What is DigBarrier™?

DigBarrier™ is a passive mechanical protection barrier installed above buried assets to intercept excavation forces before direct contact with the facility occurs.

Manufactured from High-Density Polyethylene (HDPE), it is designed to either survive impact events or sacrificially fail while preserving asset integrity. Both outcomes are acceptable — provided the asset remains protected.

DigBarrier™ does not rely on power, sensors, monitoring, or human activation. Its protective function is inherent to its physical presence.

Product Line

PG1 / PG2 / PG3 / PG4

Four modular components — covering every trench geometry and application scenario.

PG1
1,200 × 1,000 mm
Standard Module Main trench coverage — square geometry. Primary protection module for most applications. Connect multiple PG1 plates to cover any trench length.
PG2
1,200 × 500 mm
Half Module Transition coverage and edge applications. Used at trench ends, utility crossings, and where full PG1 width would extend beyond the asset zone.
PG3
1,200 × 250 mm
Quarter Module Tight spaces, angular runs, and congested corridors. Also used to complete coverage at trench transitions where fractional width is needed.
PG4
Anchor Pin System
1 Anchor Plate + 2 Locking Pins Used to secure the protection system in the installation configuration.

✓ Recommended Scenarios

Where DigBarrier™ adds value

Urban and peri-urban utility corridors with frequent excavation activity
Shallow or variable depth-of-cover installations
HDD entry/exit transition zones
Utility crossings and congested corridors
Post-repair backfill — minimal cost addition at point of exposure
Rights-of-way subject to repeated disturbance
— Not Required

Where it is not warranted

Deep transmission corridors with controlled access
Rural or low-activity zones with minimal third-party excavation
Greenfield projects with strictly controlled depth coverage
Locations with existing equivalent mechanical protection

"Risk-based deployment — not blanket installation. Selectivity preserves credibility and ensures resources are directed where residual risk is genuinely unacceptable."
