Polesaver Sleeves Prevent Ground Line Decay In Wooden Utility Poles

Ground line decay accounts for over 95% of wooden pole failures and is the number one cause of wooden utility pole failure.

Polesaver = Total Barrier

Polesaver Sleeves create a total barrier to all the causes of ground-line decay

Removes All Factors For Decay

Polesaver sleeves create an air and water-tight seal, excluding all factors needed for decay, making conventional ground-line decay impossible.

Easy Application

Polesaver sleeves are heat applied to wooden utility poles at the ground-line section before pole installation

What are Polesaver Sleeves?

    • Polesaver sleeves are non-toxic, composite barrier sleeves, they feature a dual-layer construction with an outer thermoplastic sleeve and an inner, meltable bituminous liner.
    • Upon heating, the liner melts, and the outer sleeve shrinks down tightly onto the pole to create a tough, air and watertight seal to the pole surface.
    • This seal permanently excludes all the factors necessary for wood decay to occur, making conventional ground line decay impossible.

Why Do Wooden Utility Poles Decay?

Ground-Line decay accounts for over 95% of wooden utility pole failures. Learn more about why it happens below

1

Preservatives Loose Effectivness

Traditional wood preservative tends to lose effectiveness over time at the critical ground-line section of the pole.

2

Repeated Wetting & Drying Cycles

This loss of effectiveness is due to oxidation and loss of chemical preservative as a result of repeated wetting and drying cycles.

3

Conditions for Decay Are Ideal

Conditions are ideal for decay at the ground-line where there is a plentiful supply of oxygen, moisture, warmth and wood-decaying organisms. These factors are not present deeper in the ground.

4

All The Required Factors

This plentiful supply creates the perfect conditions for wood decay and pole failure to occur at the mechanically critical ground line section of the pole.

Benefits Of Using Polesaver Sleeves

Polesaver Sleeves allow wooden poles to perform like concrete, steel or composites at a much lower cost

Improves Safety

Improves safety for staff who have to climb poles and the general public exposed to the potential danger of falling poles and live cables

RFID Tags Built In

RFID (Radio-frequency identification) tags with a unique electronic serial number are embedded into each sleeve, allowing easy asset tracking and management

Prevents Pole Failure

Maintains full pole strength over time thus preventing pole failure and outages in bad weather

Substantial cost savings

Polesaver gives substantial cost savings by reducing the requirement for pole inspections, maintenance and replacement

In Detail

  • Ground-line decay occurs in the upper 150mm or 6” of the ground, where all the factors necessary for decay to occur are present. These include wood-destroying fungi of which there are around 30,000 different types, wood moisture content > 25%, oxygen, nutrients and ground temperature higher than 10 C° (50F°).

  • Deeper in the ground, the temperature, nutrient and oxygen levels are generally too low for decay to occur. Above ground exposure to air drying generally ensures the moisture content of the wood is below the 25% level at which decay can start making decay highly unlikely. Above and below the ground line, wood preservatives are highly effective at preventing decay.

  • Polesaver Sleeves create a long-lasting air and watertight seal that permanently excludes all of the factors necessary for wood decay to occur. They also prevent any loss of wood preservative in the protected zone giving enhanced “double” protection over time.  The watertight seal also seals to the pole surface behind the sleeve and lowers the entry point for moisture from the ground severely limiting “wicking” of moisture up the pole. This seal ensures that the sleeve keeps moisture content below the 25% threshold at which wood decay can start.

  • Polesaver Sleeves provide total long-term protection; they make conventional ground line decay impossible, thus ensuring that decay is prevented and pole maintains its strength over time. Each sleeve is made of high quality, proven materials and is guaranteed for 50 years.

  • Termite attack of poles can be a problem in many parts of the world. Termites are generally attracted to decaying wood as this is easier for the termites to digest. By preventing decay, Polesaver has proven to be effective at significantly reducing termite attack of poles. Learn more about preventing termite attack.

How Do I Apply Polesaver Sleeves?

What Are Polesaver Sleeves Made Of?

Polesaver sleeves are a dual-layer non-toxic barrier sleeve consisting of an outer thermoplastic sleeve coated with an inner, bituminous thermoplastic sealant. There is a high performance adhesive strip to one edge to allow the sleeve to be wrapped around the pole and adhered to itself before heat application.

Inner Bitumen Sealant

The inner, thermoplastic meltable bituminous sealant is a complex blend of bitumen (asphalt) and over 20 other additives engineered to provide a durable and long-lasting seal to the pole surface. Its meltable characteristics mean that when the sleeve is heated, it melts and penetrates the pole surface, bonding the outer thermoplastic layer to the wood, creating the air and watertight seal required to prevent decay.

Outer Thermoplastic Sleeve

The outer, thermoplastic sleeve consists of a material that has a proven track record in severe ground-contact barrier applications for over 50 years.

Polesaver Sleeves Are Proven In Volume Use

Reduce Likelihood of Termite Attacks

Termites are typically attracted to decaying wood as this is easier for them to digest. By preventing ground-line decay, Polesaver sleeves reduce the likelihood of termite attack saving your poles from attack and failure in termite prone areas.

Independently Tested

Polesaver Sleeves meet the requirements of A.W.P.A. P20-18 BP1 Barrier products and have been independently tested to the following standards: A.W.P.A. E1-97, ENV 807 and EN252, all with zero decay/termite attack (full test reports available)
