We can't get grass to grow in spots in our backyard due to a combination of dogs, trees, and shade.
Behind the house is a hill. A third of it has a retaining wall built with rail road ties. It has been there since before I moved into the house as a 5 year old which was 25 years ago. The other 2/3rds of that hill right behind the house have been eroding massively over the last 3 years to the point that you can see the foundation of the house, walls in the house are cracking and a ball on the floor will roll toward the hill every time (i.e., the house is falling downhill).
Now here is the big key: We are planning on moving, and we are on a shoestring budget.
Is my best bet to build a retaining wall that matches the other one? Should I do concrete blocks instead? Stone?
What is the cheapest way to do this that won't look horrible?
