The solution is a simple protective sleeve, which is easily fitted and meets international environmental requirements.
Biotrans scientists have developed and patented Field Liners. A simple and elegant solution
that prevents the failure of both untreated and preserved poles in soil.
Acting as an inert physical barrier, they prevent pole failure and protect the environment.
Four years after installing poles with Field Liners on an electrical distribution line, no leaching of creosote
or microbial decay was found. However, as expected, the Field Liners caused the creosote to be
concentrated in the pole sub-soil regions, providing added protection. (a case study)
In contrast, H4 poles without Field Liners leached their creosote, leaving them substandard at H3
levels and incipient decay had already started. (see below.)
