Association to Preserve Cape Cod Selects Permeable Pavement

Porous Pave XL selected for storm water management, ADA accessibility

The Association to Preserve Cape Cod (APCC) selected Porous Pave XL as the permeable paving material for the handicap parking pad and accessible walkway at their new facility in Dennis, Mass. The permeable pavement is part of the APCC’s Living Landscape Laboratory outdoor showcase of green building and sustainable landscape solutions, which also includes a rain garden and native plants replacing sections of grass. Porous Pave XL is a pour-in-place permeable paving material made from 50% recycled rubber chips and 50% kiln-dried aggregate with a moisture-cured, liquid binder.

“We are transforming a 130-year-old house and barn into our new headquarters and educational facility and creating a Living Landscape Laboratory,” said Kristin Andres, director of education and outreach for Association to Preserve Cape Cod. “With our sustainable landscaping, property owners on Cape Cod can learn about practical methods and effective materials they can use in their own landscapes to protect our unique environment.”

“Cape Cod has 1,000 freshwater ponds and more than 500 miles of shoreline. Storm water management, including permeable paving to retain storm water on site, is critical to minimize polluting runoff,” said Theresa Sprague, owner of BlueFlax Design LLC and the project’s landscape designer. “Visitors to the Living Landscape Laboratory can see how permeable paving prevents runoff. We used Porous Pave because it is slip-resistant for safe accessibility, tough and durable, easy to maintain and keep clean, and cost-effective.”

Batch mixed on site and poured directly on a base of compacted aggregate, Porous Pave XL creates one continuous rubber-rock permeable surface. Water passes through it at a tested rate of 5,800 to 6,300 gal per hour per sq ft, allowing storm water to percolate down into the base below. For durability, its recycled rubber chips give the material flexibility to withstand freeze-thaw cycles without heaving or cracking. The rubber also makes it a safe, non-skid surface. It can be shoveled or plowed in winter, and after snow removal, residual melted water permeates down through the surface rather than freezing and forming ice.

Land Escapes Design Studio, the project’s landscape contractor, poured 2 in. of Porous Pave XL atop an 8- to 10-in. base of clean angular drain rock. At only 2-in. thick, the permeable pavement can handle low speed car and truck traffic.

“Porous Pave is easy to install, sets up fast and cures quickly,” said Trevor L. Smith, lead designer, Land Escapes Design Studio. “We did the job in May 2016 with a crew of three. It took only a few hours to mix, install and finish 572 sq ft, 400 for the handicap parking pad and 172 for the walkway.”

For the APCC installation, Smith crafted a custom mix, combining Porous Pave fine-cut black rubber chips and traditional size grey rubber chips with the kiln-dried aggregate. The color and texture of the permeable pavement blend with the existing asphalt driveway on the APCC property and complement the style and color of the traditional shake shingles, which are commonly used on the exterior walls of buildings on Cape Cod.
