    This new construction concrete floor was leaking ground water at a joint.  Polyurethane grout was pressure injected through mechanical packers to seal off the flow.  The grout was Hyperflex, a single component moisture activated material that is manufactured by SealGuard, Inc.  Hyperflex is pre-catalyzed and in NSF-61 approved for potable water.  The grouting was done by grouting contractor Sub-Technical, Inc.
