Porous pavement is 'green' alternative to cement and asphalt

Posted:
SIOUX CITY, Iowa (KTIV) -

FilterPave has been around for a dozen years, and is used in parking lots, trails, and driveways, and patios from coast to coast.

It's also be used as road material in Europe and art projects.

Glass is mixed on site with granite chips and polyurethane, then poured like cement.

There is 47% void space, which allows rain water to filter through.

Underneath the product are layers of rock, acts as a natural cleaning system for the water.

"As the water runs through our FilterPave, contaminants latch onto the glass, and then contaminants will latch onto the clean rock under the filter pave, then the water's good to go back into the ground,” said Kevin McBee, whose company PPC contacts with FilterPave.

A topcoat prevents UV rays from breaking down the glass.

So, it doesn't crack or break, and McBee said you don't have to worry about pieces of the glass coming loose.
