Treatment Type

Mother Nature doesn’t care if your wood is properly treated. But we do.

Everything about extreme natural environments–water, salt, organisms, wind, heat, cold, violent storms, floods–is a potential disaster to any wood-based structure or building. To counter these destructive forces, our own chemical scientists have developed proprietary, industry-leading treatments that are innovative, effective, and proven to stand the test of time.
