Tanalith Family

High-pressure preservative treatments for building, fencing, landscaping and engineering timbers.

Timber is the most versatile product nature has to offer. However, it can also be vulnerable to the effects of the weather, wood decay and insect attack. High-pressure preservative treatments extend the service life of timber, giving real confidence in its long term performance.

Timbers treated with TANALITH wood preservative can be used with confidence in both above-ground and in-ground situations including construction, fencing, landscaping and engineering applications.

Latest generation TANALITH wood preservative is applied in a controlled, high-pressure industrial process within our own treatment facilities. It leaves the resulting TANALISED treated timbers with an initial pale green colouration that blends into any outdoor environment. Over time the TANALISED treated timbers slowly weather to a warm honey-brown colour and eventually to a natural silver grey.


Vacsol Family

Low pressure preservative treatment for general construction and joinery timbers used above damp proof course level.

Timbers treated with VACSOL wood preservative have an envelope of protection, through a proven low pressure, the double vacuum application process in our own treatment facilities.

VACSOL preservative provides proven protection against decay and insect attack organisms ensuring an extended service life performance from the VACSOL treated timbers.

The short treatment cycles for VACSOL ensure minimal dimension change to these fine tolerance timbers.

VACSOL treated timbers have a virtually unchanged appearance. However, we add a pale yellow colour to our process as a visual confirmation of treatment.
