Why Tanasote®?

A Modern Alternative to Creosote

Creosote has a long history in successfully protecting high performance heavy duty timbers, such as railway track timbers and utility poles, against the threat of decay or insect attack. However, from a regulatory point of view, its safety and environmental credentials have been under severe review for quite some time, especially in Europe and the UK.

Like any other product, wood preservatives need to evolve with changes in the market place. Looking at how we can continue to enhance the durability of wood as a sustainable resource, we have developed Tanasote® timber technology  – a hot oil based wood preservative containing copper and innovative organic co-biocides. Purposely designed to deliver a service life of 40 years plus*, whilst minimising the risk of early failures, Tanasote® is a new choice for high performance, heavy duty timbers.

Why choose Tanasote?


*Depending on commodity, desired service life, timber species and application, service life requirements can vary. For more information on service life of different commodities please contact us.

Trust in Performance

The testing of wood preservatives is a well documented procedure, covering both laboratory and field testing. To prove real world performance in the most demanding of environments, Tanasote® has been subject to additional testing in copper-tolerant field test sites as well as laboratory fungal studies. Testing of water-repellent properties has also been undertaken.
