Method of forming subterranean barriers with molten wax

A method of constructing an impermeable barrier comprising the steps of:

• a) directionally drilling a hole through a formation along a desired path of the barrier, and extending the hole back to the earth surface at a distal end of the hole;
• b) positioning an abrasive cable saw in the hole such that it passes through each end of the hole;
• c) positioning a pulley near each end of the hole;
• d) threading the abrasive cable saw through the pulleys to a drive means;
• e) tensioning and circulating the abrasive cable saw such that it forms a cut through the formation;
• and
• f) conveying a thermoplastic grouting material through the hole, wherein the grouting material fills the cut and facilitates removal of cuttings.
