Management of Optimum Design and Construction on Landfills

Assessment and investigation of soil and bedrock properties is of an essence for construction of residential, commercial as well as industrial complexes. In order for the foundation system of such projects to be opted, it is necessary to assess the geotechnical characteristics of the site. In many p...
