A question for the landscapers out there. A fairly large garden that I maintain was landscaped five years ago and includes some self binding gravel paths and a lot of steps. I believe it is oak that was used as the retainers/risers and would have expected these to have lasted quite a number of years. However they are already falling apart (not helped by the inadequate screws) and a lot of them are rotting off. Should Oak not last a lot longer than that ?
So now some repair work is necessary I am wondering what you would use and if there is anything else that can be done to help preserve them, the owners really don't want to have to replace them every five years, there's probably about 120 of them. I will try and add a photo of the problem. I'm not going to be doing the job myself but want to know that it is carried out properly, a few steps have been replaced recently with tanalised pine and I'm pretty sure this is not the answer.
