Des Plaines Alleyways: Filtercrete Pervious Concrete
Des Plaines Alleyways | Filtercrete™ Pervious Concrete

Approximately seven years ago, due to the proximity to the Des Plaines River, the City of Des Plaines was in need of alleyways that could handle the excess stormwater to fight flooding, without causing added issues due to freezing in the winter months. The city contacted Ozinga to learn more about our Filtercrete™ pervious concrete that allows water to filter through the concrete and make its way back into the ground.

During this partnership, Ozinga assisted with an upgraded pervious concrete alley design, which differs from the City of Chicago alley design. The Des Plaines alleys are full-width pervious concrete with concrete curbs on either side. This creates a larger pervious surface that requires less frequent cleaning.

"Ozinga Filtercrete™ is at the forefront of pervious concrete technology in terms of mix design, program rules for installation, and pervious system designs."

During implementation of the alley program through the years, Ozinga has created improved formulas for the Filtercrete™ pervious concrete designed primarily to improve resistance to de-icing chemicals. The Des Plaines alleyway project used the most recent formula, which includes extremely durable stone that is sourced in Canada and an improved concrete paste recipe. Both of these products have shown improved resistance to de-icing chemicals that are routinely applied to roadways for safety, but which chemically and physically attack concrete pavements, especially pervious concrete pavements.

Ozinga Filtercrete™ is at the forefront of pervious concrete technology in terms of mix design, program rules for installation, and pervious system designs, including the FilterStar system that uses Filtercrete™ as a base for porous pavers. The Filtercrete™ and  FilterStar system have been copied across the country as communities search for viable stormwater solutions. The Filtercrete™ mix has been a template for other mixes, and the FilterStar system has been used to virtually eliminate the settlement problem endemic in porous paver systems. By replacing the middle layer of aggregate with pervious concrete, the pavers remain as flat and stable as the day they were installed, and trip and fall problems from settled pavers become a thing of the past.
