Step-by-Step Guide

Follow these detailed steps to construct your railroad tie retaining wall:

Step 1: Planning and Site Preparation

Begin by planning the layout of your wall. Mark the area with stakes and string to outline the wall's boundary. Make sure to measure the height and length needed.

Step 2: Digging the Trench

Excavate a trench to a depth of about 1 foot. This will help ensure stability and drainage. The width should be about twice the width of the railroad ties.

Step 3: Adding a Gravel Base

Fill the bottom of the trench with 4-6 inches of gravel to promote drainage and prevent water buildup behind the wall.

Step 4: Installing the First Layer of Ties

Lay the first layer of railroad ties in the trench, ensuring they are level. Use a level to check each tie.

Step 5: Securing the Ties

Secure the ties using heavy-duty nails or screws. If desired, you can also pour concrete around the base for added stability.

Step 6: Building Additional Layers

Repeat the process, offsetting each layer for stability. Ensure that each layer is level before proceeding to the next.

Step 7: Adding Drainage

Install landscape fabric behind the wall to filter out soil, followed by more gravel to aid drainage.

Step 8: Finishing Touches

Backfill the area behind the wall with dirt, compacting it as you go. Ensure the top of the wall is even and smooth.
