Tanasote® is an oil-based copper wood preservative that has been developed for high performance, industrial timbers, such as railway sleepers and utility poles. A modern alternative to Creosote, Tanasote® has been specifically designed to minimise early failures whilst providing a long service life.

Based upon an innovative combination of organic biocides and copper in a mobile oil formulation, Tanasote® S40 has Biocidal Products Regulation (BPR) authorisation across Europe. The oil-based wood preservative achieves a high penetration depth into the timbers, with excellent water repellent properties for improved stability in service.

A New Choice for High Performance Timbers

To demonstrate efficacy for extended service life in heavy duty applications we have invested in durability testing which goes beyond those required by EN standards. We have also engaged in a number of commercial trials across fencing, railway sleepers and utility poles.
