It is the process of treating wood with chemicals or any other biochemical substances that can help to prevent or slow down the deterioration of wood caused by either environmental factors or by organisms such as fungi, insects, and wood borers.
Pressure treatment is a wood preservation process used to enhance the durability and longevity of wood. It involves impregnating wood with preservatives under high pressure, which helps protect it from decay, insects, and other environmental factors.
Preserving wood is essential because it extends the life of timber products thus reducing the need for frequent replacements, saving both time and money. It reduces the demand for cutting down more trees resulting in sustainable forest practices. Treated wood is equally less susceptible to structural damage, making it safer for construction and use in various applications.
The lifespan of preserved wood depends on various factors, including the type of preservative used, the preservative application process, service conditions and the environmental conditions. However, properly preserved wood can last for a long time.
Waterborne preservative-treated wood is suitable for various applications, including power transmission poles, fencing posts, construction posts, decks, play structures, and landscaping.
Most wood preservatives are restricted to be handled by professionals only due to their hazardous nature.
