Where building takes place on sites covered by substantial depths of waste material, geotechnical problems may arise and are likely to be associated with long-term settlement of the fill. The loadcarrying properties of the different types of fill that form such waste deposits vary greatly and thorough investigation is needed, preferably including a programme of field tests. Where the loadcarrying characteristics of a waste fill are found to be poor, the use of an appropriate ground improvement technique, prior to construction on the site, may form an economic solution to foundation problems.
