To ensure long term performance from all our gate timbers, they are preservative treated as standard in our on site treatment tanks, although untreated timbers can also be supplied, if required.

Within our pre-treatment operation we utilise the latest generation, environmentally advanced timber preservative – TANALITH® E.

This renowned preservative gives a proven, outstanding performance, particularly for timbers intended for use in ground contact applications.

TANALISED® E treated timbers have an initial pale green colouration which slowly weathers to a warm honey brown and, in the longer term, to a natural silver grey.

Treatment Process

  • Timber loaded into treatment vessel. Initial vacuum applied and the timber cells are evacuated of air. Vacuum held.
  • Cylinder flooded under vacuum withTANALITH® E wood preservative.
  • Hydraulic pressure applied, forcing the
    preservative deep into the structure of the timber.
  • Final vacuum extracts excess preservative solution, which is pumped back to storage.
  • Low pressure
    inside timber draws in surface solution when vented to atmosphere. Treated timber is left to dry.

Bond Timber is an approved TANALITH® E treater for Sector Scheme 4 Treatment NHSS Standard. We are also able to manufacture gates to the H21, H22 and H23 specification.
