When you’re building decks, fences, or outdoor structures, one of the first decisions you’ll face is what kind of lumber to use. Pressure-treated wood is designed to withstand the elements — moisture, insects, and decay — by being infused with preservatives under high pressure. During treatment, lumbers are placed in a sealed cylinder where a vacuum removes the air and replaces it with a preservative solution. This process allows the treatment to deeply penetrate the wood fibers, helping the material resist rot and damage forbears, even in Alberta’s freeze-thaw climate.

Modern pressure-treated lumber uses copper-based preservatives that are safer and more environmentally friendly than older formulations. This makes its durable, affordable, and versatile choice for everything from framing and fence posts to deck boards and landscaping projects.
