Pervious concrete offers an exciting and economical alternative to traditional paving materials. Avoiding runoff and water pollution, these pavements let water pass through. Architects aiming for green projects, paving contractors looking for new markets, and homeowners planning do-it-yourself slabs gain information needed to use pervious concrete in sidewalks, bike paths, driveways, parking lots, roads, and more. Learn the hydrologic and structural design, selection of materials, placing and testing methods. Read arguments against the material as well, including their problems and defects. A glossary, reference section, and index make this an informative guide.
