As homeowners or builders, we constantly look for materials that will give our homes or clients' homes a lasting finish. One key element that often goes underestimated is the importance of pressure-treated wood. From fence panels to railway sleepers, pressure-treated wood can make a significant difference in the durability and appearance of timber. In this article, we will explore the process of pressure treating wood and how it can benefit your building projects.

What is Pressure Treating?

Pressure treatment is a process that involves injecting preservative chemicals into wood under high pressure to protect it from pests, rot, and decay. This technique helps to extend the life of timber and ensures that it retains its strength and aesthetic appeal for years to come. Pressure-treated wood is particularly popular for fence panels and railway sleepers, where it must withstand being constantly exposed to the elements.

How Does Pressure Treatment Work?


Before the wood can be treated, it needs to be carefully prepared. This means ensuring that the timber is free from dirt, debris, and moisture. The wood is then placed into a treatment cylinder, which will hold it securely throughout the process.

Treating the Wood

Once the wood is ready for treatment, it is placed inside a pressurised cylinder. A vacuum is then applied to remove any air from the wood's surface and pores. Next, a preservative solution is pumped into the cylinder, which is then pressurised, forcing the solution deep into the wood's grain.

Finally, the wood is removed from the cylinder and left to dry and cure. This allows excess preservative to drain away and the wood to reach its desired moisture content. The entire process can take several days, depending on the type and size of the timber being treated.

Benefits of Pressure-Treated Wood


Pressure treatment significantly increases the life span of wood, particularly in outdoor applications like fence panels and railway sleepers. The wood becomes more resistant to rot, decay, and insect infestations, meaning it can remain strong and functional for years to come.

Low Maintenance

Using pressure-treated wood reduces the need for regular maintenance. Unlike untreated wood that requires frequent sealing and staining to maintain its appearance, pressure-treated wood retains its finish and requires only occasional cleaning.


Though pressure-treated wood may be more expensive upfront compared to untreated wood, it often proves to be a more cost-effective solution in the long run due to its durability and low maintenance requirements.

Providing the Best Timber Solution

Opting for pressure-treated timber ensures that your fence panels and railway sleepers remain sturdy and weather-resistant, proving to be a valuable investment for homes and businesses alike.
