The construction of clay liners for landfills

Abstract

Correct liner installation is fundamental to the construction of a containment landfill. The significance of material properties and the requirements of field placement and compaction are presented. The principle of demonstrating by means of construction quality assurance (CQA) that a mineral liner has been placed in accordance with the design requirements is discussed. Procedures are reviewed and the technical requirements of a landfill project that appertain to the CQA work are outlined. aterial CH J MH CV J MV CE "/~ / / / ME 0 20 40 60 80 100 120 LL (%) Fig. 1.
