PIONEERING; research and Development
Environmentally acceptable pole preservatives. The BPS permits preservatives previously unsuitable for ground contact conditions to now be used for pole protection. Of particular relevance in this context are water-soluble formulations of environmentally-benign but unfixed preservatives such as boron and quaternary ammonium salts.

Decay prevention. The BPS laminate is also impenetrable by fungi and termites therefore the product’s second function is to prevent colonisation of a protected pole by decay agents from the soil, although this is a strictly secondary function since the BPS in any event maintains the toxic threshold of a pole’s preservative at the intended level (or at augmented levels described above) which decay agents cannot overcome.

Maintenance of toxic thresholds. The BPS laminate is impervious to moisture and all volatile organic molecules, which in turn renders it resistant and impervious not only to water-borne pole preservatives such as CCA, but also to the oil-borne preservatives pentachlorophenol and creosote. The primary function of the BPS is therefore that it prevents loss of preservative to the soil, which in turn maintains the toxic threshold of preservative in the ground contact region of the pole.

SPECIFICATIONS - Augmentation of preservative levels. Since mobile pole preservatives such as creosote are prevented by the BPS from absorption by the soil that surrounds protected poles, the preservatives instead accumulate in the butts of such poles. They accumulate by soaking into the previously-untreated interiors of the poles and thereby increase preservative penetration in the subsoil zones – i.e., in the most hazard-prone zones - of protected poles.
INSTRUCTIONS FOR USE AND INSPECTORS' GUIDE
Cost savings. The use of BPS increases pole service life by eliminating remedial treatment and premature failure. Cost/benefit analyses show that the crossover point in savings accrued through BPS-usage by owners of large pole inventories occurs at 5 – 7 years, whereafter the accumulated savings increase exponentially.
