A timber retaining wall would last for more than twenty years if it is built with proper and high-quality raw materials. As mentioned above, good quality materials should be used! Especially the wood should be of premium quality because this wood stays attached to the soil throughout. And as there is moisture content present in the soil, the wood may start to rot a few days later after the installation process.

This shortens the lifespan of the wood retaining walls and in no way lets these walls survive more than thirty years or so. This thing does not happen with the concrete walls.

Behind the timber retaining walls, mostly plants are planted by the owners, and as you all know, watering the plants is mandatory.

The water content put into the plants every day is to be taken care of very minutely. Water should not gather in a particular place behind the timber retaining wall. This isn’t good for the wall.

Both the moisture and the water content speeds up together and decomposes the wall. Hence, a drainage system is essential if you are planning to have a timber retaining wall. This would bring some positivity and help the wooden wall stay safe for the long forty years.

Timber is very expensive, and if you are not willing to spend more on retaining walls, then you may go for other reasonable alternatives which are available in the local marketplace.

You can add a waterproof sheet in the backside of your timber retaining wall to separate the direct contact of the soil and the wall. Gravel packing is also possible behind the wall.

This is done at the bottom of the wall, where usually the water gets accumulated during the rainy season. The gravel increases the length of the wall, and therefore water does not accumulate there.

This ensures both a bit of safety and positivity. But during installation, if there are any weep holes found in the bottom, this will risk the life of the wall.

So, better take precautions before it is too late and let your wooden retaining wall live more than thirty years.
