California-based Soil Retention is behind a product, Drivable Grass, that many of you may be interested in. The name is somewhat of a misnomer, because, as you will see below, the infill doesn’t have to be grass. It can be gravel of various kinds, too. Drivable Grass is a flexible product that can be used as a substitute for concrete and asphalt driveways, patios, parking lots, RV pads, boat ramps, and the like.
Despite the fact that we are now living in the 21st century, aerogel insulation seems like a material out of science-fiction. It is the lightest solid known, although by volume it is 99% air. It is breathable, but it doesn't absorb water. It is incredibly strong for its weight. But most importantly, it is a fantastic insulator.
InFuez, Inc., the maker of Fuez solid slab surfaces, is being mentioned more and more these days (first noticed in the Portland SIPs House). Fuez is made of low-carbon cement, curbside recycled glass, and a natural aggregate in a facility that’s 100% wind powered in Portland. Fuez can contribute to up to 5 LEED credits and can be used as tiles, flooring, or countertops. It’s a handsome product and pricing is competitive with, if not more affordable than, traditional stones and other recycled content products.
