Outdoor Organic Bonding Sand
EnviroSand from EnviroBond is a stabilized joint sand for redoing driveways, walkways, and patios. It combines traditional jointing sand and an organic glue made from a renewable plant resource and designed to form an adhesive gel that binds sand particles with water. When spread among paving stones, the formed gel protects the sand from washing away and creates a toxic environment to prevent weeds from sprouting, according to the company.
