The EHT staff has relied on Wolmanized® Wood for outdoor projects for over 20 years. Southern Pine pressure-treated with Wolmanized® copper azole preservative treatment. This No. 1 grade wood is treated with micronized CA-C for Ground Contact as well as for Freshwater Immersion, meeting all building code requirements. It’s a great building material for docks, decks, retaining walls, fences, picnic tables, planter boxes, walkways, sill plate and structural members. The lumber’s S4S designation means it’s sanded on four sides for a finished, professional look. Also, It’s important to note that Wolmanized® Outdoor wood has earned the Good Housekeeping Seal, has been certified by Home Innovation Research Labs as meeting requirements for termite-resistant materials in the National Green Building Standard™, and has been verified by the internationally recognized EcoSpecifier. It comes with a limited warranty for most residential applications and, to top it off, it costs less than alternatives such as tropical hardwoods and artificial wood.
