Erecting the earth fills on a weak base is an old and sufficiently well researched problem. However, every time new approaches, methods and concepts are found with respect to it. Even ancient Incans and Aztecs used to use vine shoots (fascine) to strengthen the base of the structures and to negotiate marshes and bogs. Since times immemorial in Russia woven birch bark has been known to help travel through the impassable places. Many things have changed in the modern world but the basic principles and approaches to reinforcement have remained the same. It is true that today instead of fascines, birch bark and vine shoot weavings, they use the reinforcing flat geo-lattices and geo-fabrics, whose breaking strength ranges between 10 and 240 tons per linear meter.
