I'm looking for some advice as to building a garden retaining wall. It's ti me to work on the garden. My garden is very overgrown, but 2/3 down there i s a 2' drop with an old brick wall across the garden maintaining the differ ential.
The wall is unmortared and falling apart - it has completely collapsed in p arts. I want to create a new mortared retaining wall across the garden, but am worried about how to prevent the wall from being collapsed by the 24 in ches of soil pushing against it.
I've got enough bricks I think for a double thickness wall (ie full brick w idth), but am not sure about how much foundations I will need for this wall .
Any suggestions (or links to relevant material) greatly appreciated.
