Porous Pave LOT42 Global Flex Campus

Porous Pave was a good choice for permeable paving. It is not only permeable, its recycled rubber content makes it a green material
— Patrick Doyle, Marketing Partner LOT42
LOT42, the Innovative Events Space in Canada’s Waterloo Region Technology Hub, Meets Stormwater Management Requirements with Porous Pave

LOT42 Global Flex Campus, a performance venue and events complex in Kitchener, Ont., installed 12,400 square feet of permeable pavement using Porous Pave XL. LOT42  is a 17-acre global flex campus dedicated to arts, technology, manufacturing, athletics, and community events. Distributed in Canada by Porous Pave Ontario (Stratford, Ont.), Porous Pave XL is a highly porous, pour-in-place permeable paving material made from 50 percent recycled rubber chips and 50 percent kiln-dried aggregate mixed on site with a liquid binder.

The result of a multi-million dollar transformation of an old industrial site originally developed for Ardelt Industries of Canada in 1955, the LOT42 event complex blends the area’s manufacturing heritage with modern style. To meet the City of Kitchener’s stormwater control regulations, the project incorporated several elements of green infrastructure, including a 1,000-square-foot French drain and a total of 12,400 square feet of permeable pavement, installed with Porous Pave. 

“With 27 percent void space, Porous Pave can infiltrate 5,800 gallons of storm water per hour per square down into the underlying aggregate base,” said Jim Roth, president, Porous Pave Ontario (Stratford, Ont.). “It can endure freeze-thaw cycles, frost and ground movement without heaving and cracking, an important advantage with our winter weather in Ontario.”

Zehr Interlock & More (Tavistock, Ont.) was the project’s installation contractor. Kris Zehr and his crew installed the 12,400 square feet of Porous Pave, poured in place at a depth of two inches, on a three- to five-inch base of compacted aggregate. “Including LOT42, we have done 20 Porous Pave projects. As a pour-in-place material, it has proven to be much easier and much faster to install than pavers,” Zehr said. “It also gave us the flexibility to create a custom green-tan color mix, which we alternated with the standard green color.”

“We like the appearance, and are impressed with the results. There is no more water ponding in front of the entrance, and it eliminated water infiltration into building,” said Doyle. “We are planning to add more permeable pavement in the courtyard area with inlaid designs created by Porous Pave Ontario.”
