How to build a timber retaining wall
To build a retaining wall in wood, begin by excavating the area where you want the wall to be erected. If the area is on a slope, you’ll have to grade the soil by inserting wood poles in the slope and stretching a masonry twine across them.
Next, you’ll have to construct a base trench by digging a ditch on the side of the wall that’s on a higher altitude. Fill it with multi-coloured stones and level it with a rake. Over the stones, place the first level of cement. Remember to wear gloves when you do this.
Now, place the initial row of wood flat into the ditch, and follow it up with a second row of wood. For a strong wall, stagger the rear parts of the wood. Use spikes to attach the timber layers of one row to the ones below it. Work with a sledgehammer and a brick chisel to build a strong wall.
When the wall rises, push the earth in behind it tightly. As you fill the back portion with sand and soil, strengthen the wall with cement as it goes higher. There should be increasing numbers of cement mixes between the retaining wall and the ditch so that the wall gets sufficient material strength.
The higher the wall rises the farther the slope will be from the top of the wall. Top up any gap in the trench with crushed stones and earth, ensuring that the final level is barely a few inches below the top of the wall. You can now paint it or stain it the way you want to.
Your retaining wall is now ready.
