FAQs

How many railroad ties do I need for a retaining wall? The number of railroad ties you need depends on the length and height of the retaining wall. As a rough estimate, for a 4-foot high wall, you might need about 1 railroad tie per linear foot of wall. So, if your wall is 20 feet long, you’d need approximately 20 ties. Keep in mind that this is a very rough estimate, and the actual number may vary based on factors like tie dimensions and wall design.

How do I calculate how much retaining wall I need? To calculate the amount of retaining wall material you need, measure the length, height, and thickness of the wall you plan to build in feet. Then, multiply these dimensions together to find the cubic feet of material required. For example, a 5-foot high, 1-foot thick, and 20-foot long wall would require 100 cubic feet of material.

Can you build a retaining wall with railroad ties? Yes, you can build a retaining wall with railroad ties. They are a popular choice due to their durability and strength. However, keep in mind that some areas have regulations regarding the use of railroad ties due to their treated wood and potential environmental concerns.
