When installing Perma Plug above carbon backfill, insure complete backfill settling before beginning Perma Plug installation.
· Condition the earth hole area to be sealed by flushing with clean water or by allowing any drilling fluids to sufficiently thin by overnight settling. The fluid within the earth hole should allow the Perma Plug particles to sink readily.
· Pour Perma Plug slowly into earth.
· Install one 50 lb. bag of Perma Plug every 3 to 4 minutes until the desired level is obtained.
Once in place, Perma Plug will expand to seal the earth hole.
Perma Plug will completely seal earth holes when applied properly. It is strongly advised to utilize a vent pipe for the release of gases and as a facility for water addition if needed. The AllVent breather pipe is recommended. Specifically manufactured for deep cathodic protection systems, AllVent stays open and does not plug with backfill.
