University of Hawaii uses green concrete for student housing landscapes

The Univeristy of Hawaii is using pervious (permeable) concrete for the pedestrian paths in the student apartment buildings. According to Stephen Baginski of Kaikor Construction who is the contractor states that the concrete can be 10 to 20 per cent more expensive as it is more difficult to work with and can harden too quickly.
