Hi, looking to make some of the space under a d raised eck useful. The land under the deck is on a slope, so I have to level it and put some kind of retaining wall, then gravel in the newly leveled area. Deciding whether to use wall block or wood. If build retaining walls with block but not wood. Considering wood off being less expensive and bc looks aren't too important, but current pressure treated seems to hold up poorly. I'm open to other ideas you may have. thanks.
What are your opinions on this?
