Tanasote®…. The most effective alternative to creosote treatment with 25 year guarantee.
Tanasote®
This relatively new treatment is a modern hot oil-based wood preservative containing copper and innovative organic co-biocides designed specifically to protect high performance heavy duty timbers and deliver a service life of 40 years plus, whilst minimising the risk of early failures.
Developed and manufactured by Arxada, Tanasote® was approved in March 2021 under the Biocidal Products Regulation (BPR) Authorisation Process. It has been granted the maximum 10 years authorisation, passing all necessary environmental, human and animal health risk assessments. It is the only oil-based wood preservative that has this authorisation.
