Creosote Impregnation
For over 20 years Timber Preservation Technologies have designed built, tested and commissioned many innovative timber treatment plants that utilise cutting edge engineering technologies.
Our experience allows us to supply you with the technology to utilise the latest generation of creosote and oil based preservatives for wood preservation.
When to use Creosote treatment?
If you are looking for the longest possible service life from timber impregnation, creosote is the product you need to use.
It has a very high tolerance to fungi, insects, and marine borers and it also naturally repels water.
Creosote is not allowed to be used residentially and can only be used commercially. This means its common uses are things like piling, telephone & utility poles, and railway sleepers.

Full Cell Process (Bethel)
- Timber charge is sealed in the treatment vessel
- Vacuum applied causing timber cells to be evacuated of air
- Vessel is flooded while the vacuum is maintained
- Preservative is forced into the timber under hydraulic pressure until refusal i.e. no more preservative can be taken up by the timber
- Vessel is emptied
- Low pressure inside treatment vessel draws in surface solution when vented to atmosphere
- Vacuum applied to the timber again to evacuate left over preservative
- Left over preservative is recovered to the storage tank
- Timber charge removed from treatment vessel









Rueping Process
- Timber charge is sealed in the treatment vessel
- Pneumatic pressure applied to timber
- Vessel is flooded while the pneumatic pressure is maintained
- Preservative is forced into the timber under hydraulic pressure
- Vessel is emptied
- Low pressure inside treatment vessel draws in surface solution when vented to atmosphere
- Vacuum applied to the timber again to evacuate left over preservative
- Left over preservative is recovered to the storage tank
- Timber charge removed from treatment vessel
All equipment can be supplied either Ex-Works or Fully Installed, whichever works best for you. We have access to a wide network of transport, crane and plant hire providers to allow us to achieve even the most complicated of installations.
We also have our own lifting equipment including the following: –
- Reachstacker capable of lifting 45T
- Wheeled Hydraulic Lifting Frame capable of lifting 80T
- 2no. 10T Fork Lift Trucks
Any of these can be transported to site if the job requires it.
