Most standard barrier systems micro-crack and have no activity, especially the ability to neutralize acid. A solution we have seen in the field is to use a chemically active alkaline coating (acid neutralizer) near the interface and then cover the wet coating with tar paper if immediate back-fill is required to protect the coating from the dirt, concrete or asphalt. Cheap and quick but addresses the problem with the right chemistry.
