PDS Granular Seal 50 lb. Bag

Granular Seal is a high swelling, chemically unaltered, uniformly sized (8 mesh) granular sodium bentonite which contains no additives.  When Granular Seal comes into contact with water, it forms a semi solid, gel-like mass which fills formation voids and limits water movement within the hole.  This semi solid mass also prevents surface water from following the bore hole to subsurface water supplies.
