Project: Pervious Alleyway - Evansville, IN
Customer: City of Evansville, IN
Contractor: Deig Bros Construction
Project obstacles and solutions: The City of Evansville was having problems with storm water backing up and flooding the alleyway behind a residential neighborhood. Since trash pickup happens down this alley, the combination of standing water and trash was causing a bad odor and was a public health concern. Deig Bros Construction was hired to reconstruct the alley with pervious concrete to quickly drain the storm water.
The alley was redesigned with a subgrade of stone over a geofabric. The stone was placed at a depth of 16-1/2 inches to hold the water until it percolates back into the ground. The surface was finished with with two strips of broomed concrete flanking a center strip of imix Eco Pave pervious concrete placed 3-1/2 feet wide x 7-1/2 inches deep. By using imix Eco Pave, the water is channeled to the aggregate subsurface and any floating contaminants are trapped in the porous concrete.
The alleyway is flood free and odor free. For more information on imix Eco Pave and the benefits of pervious concrete, click here.
