  1. My dad built a deck 30 years ago from treated lumber. I believed they used arsenic back then to treat the lumber. The steps on the deck became buried from water rushing over. Last year I removed the steps to install a ramp. The bottom step was in good shape haha! I was surprised! I guess they don't treat wood like they used too!!

  2. as a 15 million $ man and a contractor I can tell you that there are different grades of treated lumber. Most of the ground contact lumber last 40 years…about as long as concrete. the lumber treated for docks is even better.

  3. I think the key to your solution is the gravel and the drainage. If you put enough gravel behind these walls and the correct drainage pipes, your problem could be solved. Remember, anything you can do to improve the drainage and reduce the water accumulation in these areas, the longer these walls will last.

  4. Thanks for the insight and the advice. I would imagine wood retaining walls would last longer with the proper drainage system behind them and if they were located in a shady area, regularly attacked by sprinklers or other forms of moisture.

  5. @ey468 Thanks for the useful tip. Something like that would definitely extend the life of a wood retaining wall. If you want to extend the life of practically any retaining, you need to keep as much water as possible away from it.

  6. @weekofhorror To answer your question simply, wood rots and I've seen practically every type of treated wood rot when it's exposed to too much moisture. This wall is located in the shade, for most of the day and less than 200 yards from the ocean. This type of construction doesn't make much sense to me.
