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.
