How to repair railroad tie retaining wall?

1. Start by digging a trench around the base of the wall. You will need to dig down a few feet and then wider than the circumference of your railroad tie wall.

2. Remove any loose, decaying ties and replace with new ones. Make sure that you use treated wood for maximum longevity.

3. Fill the trench in with gravel and tamp down to create a solid foundation.

4. Place the railroad ties back into their original positions, making sure that they are firmly against each other.

5. Replace any missing mortar between the ties as necessary.

6. Re-stack stones or bricks that have been dislodged from the top of the wall to give it a more finished look.

7. Once everything is secure and in position, add a top layer of mortar between the stones and the ties. This will help hold them together.

8. Add soil or other ground cover material to the top of the wall to prevent erosion and keep the soil secure.

9. Finally, monitor the wall regularly for signs of damage or shifting.
