Rockshield Mesh

Protectamesh HD Rockshield Mesh

For protecting damage from rocky backfill

Application Function


TERRAM PROTECTAMESH HD rockshield pipeline protection mesh is a thick, heavy duty, three dimensional bi-planar extruded diamond structured mesh manufactured from high-density polyethylene. The plastic rockshield mesh offers a consistent thickness throughout the width of each roll or pad to provide full width rock guard protection to the pipeline during and after backfill operations, by cushioning the impact of rocks which can cause damage to the pipe coating and result in the corrosion of the pipeline.

Protectamesh™ HD rockshield rock guard mesh offers high compression strength protection from abrasive objects after installation, prohibiting geologic movements from damaging your pipeline.

TERRAM PROTECTAMESH HD rockshield is flexible for easy handling, even at low temperatures, and is chemically inert ensuring that plastic mesh will not rot. The open plastic mesh design allows the flow of water around the pipe for cathodic protection.

Rock shield mesh can be installed in three methods using either ‘Longitudinal wrapping’, ‘Latitudinal wrapping’ or ‘Spiral wrapping’ and secured by means of polypropylene strapping.

  • Mesh thickness of 10mm (0.40\\\")
  • Supplied in widths 1.53m or 1.83m (5ft or 6ft)
  • Can be supplied in rolls or in pads for easy installation (cut pieces)
