Allweather Wood’s structural timbers and dimension lumber receive NatureWood® or Wolmanized® uCAC preservative to meet fresh water building code requirements. When used for docks and floats, our products ensure a long and safe life.

Allweather Wood also offers structural timbers with a higher degree of preservative protection for structures immersed in saltwater or exposed to saltwater splash. These timbers are treated to a .60pcf retention in either NatureWood® (ACQ) or CCA preservatives and can be special ordered from any Allweather Wood manufacturing facility.
