What is the difference between wood that is treated for ground contact and wood that is treated for above ground use?
Lumber that is acceptable for above ground use can function in a variety of ways but should not come in contact with the ground. When wood is required to come into contact with the ground, it’s important to use specially treated lumber that is designed and prepared for this purpose. Ground contact pressure treated lumber is developed to handle the additional moisture it encounters when meeting the ground. Click here for more information on the available levels of treatment.
