As someone who has been in the building industry for over a decade, I’ve always been passionate about using the best materials available. Timber, with its natural beauty and versatility, has always been a go-to for many outdoor projects. But as any seasoned carpenter knows, untreated wood can be a ticking time bomb. Exposure to the elements, pests, and decay can significantly reduce its lifespan, which is where Alkaline Copper Quaternary (ACQ) treatment comes into play.


ACQ treatment is a true game-changer in our industry, not only for its effectiveness but also for its eco-friendly credentials. Unlike older methods that relied on toxic chemicals, ACQ uses a combination of alkaline copper and quaternary ammonium compounds to strengthen the wood against decay. This approach not only extends the life of the timber but also aligns with environmentally conscious values—a win-win in my book.


ACQ treatments don't rely on toxic chemicals


The process of ACQ treatment is as straightforward as it is effective. Timber is placed in a chamber where the air is first removed (vacuum) and then injected with the ACQ solution under pressure. This method ensures that the treatment penetrates deeply into the wood, offering comprehensive protection against fungi, insects, and other decay-causing organisms. This deep impregnation is crucial for ensuring the durability and longevity of the timber, especially in the harsh outdoor conditions we often face here in Queensland.


What I particularly appreciate about ACQ treatment is its environmental profile. The shift towards using copper and quaternary compounds, which are far less harmful to the environment compared to older treatments, is a significant step forward. By choosing ACQ treated timber, not only are you getting a product that lasts longer, but you’re also contributing to sustainable forestry practices—a cause that’s close to my heart.
