Timber Treatments

As part of the manufacture of all our fencing and landscaping products ETC Sawmills preservative pre-treat our timbers within our own on-site facilities using latest generation TANALITH 9000 wood preservative from Lonza Wood Protection to ensure the resulting next generation TANALISED timbers will have a greatly extended and low maintenance service life. As a minimum all our timbers are treated to a 15 year desired service life specification.

When it comes to preservative pressure treated timber, you need to have assured confidence in its long-term performance and durability.

The TANALISED pressure treated timber we supply is unique. It has been treated with latest generation TANALITH 9000 wood preservative - an exceptional and proven product, which provides unrivalled protection for your timbers.

More than 20 years of successful commercial use, in addition to extensive independent field trials, underpin the performance of TANALITH 9000 wood preservative.

Next generation TANALITH 9000 has all the properties of the original TANALITH but also now incorporates patent pending BARamine technology from Lonza Wood Protection. This provides an even more robust protection allowing greater penetration of the wood preservative into the timber as well as protecting against certain copper tolerant brown rot organisms.
