TUFF-N-NUFF Rockshield

Tuff-N-Nuff® is a rockshield comprised of small diameter (approximately 0.050”) strands of flexible PVC which form a porous, non-woven mat. These strands are bonded to each other in a controlled random pattern during production.

Tuff-N-Nuff® protects pipeline coatings from direct impact during backfill operations. It also provides long-term protection by keeping hard objects in the backfill from coming into contact with the pipeline coating.

Tuff-N-Nuff® also protects the pipeline coating from these abrasive objects as lateral and longitudinal movements occur once the pipeline is placed into service. In addition, Tuff-N-Nuff® does not shield cathodic protection being supplied to pipelines.

Tuff-N-Nuff® is unmatched in impact resistance properties compared to other field installed rockshields.

Tuff-N-Nuff™ is installed quickly and easily in the field with no expensive equipment required.
Its flexible and light weight design was developed for cold weather conditions, making it ideal for all climates.
It is custom cut in pads or rolls specific to the pipe diameter, saving time with no wastage.
Does not interfere with cathodic protection of pipelines.
Unmatched impact resistance properties compared to other field
installed rockshields.
Eliminates the need for select fill, as the on-site native soil can be used to backfill the pipeline.
