Wood retaining wall ideas – choosing the right place and type of wall
The retaining wall in landscape design is an absolutely indispensable element that can not only decorate the site, but also divide it into zones. It can be a barrier and at the same time a rather original decoration of the exterior. You can build a wall from almost any material – concrete, gabions, bricks, natural stones – which are suitable for the natural conditions of soil and atmospheric phenomena of the local area, but many homeowners choose wood for its beauty and practicality.
Prior construction you need to understand the major elements of retaining walls in landscape design. Each wall consists of the following elements:
- The foundation is the most important part of the wall. The stability of the entire structure largely depends on foundation. Usually it is hidden under the ground, so it remains hidden from the eye.
- The body or the main part – brickwork, log, concrete or wood construction – this is the visible part of the retaining wall.
- Drainage – this element helps to protect the wall from the damaging effects of weather.
How to choose a place for a retaining wall? There are no limits – you can construct your wall anywhere you like. Any place is suitable except for those where moisture levels are really high. Wood is very quickly destroyed in a humid environment. For wetlands, areas with heavy snowfalls, rainfalls, spring floods of rivers and streams, under ground waters – it is better to choose an alternative and more durable material like stone or concrete. In addition, a wall made of wood is not the best choice for steep slopes where the wall will bear a great load.
How to choose the type of your wood retaining wall? There are three types of walls to choose from:
Vertical – all elements are perpendicular to the ground. They should go into the soil at a depth of minimum 30 cm, and strengthened by horizontal ties;
Horizontal – logs or beams are stacked upon each other, fastened together and the bottom row is anchored to the ground by long pieces of reinforcement which should be 0.5-1 m deep into the soil;
Combined – logs are laid horizontally between vertical posts.
The choice of the method of installation depends on several factors, the main ones being the length of the logs and whether the future wall will be curved or straight. If the logs or boards are long, horizontal laying is preferable. For complex shapes – semicircular or zigzag, for example, the vertical installation is a better choice. The boards need to be tightly fitted to each other to ensure that the decorative wall is monolithic.
Whichever type of construction you choose, you have to realize that the drainage system is essential for the lifetime and appearance of your wall. A bad drainage will increase the moisture factor is crucial for wood.
Wood retaining wall ideas – pros and cons of the material

Wood, like any material, has its advantages and disadvantages which homeowners need to know when choosing the materials for their landscape.

- Lifetime – when properly treated, installed and maintained, your retaining wall can last for more than 20 years.
The main disadvantages of wood retaining walls are:
- Wood is a material that easily absorbs moisture. To prevent future deformation, it is necessary to make them water resistant. To do this, you can cover each log or board with a composition of hot bitumen. Another option is burning the logs. However, you will need to be extra careful not to ruin the appearance of the boards.
- Wood is susceptible to rotting, especially in hot and humid areas. Yes, nowadays, the market offers pressure treated wood, which is more durable, but sooner or later you will need to renew or replace the wall.
- As we mentioned before, wood is not a good choice for retaining walls with more complex shapes, as it is not as strong and durable as alternative materials like metal or stone.
- Low quality wood will degrade quickly.
- Wood is susceptible to insect attacks. Termites, for example
