Grid-Guard HD Plus | Pipeline Protection
An 11 mm polyethylene protection grid with a heat-laminated 6 oz non-woven geotextile backing, built to protect steel and plastic pipe coatings from rocks and debris during backfill.

Product Overview
Grid-Guard HD Plus pairs a rigid diamond-pattern polyethylene grid with a 6 oz non-woven geotextile that's heat-laminated to its back. The grid takes the hit from rocks and backfill debris, while the geotextile spreads the load, reduces soil stress on the coating and acts as a slip sheet when the ground moves.
It's light and flexible enough for crews to wrap quickly with minimal labor, and its open structure won't shield your cathodic protection system. Use it over epoxy, polyethylene and tape coatings on oil, gas and water lines, for new construction or rehab and recoating work.

Why Crews Choose It
Engineered to keep pipe coatings intact from the trench through final backfill.
01
Tested to ASTM G13 and G14: no failure in rock drop testing and 141.7 in-lbs of impact strength.
02
A heat-laminated 6 oz non-woven layer reduces soil stress and works as a slip sheet against ground movement.
03
The open grid does not shield CP current, so your corrosion protection keeps doing its job.
04
A uniform 3/8" profile with 90 psi compressive strength at 50% deformation.
05
At just 0.45 lb/ft², the flexible mesh deploys quickly with minimal labor.
06
Rolls from 24" to 72" wide, plus pre-cut pads for pipe 24" in diameter and larger.
Applications
Used across oil, gas and water infrastructure, wherever rocky backfill puts pipe coatings at risk.
Shields epoxy, polyethylene and tape coatings from rocky, abrasive backfill and burial debris.
The geotextile layer cushions the coating and acts as a slip sheet when the soil shifts.
Pre-cut pads sized for 24" and larger pipe make quick work of big lines.
Protects freshly applied coatings on rehabilitation and recoating projects before burial.
