How to Make a Retaining Wall Out of Wood?

Here are the steps I came across to build a wood retaining wall.

1. Remove the grass and loose soil from the area where you want the wall.

2. Then, dug a trench about a foot deep to create a solid base. The trench needs to be level.

3. Cut the wooden timbers to size and treat them to prevent rot.

4. To keep the first row of timbers in place, hammer in rebar stakes at even intervals along the trench. 

5. Drill the holes in the timbers to fit large spikes and stack the wood layers carefully.

6. To prevent water buildup, lay a perforated drainpipe behind the first row of timbers.

7. For extra support, add horizontal wood beams (deadmen) and tiebacks, secure them deep into the soil behind the wall. 

8. Finally, fill the space behind it with gravel for drainage and topped it off with soil. 

I tried this on my own, but it was out of my knowledge, so finally I hired a professional renovation service. I hope you understand how to build a wood retaining wall.

How to build a wood retaining wall?

Before starting any construction, it is better to check with your local authorities or building department to determine if you need any sort of permit. Also, check whether there are any specific regulations regarding the construction of retaining walls in your area.

Evaluate the area where you want to build the retaining wall. Do not forget to consider factors such as the height of the wall, soil conditions, drainage, and the weight of the wall. Make sure there is adequate space for the wall and proper clearance from any structures or property lines.

Buy the necessary materials for your wood retaining wall, like pressure-treated lumber, gravel, drainage fabric, screws, suitable foundation material, and more. You will also need tools such as a shovel, level, tape measure, circular saw, drill, and more.

Use string or some other material to mark the layout and boundaries of the retaining wall. Note the height and length of the wall, and check for proper drainage by sloping it slightly backward.

Dig a trench where the retaining wall will be located. The depth of the trench should be based on the desired height of the wall, taking into account the foundation material and the thickness of the wall's base.

Add a layer of gravel to the bottom of the trench for drainage. Compact the gravel and ensure it is level. Additionally, lay down a layer of landscape fabric to prevent soil from seeping through the wall.

Next, you must begin with the bottom row of your retaining wall. Place the first row of pressure-treated lumber into the trench, using a level to ensure it is level both horizontally and vertically. Secure the boards together using appropriate screws or connectors.

Depending on the height of the wall and local regulations, you may need to instal drainage pipes or weep holes to allow water to escape. I will suggest you consult with a professional to determine the specific requirements for your area. These are the DIY wood retaining wall strategies. 

Once the retaining wall is complete, backfill the remaining soil behind it and compact it in layers. It will be good to apply a wood preservative or sealer to protect the wood from moisture and extend its lifespan. Make sure you inspect and maintain the wall regularly to ensure its stability and address any issues promptly.
