In partnership with a European manufacturer, we offer a range of pressure creosoted timber. The longer lifespan is the major appeal and in equestrian environments this is extended further by the reduced chewing damage normally eroding fencing every day.
In peeled or machined smooth finish, the range is extensive, please call 01992 578496 or fill out an enquiry form for details of our full range.
In areas where lots of contact is possible with the fence, but creosoted lifespan is desired, we also offer the part treated option. This is ideal for public areas. The posts are treated with the standard green treatment, then again on the bottom third of the post with creosote. This results in a post with creosote on the bottom third and standard green on the rest. This lower third is the area in contact with the ground and the most otherwise most likely to rot. So by treating in this way, the extended lifespan is achieved without the normal hazards to people and animals that usually accompanies pressure.
Please see our manufacturers impregnation processes below.
Pressure impregnation for comprehensive impregnation
Creosote impregnation is recommended when there is little chance of skin contact and the wood must last a long time.
Our manufacturers impregnation cycle for class 2 wood:
1. Pre-pressure phase: The impregnation agent is heated in the boiler. The pre-pressure phase allows the wood to acclimatise to the creosote.
2. Pressure process: The agent is pressed into the wood.
3. Vacuum: The agent is pumped into the holding tank, allowing the wood to drain.
We only use type C creosote because this creosote is more ecologically friendly and gives off fewer odours than other types of creosote.
Pressure units and times vary depending on the type of wood. Since only sapwood can be impregnated, some types of wood lend themselves better to impregnation than others.
Bath impregnation - for untreated or salt-impregnated wood
Part impregnation gives the lower part of a wooden post, i.e. the most exposed part, additional protection.
This process is recommended where there is contact with the woodbut where the postsmust last a long time.
Our manufacturers impregnation process:
1. The wood is placed vertically in the carrier trolley and lowered into the creosote.
2. The creosote is then heated. When the required temperature is reached, the creosote is kept at this heat for three hours.
3. The impregnation agent is allowed to cool to 50°C and the wood is removed from the agent.
4. The posts drain over a vat.
Due to external temperatures, the process takes longer in summer than in winter.
Maximum 1m creosote
