The use of structural soil is relatively new technology, and is not completely passed the experimental stage yet. It is evolving and advancing today. To be established as sound technology, structural soil needs more precedents and post evaluation over a longer time span. These three key points; 1) regional/local adaptability of soil specifications, 2) long term effects, and 3) strategy to lower the cost, contain key information to increase the use of structural soils in the future.
