Pressure Treatment Process

Pressure Treated Timber

Protected by a unique, highly developed preservative formulation, pressure treated timber gives a reliable and consistent protection against fungal decay and insect attack.

Built into the latest preservatives are patented and award-winning technologies which deliver even more consistent and effective preservative penetration into the timbers, and an even more assured, long term protection for all treated timber end uses.

Appealing natural pale green colour with excellent weathering properties.

Usually specified for indoor and outdoor applications where there is a medium to high risk of fungal decay and insect attack, eg. general construction, landscaping and leisure timbers, fencing, garden buildings and other outdoor timber projects.

High Pressure Preservative Treatment Process

The pressure treated timber is impregnated with a preservative under controlled conditions by vacuum high pressure technology in an enclosed system.

The solution is a water based wood preservative that contains copper and proven organic biocides. When impregnated into the timber the preservative components bond with the wood structure and cannot easily be removed.

The pressure treated timber has a long-term protection against fungal and insect attack, including termites, for both in and out of ground contact, interior and exterior applications when treated to the correct end use specification.

Pressure treated tanalised timber has an initial natural green colouration. Upon external exposure, the green colour slowly weathers to a warm, honey brown and in the longer term becomes a natural silver grey. This weathering process does not indicate any loss of preservative protection.
