GREENVILLE, AL – Airports are reducing pavement maintenance costs and providing better runway, taxiway, parking and fueling areas with E-KRETE® Long-Lasting Overlay (PCMO®). The cementitious polymer overlay is impervious to aviation gas and jet fuel, reduces surface temperature by 15° F to 30° F in sunlight, and protects asphalt from sun and water damage.
Travis Capps, Sr., airport manager of Mac Crenshaw Memorial Airport, reports that E-KRETE® overlay used in their approximately three acre parking and fuel service area is saving money on pavement maintenance, and making the parking and service areas cooler for pilots and passengers.
“We have a lot of military helicopter traffic that touches down in our parking area,” Capps said. “We get some gouges from the skids. Before the E-Krete® application, these gouges led to deterioration of the asphalt. The E-Krete® Overlay is hard. It doesn’t deteriorate around the edges of the gouges.”
Capps also reported that E-KRETE®, which is impervious to aviation gas and turbine fuel, has stopped damage from the small amount of fuel some turbine engines release while starting.
The Greenville Airport’s 150,000 sq. ft. parking and fueling area, and the 5,000 ft. runway were resurfaced with asphalt as thick as eight inches in 2000. In 2001, the parking and fueling area where protected with E-KRETE®. No maintenance has been required on the parking and fueling area. However, the runway has been resurfaced with asphalt seal coating twice, and is due for more maintenance.
“Prior to applying E-KRETE®, the wheels of light, single engine airplanes left tire indentation marks on the hot asphalt,” Capps said. “Today we handle jet airplanes as large as Challenger 600s and Gulf Streams. They leave no trace on our parking pavement, even on the hottest days.”
E-KRETE® Long-Lasting Overlay has been used since 1998 at facilities serving general aviation, airlines, NASA and the United States military. Applications include airports in Corpus Christi, and Zapata, TX; and the International Airport in Melbourne, FL. Many installations on parking lots and private roads that are over 12 years old have required no maintenance. It is cold applied and cures 1 to 1½ hours to minimize traffic interruptions. The SR version reduces surface temperatures 15° F to 30° F in sunlight. It contains no hydrocarbons. It is tested and approved by the U.S. Army Corps of Engineers. In many cases, its life cycle cost is lower than asphalt and its periodic maintenance. It is manufactured by PolyCon®USA, LLC.
This E-KRETE® protected asphalt parking and fueling area at Mac Crenshaw Memorial Airport has required no maintenance since 2001 and remains in good condition.
In the same time period, the use of the airport’s unprotected asphalt runway has been interrupted twice for maintenance with seal coating.
Logan, UT – In the Cache Valley, a land where extreme beauty is matched by extreme weather changes, Utah State University makes its buildings high tech to control heating and cooling costs and provide the best environment for learning and research. Now the university is moving to control the costs of parking lot maintenance while also making its parking lots more attractive, safer, brighter at night, cooler in the daytime and more environmentally friendly.
“Sunlight and weather – temperatures can range from -20° F to 101° F – aren’t the only enemies of parking lots in this area,” said Quin E. Whitaker PE MBA, structural engineer/project manager. “High traffic including trucks that empty dumpsters, pushing snow, scraping ice, huge piles of ice and snow that stand for months, salt, water from melting snow and ice in the winter combined with almost unlimited UV exposure in the summer create parking lot maintenance costs we are reducing with new technology just as we are using technology to reduce operating costs of our buildings. A year ago we embarked on a program to make our parking lots better, less expensive to maintain, and more environmentally friendly. We are beginning to see results.”
"Over the 2011-2012 winter, the university tested a cement and polymer paving preservative product to see how it stood up to the extreme conditions, especially the ice and snow removal equipment," Whitaker said. "Results were good so the university moved forward this summer using E-KRETE® Long-Lasting Overlay (PCMO®) to preserve a 27,000 sq. ft. parking lot."
Manufactured by PolyConUSA, E-Krete® is a proprietary cementious polymer composite micro overlay that is approved by EPA, NASA, US Army Corps of Engineers, is accepted by the FAA for airport use, exceeds the solar reflectance index for LEED® project certification and is NCAT proven. Many E-KRETE® sites continue to provide an attractive appearance after 12 or more years, with no sealing or resurfacing.
Whitacker said replacement of the university’s asphalt parking lots cost $300,000 to $500,000 per year for the past six years. On-going yearly maintenance such as striping, painting, crack sealings, and resurfacing alone total in the neighborhood of $50,000 to $100,000 per year. “We don’t want to put our money into pavement maintenance year after year,” Whitaker said. “Our initial test showed we could stop much of this maintenance expense with E-KRETE®.” He said the 27,000 sq ft lot repaired and preserved with E-KRETE® Long-Lasting Overlay and striped with E-KRETE® Long-Lasting PermaStripe® consisted of both fairly new asphalt and fairly old asphalt.
“We already see a big difference. Because of our severe weather we had been hesitant to place much faith in overlays of any type. However, we feel that E-KRETE® has the performance and track record that we are looking for to fill our needs.”
For the first time in years, snow removal equipment did no damage to this Utah State University parking lot. It was protected by E-KRETE® Long-Lasting Overlay during the 2012-2013 winter.
“We had no damage from ice and snow, and no damage from the heavy snow removal equipment used to clear it as we kept the lot open and safe throughout the winter,” said Quin E. Whitaker, PE MBA, the University’s structural engineer/project manager. “The E-KRETE® protected pavement exposed to temperatures this winter as low as -20° F , 24 inches of snow and constant traffic from snow and ice removal equipment pushing the snow and ice with heavy-duty plows that scraped along the surface as often as three times a week.”
E-KRETE® is a cementitious polymer formulation developed to reduce parking lot maintenance costs, protect the environment and make parking lots more attractive and safer. Applications as old as 12 years show no significant damage and have required no seal coating or resurfacing. "Protection of asphalt parking lots is part of the university’s effort to reduce maintenance and operation costs with both buildings and pavement," Whitaker said.
“Sunlight, heat, snow, ice, salt, and especially snow removal equipment can damage asphalt pavement year after year,” said Tom Bender, Chief Executive Officer of PolyCon®USA, LLC, manufacturer of E-KRETE® LONG-LASTING PRODUCTS. “E-KRETE® protects against these problems. It saves money because it is durable and doesn’t need periodic seal coating and asphalt resurfacing. In addition, it is environmentally friendly because it contains no hydrocarbons to escape into the atmosphere or ground water, and seals the asphalt to prevent hydrocarbon leakage. It is also cooler in the hot summer sun (15° F to 30° F cooler in sunlight than asphalt) and brighter at night.”
E-KRETE® Long-Lasting PermaStripe®, also a cementitious polymer formulation, was used to stripe and mark the University’s E-KRETE® parking lot. Whitacker reported that there was no winter damage to the E-KRETE® Long-Lasting PermaStripe®.

ORANGE BEACH, AL USA – The spectacular fishing and cruising boats docked at Orange Beach Marina in this Gulf Coast vacation spot aren’t the first thing that catches the eyes of boat owners and visitors. The first thing is the marina’s parking lot and the attractive marina buildings that surround it. Top notch maintenance has made the marina one of the most successful on the Gulf Coast.
Although not as flashy as the pleasure boats, the marina’s parking lot is attractive in its own way. The surface is smooth and comfortable, and safe to walk on with its built-in abrasiveness, 15° F to 30° F cooler under the hot Alabama sun, bright at night, unaffected by rain (with no hydrocarbon runoff into the nearby waterway), immune to the stains and delamination caused by automotive fuels and lubricants, and resistant to the corrosive effects of salt air. It’s an introduction to the quality facilities and services offered by the marina. “A 33,000 sq. ft. section of the parking lot has been protected by E-KRETE® Long-Lasting Overlay for about seven years,” said Bennett Long, the marina’s General Manager. “It shows no signs of wear while our other, much larger, parking lot is nowhere near that old and needs resurfacing.
"We have done no maintenance on this lot for seven years,” Long said. “Our maintenance savings on this lot is $78,375.” Long said the marina will resurface its other parking lot and its roadways with E-KRETE® Long-Lasting Overlay this year. “Our other lot and road ways are over 100,000 sq ft,” Long said.
“Adding in the road ways we are anticipating three times the savings as we eliminate all continuous seal coating and asphalt resurfacing as well as environmental problems that come with it. But just as important, all of our parking lots and roadways will reflect the quality of our facilities and services. They are literally the first thing people see when they drive into the marina.”
The marina’s manager attributes some of the marina’s success to the attractiveness of its E-KRETE® Long-Lasting Overlay parking lot as well as the money the lot saves on maintenance.
CHICAGO, IL - The 2.13-mile streetscape that’s the greenest in Chicago preserves rainwater as a resource rather than turning it into a waste product, as it also demonstrates that environmentally better practices and products can be less expensive than traditional products.
The Chicago Department of Transportation’s Comprehensive Sustainable Streetscape Project is on Cermak Road, a major thoroughfare that connects the neighborhoods of Chinatown, Pilsen and a warehouse district along the south branch of the Chicago River. The project incorporates storm water Best Management Practices (BMPs) and uses environmentally friendly “green” techniques commonly associated with LEED® project certification but not typical in streetscape designs.
E-KRETE® Long-Lasting Overlay (PCMO®) was selected for use in preserving asphalt in the curb lane because it is solar reflective and lowers the surface temperature 15° F to 30° F compared to asphalt in sunlight, and is brighter at night allowing the use of street lights selected for energy efficiency. E-KRETE® also has the economic advantage of eliminating the cost of continuous seal coating and resurfacing that makes it appealing for commercial applications such as parking lots.
E-KRETE® is a proprietary cementitious polymer composite micro overlay that is approved by EPA, NASA, US Army Corps of Engineers, is accepted by the FAA for airport use, exceeds the solar reflectance index for LEED® project certification and is NCAT proven.
E-KRETE® overlaid asphalt applications more than 12 years old have not required the asphalt resurfacing and sealing that is standard practice every few years with asphalt alone. In addition to cost savings, elimination of these maintenance operations has the added benefits of less interruptions to parking traffic and less hydrocarbons released, and less materials used.
“The economic benefits of E-KRETE® make its environmental benefits inexpensive to obtain,” said Tom Bender, Chief Executive Officer of PolyCon®USA, manufacturer of E-KRETE®. “In parking lot applications, it is saving $112,200 for a national retail outlet and $74,375 for an office building, by eliminating the need for continuous seal coating and resurfacing with asphalt.”
Only result was some slight scuffing of the sand laying on the surface.
