Geotechnical Lightweight Fill

Utelite expanded shale (ES) 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. Utelite ES Lightweight fill also provides permanent non-degradable insulation around water lines and steam lines, and other thermally sensitive elements. Utelite ES is a reliable and economical geotechnical solution.
