Permeable Paver Driveways: Beautiful in Form and Function

Pavers: Eco Dublin®

The use of permeable pavers in driveway construction is growing exponentially across the country, particularly in areas with water use restrictions or strict stormwater management guidelines. Not only do permeable pavers boost your curb appeal, they also positively impact the environment by decreasing stormwater runoff and improving the water quality of local waterways.

Pavers: Aqualine™ Series

How, you ask? It’s ingeniously simple, actually. Permeable pavers are installed over a gradient bed of aggregate, with tiny aggregate filling the joints between each paver. As rainwater falls onto the pavers (or drains onto the pavers from another surface), the water percolates through the paver joints and down through the base materials below. There, the water is filtered by the aggregates, removing a number of pollutants before the water makes it’s way into the groundwater supply or returns to local waterways. The rising trend is to incorporate an underground cistern with a pump under the paver system so that the filtered water can be captured and recycled. A number of states and municipalities offer grants or tax incentives for these types of rainwater harvesting systems. The recycled water can be used for irrigation, water features, or other greywater uses.

Constructing a driveway with permeable pavers can also provide a number of other solutions for homeowners. For example, for steep driveways, permeable paver construction is safer during rainy weather conditions than traditional impervious surfaces, such as concrete or asphalt, because rain can permeate through pavers instead of pooling on the surface, thus improving traction.

In areas prone to heavy snow, a heating system can also be installed under the sand base of the pavers so that snow or icy rain immediately melts and drains away, eliminating snow shoveling or ice accumulation. The sand acts as a buffer between the pavers and the coils, preventing damage from any shifting caused by automotive traffic.

Belgard Provides Charm, Improved Function and Cost Savings for Playground

What happens when kids get involved in the design of a playground? Amazing things! Just ask the community surrounding Atlanta’s Chastain Park. The only public playground serving the 85,000 school-age children within a 5-mile radius, the park’s playground had not been renovated since 2000 and was in dire need of an upgrade. The existing playground had a lot of deficiencies, primarily in that it really only appealed to a small demographic (ages 5-12). The majority of the play structures were too dangerous for smaller children, yet not challenging enough for older children.

Enter play specialist consultant Cynthia Gentry, an expert in childhood development who met with school children from the surrounding community to begin the design concepts. Kids were asked to imagine what they’d like to see on the playground and put that imagery into drawings, which became the inspiration for the all of the designs.

Gentry then enlisted the help of another consultant, Robin Moore, who specializes in nature-based play, currently a strong movement in childhood development circles. Together, Gentry and Moore conducted a charrette, or meeting of the minds, with representatives from the private school located inside the park’s grounds, local public schools and pre-schools, civic associations, the Parks Commission, and various members of the community. At the charrette, the group reviewed all of the children’s drawings and synthesized them into rough design concepts. A second charrette was held at NC State to compound all of the concepts into one overall design.

Landscape Architect Bill Caldwell took the ball from there, handling permits and turning the master plan into design documents for drainage, utilities, elevation, landscaping, hardscaping, and construction of the restroom pavilion. Caldwell contracted renown water resources engineer consultant, Bill Jorden, to develop the stormwater management plan to meet all of Atlanta’s ordinances for stormwater runoff quality and quantity.

“Our goal was to not create a detention pond on a beautiful site of rolling hills and historic oak trees. I also didn’t want to have to convert the flat spaces currently used for open play. Belgard products helped us to avoid these traditional stormwater management strategies,” Caldwell said.

With the help of Belgard Urbana Stone® permeable pavers and Mega-Tandem™ Mass Segmental Retaining Wall™, the team was able to conserve land, meet the stormwater requirements, and save a significant amount of money in the process.

“Because the playground was being built into a hillside, the project required substantial retaining walls, which initially called for poured concrete. We got two Mega-Tandem Walls for the price of one poured concrete wall. Also, using the Mega-Tandem allowed us to value-engineer the pavilion and reduce the amount of poured concrete needed for the foundation. Overall, we saved over $200,000 on the project, factoring the cost savings on the pavilion and the site walls,” Caldwell said.

In addition, the 9,000 square feet of permeable paver walkways controls the amount of rainwater runoff that rolls downhill, which alleviates erosion problems. “An impervious system would have caused a concentration of water flow to the lower elevations, which would have generated more runoff than the original site,” Caldwell said.

Caldwell also notes that the Belgard permable pavers and retaining walls allowed him to create the playground out of what was formerly unusable space. “I love the fact that we took a hillside with a 12-15 degree slope that was basically non-functional and turned it into a 1-acre parkland that is a highly functional and usable space and has become a high-value component of the park,” he said. “We created something out of nothing.”

And what Caldwell considers the best part…this playgound was designed by kids for kids, regardless of age or abilities. The entire playground is ADA compliant, with multiple handicap accessible play elements. “Even the texture of the permeable paver walkway adds a sensory element for children with sensory disabilities, which is not something they would get with a smooth poured concrete sidewalk. Addressing disabilities of multiple spectrums was always part of the discussion from the beginning,” Caldwell said.

Rainwater Harvesting Now the Hottest Outdoor Design Trend

Permeable paver patios and driveways can be designed to collect and recycle rainwater. (Product shown: Eco-Dublin® pavers)

With last year’s annual survey conducted by the American Society of Landscape Architects (ASLA), green practices began to dominate the list of top outdoor design trends like never before, with 8 of the top 10 trends all related to eco-friendly or sustainable practices. With the recently released 2016 survey results, make that number now 9 out of 10, with rainwater harvesting making a giant leap up to the top spot. Take a look at last year’s trends compared to this year’s.

2015 Top 10 2016 Top 10
1 Native plants Rainwater/graywater harvesting
2 Drought-tolerant plants Native plants
3 Edible gardens Drought-tolerant plants
4 Fire pits/fireplaces Low-maintenance landscaping
5 Low-maintenance landscapes Permeable paving
6 Permeable paving Fire pits/fireplaces
7 Water-efficient irrigation Edible gardens
8 Rain gardens Rain gardens
9 Lighting Water-efficient irrigation
10 Rainwater/graywater harvesting Reduced lawn area

These trends reflect consumers’ growing commitment to landscapes that reduce water use and stormwater runoff, says Nancy Somerville, Hon. ASLA, executive vice president and CEO of ASLA.

“Water issues are hot topics for many communities, and many people are turning to landscape architects for creative green infrastructure solutions,” said Somerville. “Sustainable residential landscape architecture, if part of a broader integrated site design, can dramatically reduce water usage and stormwater runoff over the long term while creating a healthy residential environment.”

With a combined rainwater harvesting permeable pavement system, Belgard offers a way to combine three of these top outdoor design trends with a single design element. With this type of pavement system, rainwater drains through the joints between pavers and percolates down through a bed of gravel into a collection cistern, where a pump can recycle the water for irrigation or water features. Pollutants are removed from the water as it drains through the gravel, which adds additional protection for the environment.

Many municipalities and states offer grants and tax incentives for installing either permeable pavers or a rainwater harvesting system, which is likely a factor in the growing popularity of using permeable pavers for this purpose. With the variety of attractive Belgard permeable pavers available, homeowners can build stunning outdoor living areas, driveways and walkways that are as ecologically responsible as they are beautiful.

Tips for Keeping Your Cool

With triple-digit heat indexes spanning the lower half of the country, many people are now scurrying indoors to avoid the heat, forced to enjoy their beautiful outdoor living spaces from the comfort of the kitchen window. However, there are a number of design tips and tricks that can alleviate some of the heat and allow you to get more use from your outdoor living spaces during those dog days of summer.

Advantages of Pergolas

A pergola can provide multiple design benefits for an outdoor living space. The open-air aspect allows for unrestricted air movement while still defining the space to visually create the look of an “outdoor room”. Additionally, the structure itself both filters the direct sunlight and can provide the framework for a outdoor-rated ceiling fan. To provide additional shade and add to the visual interest, flowering vines — such as Wisteria or Morning Glory — can be trained to grow atop the pergola.

Outdoor Living Structures

The benefit of a roofed structure, as opposed to an open-air pergola, is that it provides a little more protection from the elements, including both sun and rain. Although late afternoon sun and driving rain will still creep in, you’ll still have increased shelter, as well as additional opportunities for fans, lighting, audio/visual equipment and appliances.

Made in the Shade

There are a variety of affordable products available that can help increase the amount of shade in your outdoor living space, particular during that unbearably hot time of the day when the sunlight comes in at just the right angle to make you feel like you can fry an egg right on the patio flooring. Attractive options include indoor/outdoor curtains, retractable solar shades, and colorful sun canopies.

Permeable Paver Water Features

Particularly in hot climates with lower humidity, water mist can significantly reduce the ambient temperature of a localized outdoor area. An alternate option to a traditional water-misting system is to install a water-recycling permeable pavement system that incorporates a water feature. The paver system can collect and recycle rainwater and provide a fun activity for kids, all while releasing mist into the air that will help alleviate some of the oppressive heat.

Anyone who has children and/or dogs knows that muddy pathways around your home are a huge problem for the interior of your house. Muddy footprints (and paw prints) can make keeping your home clean a monumental task. As a mom of two boys and a dog, I can tell you that our yard was a big mess of bare pathways, and frequently that mess was tracked indoors.

Several homeowners before us installed rounded landscape timbers and pea gravel to stop the inflow of mud into the home. Unfortunately as the timbers rotted, the gravel spread outside the frames. In its place, a congregation of weeds sprang up. Frankly, I think the weeds were enjoying themselves more in our backyard than we were. It was embarrassing to invite friends to a weed-filled jungle with rotted timbers dotting the landscape. We longed for a backyard that was devoid of messy pathways, and was a usable space for entertaining. This past Autumn, we decided a plan needed to be implemented to solve our landscape woes.

dublin-cobble-front-walk2Several years ago, we had a Belgard pathway and circular patio installed near our front door. We love the look of those pavers. The Dublin Cobble® has an old world feel, and the color variation between the pavers gives them the look of old tumbled pavers. I watched the landscaping crew install the Universal Circle Kit and was amazed by how quickly and easily the pavers fit together. To us, Belgard has always stood for quality landscaping hardscapes.

After the plans were drawn for our backyard, choosing the brand to use for hardscapes was easy. Deciding on the pavers and wall blocks was more difficult because of the large variety of Belgard products to choose from. In the end, we were able to merge formal and informal areas easily. The hardscapes complement the style of our house and look like they’ve been here for decades.
