Finally the project engineers for Nature Trails used for hiking, jogging, cycling, roller bladeing, skate boarding, golf course paths, river bank walkways etc. have found a way to build a smooth surface for such uses by a river's edge that will ensure a solid permanent foundation to lay the flat asphalt on that is guaranteed not to sink or deteriorate. This great new structurally sound and economical pathway was just built connected to a busy traffic freeway, across a scenic golf course and along a river bank which presented no problem once the EarthZyme base was constructed.
