SP Pavers provide ecological benefits in the prevention of storm water runoff. With an infiltration rate exceeding 1 gal/sec/sq. ft, the pavers allow storm water to flow through while filtering out gross pollutants. Only 12 to 15% of total surface coverage is required for unparalleled drainage capabilities, allowing the pavers to be utilized with impervious surfaces for a cost effective solution. SP Pavers are also an instrumental component with the Xeripave Filtration Tray System. The system is designed to protect both leach fields and/or main storm drain inlets by filtering out 100% of gross pollutants. The pavers then leave behind all the sediment and urban clutter resulting from storm water runoff.
