Certain boards need more treatment than others depending on the application of the lumber. Heavier treated lumber tends to be less stable, causing more warping, twisting, checking and cracking of the board. If the boards are going to be supporting a structure, have leaves, mulch or vegetation build-up on it regularly or wet on a regular basis, it is recommended to go with the below-ground lumber. All of our lumber that is stocked above-ground can be special ordered as ground-contact kiln-dried.
