MAXIMISING THE LIFECYCLE OF CRITICAL ASSETS
Polesaver Rot-Guard™ Sleeves are a proven, total barrier product which protects wooden utility poles from the damaging effects of ground-line decay.

Our innovative, eco-friendly barrier reduces moisture and prevents fungal growth, maximising pole lifespan and reducing maintenance costs. Easy to apply and built to withstand harsh environmental conditions, Rot-Guard™ Sleeves provide proven protection against rot and significantly reduce the likelihood of termite attack, ensuring infrastructure remains secure and cost-effective for years to come.

WHY CHOOSE ROT-GUARD™?

80% of wooden utility pole failures are due to ground-line rot.
Polesaver Rot-Guard™ sleeves protect this vulnerable section of the pole, safeguarding vital infrastructure.
+20 Years From The Start
Polesaver Rot-Guard™ sleeves add 20 years to the life of the pole at the point of installation, no matter what wood species or type of preservative is used, with no loss of strength for 40 years.​
Substantial cost savings
Rot-Guard™ sleeves are competitively priced and offer substantial cost savings through maximising the life of the pole, reducing the requirement for inspections, pole remediation and replacement.
Improves Safety
The application of a Rot-Guard™ sleeve ensures poles maintain strength, this improves safety for inspection teams, and for the general public.
Supports CSR Goals
Wooden utility poles with Rot-Guard™ sleeves applied offers the lowest carbon footprint of any pole option. Rot-Guard™ sleeves are non-toxic and environmentally friendly. They lock in vital preservatives and reduce ground contamination by up to 97.5%.

RFID Built In As Standard

All Blaze-Guard™ sleeves feature RFID (radio-frequency identification) tags as standard, making asset management easy.

THE EVIDENCE

Based on independent EN252 field test data, Polesaver Rot-Guard™ sleeves are proven to maintain utility pole strength over time.
Ground-line decay means that a typical wooden pole loses strength over time and, once below the 50% strength threshold, pole replacement will be required.

Rot-Guard™ sleeves make conventional ground-line decay impossible, with independent testing proving they add 20 years to the life of a pole from the start.

Based on utility-sponsored testing, Rot-Guard™ is the only proven and independently tested dual-layer barrier product on the market. The test data proves that sleeves ensure pole strength is maintained over time at the critical ground-line section, improving safety and grid reliability.

EASY APPLICATION IN ANY LOCATION

On-site training, application videos, and an easy-to-use product combine to make Polesaver Rot-Guard™ barrier sleeves a natural choice whether applying them on-site, in the field, or at a pole yard.
Wrap Around
Polesaver Rot-Guard™ sleeves are non-toxic, composite protective barriers designed to wrap securely around the ground-line section of a wooden utility pole.
Heat Apply
When heated, the inner liner melts while the outer sleeve shrinks tightly onto the pole. This process forms a durable dual-layer, air and watertight seal that securely bonds to the pole surface.
Activate Dual-Layer
The dual-layer air and watertight seal permanently blocks all factors that contribute to wood decay, while also locking in preservatives.
