Polesaver sleeves are a patented dual-layer barrier system that is independently tested and proven to exclude all the factors required for wood decay.

Our sleeve’s dual-layer, full barrier technology is the key to increasing pole life by +20 years from the start

How do they work?

  1. Polesaver sleeves are non-toxic, composite barrier sleeves. They feature a dual-layer construction with an outer thermoplastic sleeve and inner thermoplastic liner.

  2. 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.

  3. This air and watertight seal permanently excludes all the factors necessary for wood decay to occur, whilst also preventing loss of wood preservative. Polesaver’s dual-layer technology makes conventional ground line decay impossible.

Substantial Cost Savings

Polesaver sleeves are low in cost; they give substantial cost savings by reducing the requirement for inspections, pole remediation and replacement.

Improves Safety

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


Based on independent EN252 field test data, Polesaver Sleeves are proven to increase pole life from the start.

Ground line decay means that typical wooden pole loses strength over time and once below the 50% strength threshold; pole replacement will be required.

Sleeves make conventional ground line decay impossible, thus adding +20 years to the pole life from the beginning.

Our sleeves are the only proven and independently tested the product on the market that ensures pole strength is maintained over-time at the critical ground line section, improving safety and grid reliability.

Used with DCOI wood preservative, Polesaver is a proven alternative to using Penta (Pentachlorophenol) preservative, giving an assured increase in pole life of 20 years or more.
