Postsaver, who are make sleeves used as wooden post preservers say that as a Europe-wide creosote ban approaches, their products have been proven to be the best way of preventing rot.
In a new test report, published by Freedom, part of NG Bailey and a provider of technical engineering and maintenance services, shows that preservative treated samples all suffered loss of strength after decay testing whilst the preservative treated samples protected with Postsaver sleeves did not lose strength clearly demonstrating the effectiveness of total ground line barrier sleeves.

The study had been commissioned to examine the best Creosote alternatives for wood post preservation in light of the Creosote ban coming into effect in Europe.

Approved for funding by Ofgem under the Network Innovation Allowance Scheme, the test is an extended accelerated fungal decay test which generally has good correlation with real life performance. In the study, three commercially available wood preservative options are compared:

  • Creosote with and without barrier sleeves
  • Tanasote (copper in oil) with and without barrier sleeves
  • RVP, a copper in oil formulation, tested with and without barrier sleeves

The results of the test showed that treating the stakes with preservative and applying a  Postsaver barrier sleeve prevented loss of strength over time.

Postsaver sleeves are non-toxic, composite barrier sleeves. They feature a dual-layer construction with an outer thermoplastic sleeve and inner thermoplastic liner. This air and watertight seal permanently excludes all the factors necessary for wood decay to occur, whilst also preventing loss of wood preservative. Postsaver’s dual-layer technology makes conventional ground line decay impossible.
