Timber Protection Policy

Timber Protection Policy.

All our preservative treatment processes are carried out under controlled conditions in modern industrial treatment plants within the treatment centre.

The treatment process utilised depends upon the timber component and its end use. TANALITH E® preservative has a unique copper and organic biocide (triazole) formulation allowing TANALITH E® treated timber to be used where special environmental concerns or restrictions exist, as well as the everyday construction, landscaping and engineering applications for which treated timber is renowned, e.g. children’s play areas.

You may notice a green appearance on the timber this is normal on pressure treated products, this will fade in time.

All of our timber and products are vacuum pressure treated and impregnated with TANALITH E® preservative to give an expected lifespan of around 10  years.

Timber damaged by any cause other than rot or insect attack is not guaranteed.

Timber must not have been misused in any way, any on-site cutting or drilling made to the timber must be treated with an end coat preservative.

The only cost covered by this guarantee is the cost of replacement of the defective timber. Consequential expenses incurred as a result of the replacing of the timber are excluded. Timber which has been placed in abnormal conditions is excluded.

The Tanalising Process

  1. The Tanalising process involves placing the timber within the treatment cylinder and creating an initial vacuum within the timber cells.
  2. Hydraulic pressure is then applied forcing the preservative deep into the timber cells.
  3. After a pre-determined period of pressure depending on the species of timber being treated and its eventual use, the treatment solution is pumped back into storage and
  4. A final vacuum extracts any excess treatment solution from the timber.
  5. Low pressure inside the timber draws in surface solution when vented to the atmosphere and the treated timber is left for a minimum of 48hr for fixation of preservative to occur.
