Percoa USA has developed and patent pre-cast pervious concrete. Pervious concrete is engineered with an open-cell structure to allow rainwater to drain directly through its entire surface, so the water can percolate down into a stone aggregate substrate and then infiltrate into the soil. In the issued patent, US 2012/0018363 A1 (published on July 8, 2014) Percoa received broad protection for its unique, innovative pre-cast pervious concrete system and methods as well as related water filtration systems for stormwater management.

"We have demonstrated the durability of Percoa pre-cast pervious concrete as well as its effectiveness in capturing and filtering runoff," said Brett Pomerleau, founder and president of Percoa USA, LLC. "Now that we have secured our patent, we are moving forward to license our technology to companies ready to manufacture pervious slabs and pavers for stormwater management in commercial and residential applications."

Pervious concrete controls and reduces stormwater runoff at the source, improves water quality by decreasing erosion and filtering out pollutants, and recharges groundwater supplies. The Environmental Protection Agency recognizes it as Best Management Practice. A land planning and engineering methodology, LID emphasizes natural features integrated with engineered hydrological controls to capture and clean stormwater runoff on site.

"Percoa has the potential to revitalize and expand the use of pervious concrete," said Mary Vancura, Ph.D., civil engineer, Beton Consulting Engineers. "With Percoa, you know what you are getting, and how it will perform, because of its controlled production process."

The performance of Percoa pre-cast pervious concrete has been proven in a wide variety of successful installations. Since October 2011, the Minnesota Department of Transportation has monitored an installation of Percoa slabs at MnROAD, a sophisticated, independently operated pavement test facility.

According to MnDOT, to date, the test slabs have withstood three winters of freeze-thaw action and an estimated 720 tests with the weight of a fully loaded 18-wheel, 5-axle tractor trailer with little settlement or cracking.
