TUFF-N-NUFF Rock Shield

TUFF-N-NUFF Rock Shield is a non-woven mat consisting of small diameter (approximately 0.050”) strands of flexible PVC. The strands are bonded to each other in a controlled, random pattern. TUFF-N-NUFF Rock Shield protects pipe coatings from direct impact during backfilling operations. It also provides long-term protection by keeping hard objects in the backfill away from the pipe coating during operation of the line. TUFF-N-NUFF protects the pipe coating from these abrasive objects as lateral and longitudinal movements occur.
