Hi all,
I have a long and thin garden that is has a gradual upward slope from bottom to top. I am going to install a number of sleeper retaining walls to create some flat and useable space. The walls will be about 40cm high and about 8M wide. I have two questions:
1. On the left and right hand side of the garden are standard fence panels running all the way up. As I am raising the ground behind the retaining walls, what is the best way of protecting the fence panels either side from rotting from the soil that is sitting against them?
2. The walls will be about 40cm high and I plan to build them with sleepers laying on their side (thinnest part). Do I have to put concrete fence posts in first to secure the sleepers against or is the wall short enough for me to get away without them? If they are definitely needed how do I secure the bottom sleeper (in the trench) to the post? Practically I will not be able to get inside the trench to drill?
Really appreciate any advice you can give me
