Geotechnical Lightweight Fill

            
   Lightweight aggregate  fills are approximately half the
    weight of common fills.  This advantage, coupled with
    its predictable high internal friction angle, can also
    reduce lateral forces by more than one-half.  It has been
    effectively used to solve numerous geotechnical
    engineering problems and to convert unstable soft soil
    into usable land.
    Lightweight fill also provides permanent non-degradable
    insulation around water lines and steam lines,  and other
    thermally sensitive elements.  Expanded shale, clay and
    slate lightweight aggregate,  ESCS, is a reliable and
                                                                            economical geotechnical solution.
