So, we’ve got this spot by the entrance to the new wood shop that needs a retaining wall. We had to dig the floor to the new wood shop down about 10 inches. On top of the fact that it was already 8 inches lower than the shop next to it. This left us with about 18 inches of hill that just can’t wait to slide in front of the door and block the way like a big dirt bouncer at a wood shop club. So we decided to build a railroad tie retaining wall to hold all the dirt back and guess what? We had a bunch of railroad ties laying around the farm. Perfect!
