Abstract

A process for improved hydrophobic waste storage is described wherein a latex comprising a preformed, high molecular weight polymer having a high affinity for hydrophobic liquids, is sprayed on the waste prior to admixing an inorganic matrix material. Alternately, a liner for use in a waste pit which is to contain hydrophobic waste liquids or concentrated aqueous salt solutions is produced in situ by blending and compacting a latex comprising a hydrophobic polymer and clay onto the surface of the waste pit.
