as well as replenish groundwater. The permeability of these pavers and corresponding crushed aggregate between pavers means that stormwater—which can collect and carry harmful pollutants with it—can seep through the surface of the ground and be naturally filtered as it passes. The encouraged absorption of this rainwater also means that nearby rivers and lakes are less likely to be subject to pollutants and flooding.

Chicago Going Green with Permeability

Nearly 2.7 million people are living in the urban jungle dubbed Chicago. With that many people creating carbon footprints and siphoning energy, any push toward a greener tomorrow is a good one. Check out some of Chicago’s greenest grounds: Buckingham Fountain Plaza, Loyola University and the Metropolitan Correctional Center.

Buckingham Fountain

The pavers making the expansive plaza surrounding Chicago’s infamous Buckingham Fountain uses Kafka Granite’s aggregate between pavers. Our Sunset Pink permeable paver grit perfectly complements the aesthetic of this historic fountain and landmark while providing the green solution fit for Chicago’s eco-conscious efforts.

Permeable paving in Chicago is most effective in areas closer to Lake Michigan because they’re underlain with sandy permeable soils—which makes Buckingham Fountain the perfect place for a permeable paver grit solution. Kafka’s expansive color variety enabled the paver grit to be a  beautiful compliment to the unique Unilock pavers in this setting, as well as be the most functional solution for a permeable plaza.

Loyola University

loyola university chicago

Loyola University of Chicago is home to more than 16,000 students. When it came to grounds solutions, permeable paver grit was the go-to for this project. Used as fill between Permeable Interlocking Concrete Pavement, Kafka’s Mauve permeable paver grit (PPG) provides ample stormwater drainage. Our quality materials also easily stand up to high volumes of foot traffic and the grueling freeze/thaw cycles of a Midwestern winter. With Kafka’s aggregate as Loyola’s permeable grit, they won’t have to worry about the grit breaking down or clogging their runoff system.

Metropolitan Correctional Center

pavers at metropolitan correctional center

The Metropolitan Correctional Center was opened in 1975 and stands as a looming 28-story federal prison in the thick of Chicago’s downtown. While this may seem unusual, the prison as a whole fits into the architectural backdrop of the city. With a sleek combination of modern and urban design, complementing the design was important when it came to the surrounding plaza. The MCC’s unique landscape design called on using both Kafka’s Platinum Granite PPG and Wausau Tile’s permeable pavers. What’s more, our standard platinum granite pathway material was used throughout the patio area in order to allow for maximum drainage around the trees.

Superior Permeability with Kafka’s Superior Quality

Our state-of-the-art crushing facility can create permeable paver grit to match your exact sizing needs or standards. Plus our impressive variety of color options, nearly 60 colors in all, means you can find the paver grit to perfectly complement your paving project. The importance of a high-quality PPG that is properly sized for your project cannot be stressed enough. Opting for softer materials, such as marbles and limestones, leaves you at risk for clogged joints as those materials will break down with time. Similarly, a grit that is too small defeats the purpose of a permeable design as it will compact too densely and not allow for optimum drainage. If you’re paying a premium for permeable pavers, make sure to get the most out of them with the right PPG.

Thinking about permeability in your next project is important for the environment. By allowing stormwater to move through pavement, you minimize the risks associated with stormwater discharge. According to Wisconsin’s Department of Natural Resources, permeable pavers and permeable paver grit:

  • Promote stormwater infiltration, groundwater recharge, and stream baseflow preservation
  • Reduce the discharge of stormwater pollutants to surface waters
  • Reduce stormwater discharge volumes and rates
  • Reduce the temperature of stormwater discharge

The importance of permeability in ground-cover solutions is especially important when protecting nature from harmful pollutants, which keeps our cities like Chicago beautiful places to live and visit. Plus, permeable solutions can earn you points toward LEED certification for your project. To hear more about the benefits of Kafka’s permeable paver grit, contact us today. Our experts can answer any question you may have and can help with your project.

WHITE IS THE NEW GREEN: White Roof/Cool Roof Epoxy Overlay

LEED Credits With Kafka Granite

Since 2000, LEED Certification has served as the industry standard for measuring a building’s environmental sustainability. LEED, standing for Leadership in Energy and Environmental Design, is a way to establish and recognize a building as a “green” or eco-friendly structure or project.

Kafka Granite offers an incredible amount of products that could help your new or old construction project get acknowledged as green and receive one of four levels of LEED certification: certified, silver, gold or platinum.

From energy-efficient options such as white roofing aggregates to recycled materials like crushed porcelain or glass, Kafka offers repurposed and all-natural solutions to be used in a variety of ways. We can also help ensure architects are selecting regionally specific aggregate in order to achieve Regional Priority Credits. Since some of Kafka’s products are sourced from around the nation, it’s critical to ensure you’re getting materials that fulfill “geographically specific environmental priorities” in order to garner LEED credit for RPCs. To learn about all the ways Kafka materials can be used in your project and get it closer to LEED certification, talk to us today.

Why should your project be LEED-certified?

LEED certification will reap different incentives depending on which state your project is in. Not only will an impressively sustainable or eco-conscious build garner media attention or community support from those who appreciate green efforts, but they could also receive tax credits or fee reductions/waivers among other things.

Eight different green aspects of a building are taken into account:

  • Sustainable Sites
  • Location and Transportation
  • Water Efficiency
  • Energy and Atmosphere
  • Materials and Resources
  • Indoor Environmental Quality
  • Innovation
  • Regional Priority

Depending on the type of the project, there are 110–136 credits that can be earned. The more credits earned (the more criteria fulfilled) will translate to a higher LEED-certification level: 40–49 credits for certified, 50–59 credits for silver, 60–79 credits for gold and more than 80 credits to achieve platinum certification.

“Using more green materials, including renewable materials, recycled materials, and natural materials, is good for the building occupants and the environment.” Using organic or recycled materials from Kafka Granite can earn a project more points toward a higher level of LEED certification.

Is being LEED-certified more expensive than not building with recycled/natural materials?

Aiming to build a LEED-certified project, according to this study, will only initially cost as much or slightly more than a project not building with recycled or natural materials. However, the benefits and incentives gained from LEED certification may likely outweigh or outearn the extra construction and materials costs paid up front.

By working with Kafka Granite on your next LEED-certified project, you will get the best possible natural or recycled materials — such as our expansive variety of decomposed granite, crushed aggregate, and recycled materials — to aid in your green initiative.

Custom Firebrick Blend Stabilized Pathway Cart Path – Whistling Straits Golf Course – Kohler, WI

Due to popular demand, Recycled Fire Brick Blend is back! As part of Kafka Granite’s sustainability initiative, Kafka recycles several landfilled materials or waste products such as porcelain, glass, mirrors, slag, and now–fire brick. These products can be used in place of natural aggregates for a more environmentally-friendly design.

Recycled Fire Brick Blend consists of a beautiful array of warm oranges and golds, due to the various colors of fire brick used by Kohler Corporation in their kilns during the production of porcelain toilets and sinks. Rather than wasting away in a land fill, Kafka collects this material and carefully crushes it to size for use in standard, stabilized, and wax polymer pathway mixes–giving the fire brick a new life.

In the past, Recycled Fire Brick Blend had been so popular that Kafka had depleted Kohler’s land fill– a good problem to have! However, we have now inventoried enough of the product to introduce it back to the marketplace. Want to help us clean up the landfills?

Kafka Granite Paves Way for Sustainability

Investing in sustainability and eco-friendly ventures is costly. Despite the obvious and necessary environmental benefits, the sheer price tag of going green prevents many businesses from making this ecological leap. Kafka Granite, a family owned small business, has found an impressive number of ways to bear its eco-conscious muscle and help the environment despite its size.

In addition to offering decomposed granite aggregate solutions, which are an inherently environmentally friendly alternative to asphalt or concrete, Kafka Granite offers a broad portfolio of other green solutions, such as white roofs and permeable paver grit. Thinking outside of the granite box, Kafka has even teamed up with several other businesses in efforts to recycle waste product such as porcelain, glass, mirror, firebrick and slag.

Decomposed granite is a natural product and is the result of granitic rocks being weathered and eroded. Although organic stabilizing binders can be added and the aggregate is compacted, the permeability of decomposed granite aggregate perseveres. Beyond natural decomposed granite, many other eco-friendly hardscape solutions are becoming popular. In addition to supplying manufacturers with aggregate to create permeable pavers, Kafka Granite also specially produces permeable paver grit, the joint filler between the pavers.

An added benefit of Kafka Granite’s permeable paver grit is its ability to complement the pavers’ color or design. It can be practically camouflaged or can lend itself to the aesthetics of the area while providing the appropriately sized joint filler. Using the correct size, and hardness, of aggregate between pavers ensures that joints between pavers won’t become clogged and the permeability of the joints will remain optimal during its lifespan.

The incredible permeability of Kafka’s aggregate prevents water runoff or unwanted flooding — instead, the water permeates the aggregate and is reabsorbed by the soil and water table below. Ancillary benefits of Kafka aggregate include its lifespan — requiring fewer replacements than alternatives.

Some of Kafka’s aggregates are manufactured for other environmental causes such as white roofs. Also known as cool roofs, Kafka produces recycled porcelain and white quartz which can be applied to pre-existing rooftops using a two-part epoxy overlay. Naturally round Birchwood granite is also available for traditional rooftop ballast applications. White roofs diminish the heat island effect — the occurrence of higher temperatures in urban areas versus rural ones — exhibited by dark roofs. By reflecting the majority of the sun’s rays, the ambient temperature surrounding a white roof is dramatically lower. The cooling costs of a structure with a white roof are also reduced, saving costs for homeowners, business owners, and the atmosphere.

Kafka Granite Recycled Copper Slag

As a Wisconsin-based company, Kafka looked to native-Wisconsin businesses Wausau Tile and Kohler Corporation to join in a recycling initiative. Kohler Corporation’s rejected porcelain toilets and sinks, as well as the corporation’s other landfilled materials like slag and firebrick, get crushed to size and used in place of natural stone. Recently adopted was the recycling of glass screens from outdated televisions and computers, as well as two-sided mirrors. Recycled materials can be used as aggregates in precast concrete, terrazzo flooring and countertops, epoxy overlay surfacing, pathway materials and more. The smoky recycled glass serves as an impressive alternative to expensive natural quartz, while the two-sided mirror creates a unique, high-end finish to flooring and countertop products.

Using recycled and sustainable materials helps architects earn points toward LEED certification. LEED, Leadership in Energy and Environmental Design, was created by the U.S. Green Building Council and serves as third-party verification to determine whether new construction is truly green or eco-friendly. By using sustainable materials or recycled products manufactured by Kafka, designers and architects can establish themselves as leaders in green design and construction — a highly sought after quality in modern construction trends.

Kafka Granite's Dust Collection System

Kafka Granite’s Dust Collection System

Even the byproducts of Kafka’s manufacturing process are reused. Taking an eco-friendly leap forward, a state-of-the-art dust-collection system was installed at Kafka’s crushing facility. A huge asset, the system winds through the crushing facility, acting like a large vacuum and collecting dust. This innovative system not only keeps otherwise wasted dust from polluting the air, but after it has been collected, it is being reused in the creation of other products such as pathway mixes.

Kafka’s sustainable efforts aren’t only rooted in the core of the business through the sustainable and recycled product offering, but these efforts branch into big-picture efforts to increase efficiency, reduce its carbon footprint and look for solutions to aid in a greener future. Even its less-noted efforts, like using secondhand pallets for shipping, accumulate to create a more sustainable tomorrow and serve as an example for how even small businesses can aid in the green movement.

Pathway Materials

For pathways, bike paths, and other trail systems where a more natural look and feel is desired, consider a more organic material that is both aesthetically appealing and durable.  Sometimes traditional concrete or asphalt just won’t do. The Standard Pathway Mix is made from decomposed granite or crushed stone, screened to a specific size to ensure a maximum compacted surface that retains firmness, flexibility, and permeability.  Kafka also offers two additional levels of durability. The Stabilized Pathway Mix includes an organic binding agent for a stronger, more stable, and less erosive surface.  Meanwhile, the Wax Polymer Pathway Mix is the best pathway solution for extremely high traffic areas or steep inclines, as it’s non-permeable surface allows water to bead off the surface, eliminating mud, dust, and erosion.

Ballyard Materials

Finding the proper materials for baseball or softball diamonds can be a nightmare; most of the traditional materials are too muddy, too dusty, and too high maintenance, which all take valuable time away from both the groundskeepers and players. However, Kafka Granite specializes in low maintenance, high drainage products that minimize mud and dust, while retaining the natural playing surface that players know and love. From standard high-drainage top dressings, to high-quality, professional grade infield mixes and warning track mixes, Kafka Granite offers a variety of solutions for any price point: from the little league to the major league.

WHITE IS THE NEW GREEN: White Roof/Cool Roof Epoxy Overlay


Kafka Granite’s White Roof Aggregates help reduce the Heat Island Effect:
Finally! Summertime is here and the sun’s getting hotter. Throughout the nation, temperatures are on the rise. However, did you know that the annual mean air temperature in cities can be 1.8 to 5.4°F warmer than its rural surroundings? According to the United States Environmental Protection Agency, this difference can be as drastic as 22°F in the evening. This anomaly, referred to as the heat island effect, is a result of the dry, urban surfaces, including pavement, rooftops, and other infrastructure, that replaces the natural landscape and vegetation as cities are developed. However, there is a solution that can help offset this heat island effect.

Cool roofs are being developed with both a high solar reflectance, or albedo, and a high thermal emittance. Together, these characteristics allow the surface to absorb less heat, keeping the roof up to 60°F cooler than traditional roofing materials. These roofs assist in reducing energy costs, air pollution, and greenhouse gas emissions, while increasing human health and comfort due to decreased air temperatures.

While cool roof products have been developing over the last twenty years, Kafka Granite’s White Roof Aggregates are suitable for both new and preexisting roof tops! Kafka Granite specially produces both Crystal White Quartz and Recycled Porcelain aggregates and manufactured sands in a variety of sizes suitable for use in several application techniques of white roof coating. Kafka Granite’s White Roof Aggregates can be quickly and easily applied to any preexisting rooftop using a two-part epoxy. While our Crystal White Quartz is a brighter white, our Recycled Porcelain can help increase the LEED points earned on your project.

Do you want to reduce energy costs, air pollution, and greenhouse gas emissions in your metropolitan area? Kafka Granite aggregates can help! Contact one of our knowledgable sales representatives to receive more information or to request complimentary samples.
