Porous Plus: Eco-Tek Pavers Include Regional Slag

The pavers can be tinted with EnvironOxide pigment, an iron-oxide-based byproduct of soil remediation in areas with excessive runoff from abandoned coal mines. According to Lampus’s vice president for marketing, Bob Welling, “We also have the ability to use some percentage of recycled materials as an aggregate constituent, in place of sand and gravel.” Welling said that standard concrete pavers cost about $4/ft
