Idaho Wood Preserving

Pressure-treated lumber is wood that is placed in a pressure chamber and immersed in a liquid preservative. The chamber pushes the preservative chemical deep into the wood fibers. Using a pressure chamber ensures that the chemical permeates throughout the wood, instead of merely soaking it, which risks having untreated sections of wood. Pressure treating wood is ideal for outdoor uses as it preserves and protects the wood against pests and wood rot. This can help to preserve your wood for up to decades longer than untreated wood.

We proudly offer pressure-treating services with NatureWood (ACQ by Osmose). ACQ or NatureWood, is manufactured by Koppers Performance Chemicals and is an arsenic-free preservative with very similar characteristics and performance to that of CCA. We have state-of-the-art automated technology which ensures the wood is properly treated. Our process meets all AWPA (American Wood Preservative Association) standards and guidelines.

Our treat plant utilizes an 80’x 6’ pressure treating retort, three 16,000-gallon work tanks, two 10,000 concentrate tanks, and an 18,000 bulk water tank, all housed in an 18,000 square foot heated building. We own and operate the only pressure treating plant in nearly 400 miles!
