Grid-Guard HD Plus

Description

Grid-Guard HD Plus is a high-strength 11mm (3/8”) polyethylene pipeline protection grid engineered with an integrated 6-oz non-woven geotextile backing for enhanced durability and performance. This advanced pipeline protection solution safeguards both steel and plastic pipelines from impact damage during backfill and provides an extra layer of protection after burial.

The geotextile backing acts as a slip sheet, reducing soil stress on pipeline coatings and preventing damage caused by shifting soil and rock movement. The three-dimensional diamond mesh structure provides consistent thickness, lightweight flexibility, and superior impact resistance, ensuring long-term protection without interfering with cathodic protection systems.

Product Benefits

• Superior Impact Protection – Withstands impact from rocks and backfill debris; tested to ASTM G13 and G14 standards with no failure under 6″ rock drop tests.

• Added Geotextile Layer – Heat-laminated 6-oz non-woven backing minimizes soil stress and acts as a durable slip sheet around the pipe.

• Cathodic Protection Compatible – Does not shield or interfere with CP systems, maintaining full corrosion protection.

• Enhanced Durability – Provides consistent 11mm (3/8”) protection thickness and exceptional compressive strength (90 psi @ 50% deformation).

• Lightweight and Easy to Install – Flexible mesh design allows rapid installation in rolls or pads with minimal labor.

• Custom Sizing Available – Offered in rolls up to 6 ft wide and pads for pipelines 24 inches or larger, with a recommended 6″ overlap for secure coverage.

• Field-Proven Performance – Independently tested for high impact strength (141.7 in-lbs per ASTM G14).

Typical Applications

• Pipeline Backfill Protection – Shields fusion-bonded epoxy, polyethylene, and tape coatings during burial.

• Soil Stress Reduction – Minimizes mechanical stress caused by ground movement.

• Large-Diameter Pipelines – Used as protective pads for 24″+ diameter pipe sections.

• Oil, Gas, and Water Infrastructure – Suitable for energy transmission and utility pipelines in harsh or rocky terrains.

• Pipeline Rehabilitation Projects – Ideal for use during recoating or reburial operations.
