TUFF-SEAL, which comes in both a fine and coarse grind, is a blend of sized carbonic materials which are highly resilient in nature. TUFF-SEAL allows the tightly packed particles under compression in pores or fractures to expand or contract without becoming dislodged with changes in differential pressure.
