    In such soils the efficiency of SVE is often reduced due to airflow bypassing areas of relative low permeability. Problems of flow bypassing are the subject of this study. In the present work a new venting technique, pneumatic venting, is proposed as an alternative to conventional soil venting, when dealing with restoration of layered soils.
