Hi folks ,
Just wanted to get some input from you on how to protect this timber. We have this open in drive way forming a wall but I can see water is already making inroads and potentially have to replace this in long term.
Is there any type of sealant or product I can use to protect these from breaking down ?

Hi @binaryzer0,
The timber used in that retaining wall is H4 treated pine. H4 treatments are suitable for use in situations where the timber is in contact with the ground or is continually damp. You'll find water will make inroads and then it will dry out again. This shouldn't cause any damage and the timber will last for many years just fine.
Any sealer you put on the timber will still allow water to enter from the soil side which you can't get to. I would imagine sealing the visible parts of the wall would only accelerate the rotting of the timber internally as the moisture can't escape.
I don't believe there is anything you need to be concerned about, but please feel free to ask further questions.
